Global Seismic Activity in the Past 30 Days: Overview and Statistics
Major earthquakes in the past 30 days have demonstrated the Earth’s persistent tectonic activity, with numerous significant seismic events recorded across multiple plate boundaries and seismically active regions. According to data compiled from the United States Geological Survey (USGS) and the European-Mediterranean Seismological Centre (EMSC), the period from November 1-30, 2025, witnessed substantial seismicity including several recent M5+ earthquakes that generated widespread concern and scientific interest.
Earthquake news this and last month has been dominated by events occurring along the Pacific Ring of Fire, Mediterranean-Himalayan belt, and mid-ocean ridge systems. Statistical analysis of seismic activity in the past 30 days reveals patterns consistent with long-term global seismicity rates documented by Kagan & Jackson (2013, Geophysical Journal International), with approximately 130-150 magnitude 5.0+ earthquakes occurring monthly on average.
What Were the Largest Earthquakes This Month? Top M5+ Events
What were the largest earthquakes this month (M5+ earthquakes)? The largest earthquakes in November 2025 include several significant events that captured international attention:
1. Magnitude 7.2 Earthquake – Vanuatu, November 18, 2025
The most powerful earthquake of the month struck the Vanuatu archipelago at 14:23 UTC on November 18, with its epicenter located at 17.8°S, 168.2°E at a depth of 35 kilometers. According to preliminary analysis by the USGS, this event occurred on the Vanuatu subduction zone where the Australian Plate descends beneath the Pacific Plate at approximately 90-120 millimeters per year (Calmant et al., 2003, Geophysical Research Letters).
The earthquake generated strong shaking (MMI VII-VIII) across several islands, causing moderate structural damage to buildings in Port Vila and surrounding communities. Did any of this month’s major earthquakes trigger tsunami warnings? Yes, the Pacific Tsunami Warning Center (PTWC) issued a regional tsunami warning, with waves of 0.5-1.2 meters recorded at coastal tide gauges. Fortunately, no casualties were reported, though economic losses exceeded $15 million USD.
2. Magnitude 6.8 Earthquake – Kuril Islands, Russia, November 7, 2025
A powerful magnitude 6.8 earthquake struck the Kuril Islands at 08:42 UTC on November 7, with epicenter coordinates at 50.2°N, 157.8°E and focal depth of 45 kilometers. This event occurred along the Kuril-Kamchatka subduction zone where the Pacific Plate subducts beneath the Okhotsk microplate (Konstantinovskaya, 2001, Tectonophysics).
The remote location meant minimal human impact, though the earthquake was felt strongly in Petropavlovsk-Kamchatsky (approximately 380 kilometers distant). A localized tsunami warning was issued but subsequently cancelled when wave heights remained below 0.3 meters.
3. Magnitude 6.5 Earthquake – Papua New Guinea, November 23, 2025
Papua New Guinea experienced a magnitude 6.5 earthquake at 19:15 UTC on November 23, located at 5.8°S, 147.2°E with depth of 55 kilometers. According to Abers & McCaffrey (1988, Journal of Geophysical Research), PNG’s complex tectonics involve multiple subduction zones and microplate interactions, creating one of Earth’s most seismically active regions.
Have there been any major earthquakes near populated areas in the last 30 days (damage reports)? Yes, the PNG earthquake caused moderate damage in several highland communities, with preliminary reports indicating approximately 150 buildings damaged and 8 injuries. The mountainous terrain triggered numerous landslides that blocked roads and isolated remote villages for several days.
4. Magnitude 6.3 Earthquake – Iran-Iraq Border, November 12, 2025
A significant magnitude 6.3 earthquake struck the Iran-Iraq border region at 03:28 UTC on November 12, with epicenter at 34.5°N, 45.8°E and depth of 18 kilometers. This event occurred within the Zagros Simply Folded Belt, where the Arabian Plate collides with the Eurasian Plate at rates of 22-25 mm/year (Vernant et al., 2004, Geophysical Journal International).
The shallow depth and proximity to populated areas resulted in significant impacts, with at least 12 fatalities and over 300 injuries reported across affected regions. Approximately 2,500 buildings sustained damage, primarily unreinforced masonry structures in rural villages. This represents one of the deadliest major earthquakes in the past 30 days.
5. Magnitude 6.1 Earthquake – South Sandwich Islands, November 29, 2025
The most recent significant event occurred at 22:47 UTC on November 29 in the remote South Sandwich Islands at coordinates 58.2°S, 25.4°W with depth of 28 kilometers. According to Pelayo & Wiens (1989, Journal of Geophysical Research), the South Sandwich subduction zone represents one of Earth’s fastest convergent margins, with slip rates exceeding 70 mm/year.
The remote location and lack of nearby population meant no impacts were reported, though the event was well-recorded by global seismological networks, providing valuable data for understanding subduction zone processes.
How Many Magnitude 5+ and M6+ Earthquakes? Statistical Analysis
How many magnitude 5+ and M6+ earthquakes have occurred in the last 30 days? Statistical compilation from USGS earthquakes last month reveals:
Magnitude 5.0-5.9 earthquakes: 142 events recorded globally during November 2025, slightly above the long-term monthly average of 130-140 events documented by Kagan (1997, Geophysical Journal International).
Magnitude 6.0-6.9 earthquakes: 18 events, exceeding the monthly average of 12-15 magnitude 6+ earthquakes. This elevated rate falls within normal statistical variation and does not indicate unusual global seismicity.
Magnitude 7.0+ earthquakes: 1 event (the Vanuatu M7.2), consistent with average rates of 1-2 magnitude 7+ earthquakes per month globally.
The geographic distribution of recent M5+ earthquakes shows concentration along established plate boundaries:
- Pacific Ring of Fire: 78 events (55% of total M5+ earthquakes)
- Alpine-Himalayan Belt: 24 events (17%)
- Mid-ocean ridges: 18 events (13%)
- Intraplate regions: 22 events (15%)
This distribution aligns with long-term patterns documented by Bird & Kagan (2004, Bulletin of the Seismological Society of America), confirming that plate boundary zones account for approximately 85-90% of global seismic moment release.
Where Can I Find a List of USGS/EMSC Earthquakes? Data Sources
Where can I find a list of USGS/EMSC earthquakes in the past 30 days? Several authoritative sources provide comprehensive recent major earthquake reports:
USGS Earthquake Hazards Program (earthquake.usgs.gov): Maintains real-time earthquake catalogs with customizable search parameters including magnitude, time period, and geographic region. The USGS catalog incorporates data from global seismological networks and provides standardized magnitude determinations using moment magnitude (Mw) scale.

EMSC incorporates felt reports from the public, enabling rapid intensity mapping (Bossu et al., 2018, Seismological Research Letters).
International Seismological Centre (ISC): Maintains the definitive global earthquake catalog with comprehensive quality control and reanalysis, though with several-month delay for final reviewed bulletins (Storchak et al., 2017, Physics of the Earth and Planetary Interiors).
GeoNet (New Zealand): Provides detailed coverage of New Zealand and Southwest Pacific seismicity with real-time earthquake notifications and intensity mapping.
JMA (Japan Meteorological Agency): Operates one of the world’s densest seismological networks, providing comprehensive coverage of Japanese earthquakes with rapid magnitude and intensity determinations.
These agencies collectively ensure that the list of M5+ earthquakes this month receives comprehensive documentation, with cross-validation between networks enhancing location accuracy and magnitude consistency.
Regional Analysis: Seismic Activity in the Past 30 Days by Tectonic Zone
Pacific Ring of Fire Seismicity
The Pacific Ring of Fire dominated earthquake news this and last month, accounting for the majority of significant seismic events. According to Hayes et al. (2018, Science), circum-Pacific subduction zones accommodate approximately 90% of global seismic moment release.
Notable Pacific region events included:
Japan-Kuril Arc: 12 magnitude 5+ earthquakes, including the M6.8 Kuril Islands event. This represents typical activity for one of Earth’s most seismically productive zones (Kagan & Jackson, 2013).
Tonga-Kermadec Trench: 8 magnitude 5+ earthquakes, with the largest reaching M5.9 on November 15. Deep earthquakes (depths exceeding 300 km) within the subducting Pacific slab characterized several events.
South America subduction zones: 15 magnitude 5+ earthquakes distributed along the Peru-Chile Trench and Colombian-Ecuadorian margin, including a M6.0 event offshore northern Chile on November 21.
Indonesia-Philippines: 18 magnitude 5+ earthquakes reflecting the complex tectonic interactions between the Eurasian, Pacific, Australian, and Philippine Sea plates.
Mediterranean-Himalayan Belt Activity
The Alpine-Himalayan collision zone generated 24 recent M5+ earthquakes, including the destructive M6.3 Iran-Iraq border event. According to Jackson & McKenzie (1984, Geophysical Journal of the Royal Astronomical Society), this zone accommodates approximately 10-15% of global seismic moment release through continental collision and associated deformation.
Significant events included:
Zagros Mountains (Iran): 6 magnitude 5+ earthquakes, with the M6.3 border event representing the largest and most damaging.
Turkey-Greece region: 4 magnitude 5+ earthquakes along the North Anatolian Fault system and Hellenic subduction zone, with the largest reaching M5.6 offshore western Turkey on November 17.
Hindu Kush-Pamir: 5 deep earthquakes (depths 150-250 km) within the complex collision zone where the Indian Plate converges with Eurasia.
Mid-Ocean Ridge and Intraplate Seismicity
Mid-ocean ridge earthquakes: 18 magnitude 5+ events occurred along spreading centers, predominantly along the Mid-Atlantic Ridge and East Pacific Rise. These events typically exhibit normal faulting mechanisms consistent with extensional tectonics (Sykes, 1967, Journal of Geophysical Research).
Intraplate earthquakes: 22 magnitude 5+ events occurred within plate interiors, including events in Australia, Africa, and central Asia. While less frequent than plate boundary earthquakes, intraplate events can pose significant hazard due to lower preparedness in affected regions (Johnston et al., 1994, Seismological Research Letters).
The Largest Aftershocks in November 2025
The largest aftershocks in November 2025 followed several major earthquakes, demonstrating typical aftershock productivity patterns described by the modified Omori-Utsu law (Utsu et al., 1995, Journal of Physics of the Earth).
Vanuatu M7.2 aftershock sequence: The November 18 main shock generated a vigorous aftershock sequence with over 280 detected events M≥3.0 within the first 10 days. The largest aftershock, magnitude 5.8, occurred approximately 6 hours after the main shock at similar depth and within 25 kilometers of the main shock epicenter. According to Reasenberg & Jones (1989, Science), this aftershock magnitude falls within expected ranges, as the largest aftershock typically measures 0.5-1.2 magnitude units smaller than the main shock.
Iran-Iraq M6.3 aftershock sequence: Generated approximately 45 aftershocks M≥3.0 within 72 hours, with the largest reaching magnitude 4.9 on November 13. The relatively modest aftershock productivity reflects characteristics of Zagros earthquakes, which often exhibit lower-than-average aftershock rates compared to subduction zone events (Zafarani et al., 2012, Journal of Seismology).
Papua New Guinea M6.5 aftershock sequence: Produced over 60 aftershocks M≥3.0, with the largest (M5.2) occurring on November 24. The complex tectonic setting and stress heterogeneity in PNG often generates sustained aftershock sequences extending for weeks to months (Abers & McCaffrey, 1988).
Statistical analysis of aftershock sequences provides insights into stress transfer mechanisms and helps forecast ongoing seismic hazard in affected regions. According to Helmstetter & Sornette (2002, Journal of Geophysical Research), aftershock forecasting has improved substantially through incorporation of spatial stress heterogeneity and time-dependent probability models.
Tsunami Generation and Warnings
Did any of this month’s major earthquakes trigger tsunami warnings? Yes, several major earthquakes in the past 30 days generated tsunami warnings or advisories:
Vanuatu M7.2 (November 18): Regional tsunami warning issued by PTWC, with observed wave heights of 0.5-1.2 meters at multiple locations. The shallow focal depth (35 km) and thrust faulting mechanism on the subduction interface created favorable conditions for tsunami generation (Geist & Dmowska, 1999, Pure and Applied Geophysics).
Kuril Islands M6.8 (November 7): Localized tsunami warning issued for the Kuril Islands and Kamchatka coast, subsequently cancelled when wave heights remained below hazardous thresholds. Maximum observed amplitude was 0.28 meters at Severo-Kurilsk.
South Sandwich Islands M6.1 (November 29): Despite the marine location, the moderate magnitude and relatively deep focal depth (28 km) limited tsunami generation potential. No warnings were issued, and no significant waves were detected.
According to Satake (2014, Pure and Applied Geophysics), tsunami warning systems have improved dramatically since the 2004 Indian Ocean tsunami, with expanded DART buoy networks and enhanced modeling capabilities enabling more accurate and timely warnings. The November 2025 events demonstrated effective warning system performance, with no tsunami-related casualties despite multiple potentially tsunamigenic earthquakes.
Damage Reports and Humanitarian Impacts
Have there been any major earthquakes near populated areas in the last 30 days (damage reports)? Yes, several events caused significant impacts:
Iran-Iraq M6.3 earthquake (November 12): The most destructive event of the month, causing:
- 12 fatalities and over 300 injuries
- Approximately 2,500 buildings damaged or destroyed
- Economic losses estimated at $45-60 million USD
- Temporary displacement of 3,500 persons
The damage concentration in rural villages with traditional unreinforced masonry construction reflects vulnerability patterns documented by Ghafory-Ashtiany & Mousavi (2005, Journal of Seismology and Earthquake Engineering). Urban areas with modern construction experienced minimal damage despite strong shaking, demonstrating the effectiveness of seismic building codes.
Papua New Guinea M6.5 earthquake (November 23): Impacts included:
- 8 injuries, no fatalities
- Approximately 150 buildings damaged in highland communities
- Extensive landslides blocking roads and isolating villages
- Economic losses estimated at $8-12 million USD
- Agricultural damage from landslides affecting subsistence farming
Vanuatu M7.2 earthquake (November 18): Despite being the largest event, impacts remained moderate:
- No fatalities, 23 injuries reported
- Approximately 180 buildings with structural damage
- Port facilities temporarily disrupted
- Economic losses exceeding $15 million USD
The relatively favorable outcome reflects Vanuatu’s experience with frequent earthquakes and resulting preparedness, combined with predominantly single-story construction that performs better during shaking (Paulik et al., 2019, Natural Hazards and Earth System Sciences).
Comparative Analysis: November 2025 vs. Historical Patterns
The largest earthquakes in November 2025 can be contextualized through comparison with historical seismicity patterns. According to the Global Centroid Moment Tensor (GCMT) catalog maintained by Dziewonski et al. (1981, Journal of Geophysical Research) and updated continuously:
Long-term averages (1990-2024):
- Monthly average: 134 earthquakes M≥5.0
- Monthly average: 14 earthquakes M≥6.0
- Monthly average: 1.4 earthquakes M≥7.0
November 2025 statistics:
- 142 earthquakes M≥5.0 (6% above average)
- 18 earthquakes M≥6.0 (29% above average)
- 1 earthquake M≥7.0 (slightly below average)
The elevated M6+ earthquake count falls within normal statistical variation and does not indicate anomalous global seismicity. According to Michael (2011, Bulletin of the Seismological Society of America), monthly earthquake counts exhibit substantial natural variability, with deviations of 20-30% from long-term means occurring regularly without representing statistically significant departures.
Casualty comparison: The 12 fatalities in November 2025 represent substantially fewer casualties than many historical months. For comparison, November 2022 witnessed over 160 earthquake-related fatalities, while November 2016 saw minimal casualties. This variability reflects the stochastic nature of earthquake occurrence near vulnerable populations.
Seismological Research Insights from Recent Events
Recent major earthquake reports provide valuable scientific data advancing seismological understanding:
Rupture complexity: Preliminary analysis of the Vanuatu M7.2 earthquake by USGS finite fault modeling suggests rupture extended approximately 80 kilometers along the subduction interface, with peak slip of 2.5-3.0 meters. According to Lay et al. (2012, Annual Review of Earth and Planetary Sciences), such detailed rupture models constrain fault friction properties and stress distributions.
Stress triggering: Spatial-temporal clustering of earthquakes in several regions suggests stress transfer mechanisms. The Papua New Guinea sequence included events on multiple fault structures, potentially indicating triggered seismicity through Coulomb stress changes (Stein, 1999, Nature).
Deep earthquake mechanisms: Several deep earthquakes (depths exceeding 300 km) occurred in November 2025, particularly in the Tonga-Kermadec and South American subduction zones. These events provide insights into dehydration reactions and phase transformations in subducting slabs (Green & Houston, 1995, Annual Review of Earth and Planetary Sciences).
Aftershock productivity variations: The range of aftershock productivities observed across different tectonic settings contributes to understanding of fault zone properties and stress heterogeneity (Helmstetter & Sornette, 2002).
Global Seismic Monitoring Capabilities
The comprehensive documentation of major earthquakes in the past 30 days demonstrates remarkable advances in global seismological monitoring. According to Storchak et al. (2017, Physics of the Earth and Planetary Interiors), modern seismic networks achieve detection completeness for magnitude 5.0+ earthquakes exceeding 99% globally, with location accuracy typically within 5-10 kilometers for well-recorded events.
Key monitoring advances enabling comprehensive earthquake news this and last month include:
Expanded station coverage: The Global Seismographic Network (GSN) operates over 150 broadband stations worldwide, with regional networks adding thousands of additional instruments. This density enables rapid detection and precise location of earthquakes globally (Ekström et al., 2012, Physics of the Earth and Planetary Interiors).
Real-time data transmission: Satellite and internet connectivity enable near-instantaneous data sharing among seismological agencies, supporting rapid magnitude determination and tsunami warning (Kanamori, 2005, Annual Review of Earth and Planetary Sciences).
Automated processing: Machine learning algorithms and automated analysis systems generate preliminary earthquake parameters within 2-5 minutes of rupture, enabling timely public notification and emergency response (Meier et al., 2019, Science).
Crowd-sourced data: Systems like USGS “Did You Feel It?” and EMSC crowd-sourcing collect tens of thousands of felt reports for significant earthquakes, providing rapid intensity mapping and damage assessment (Bossu et al., 2018).
Earthquake Early Warning Systems Performance
Several regions with operational earthquake early warning (EEW) systems experienced recent M5+ earthquakes, providing opportunities to evaluate system performance:
Japan’s EEW system: Detected multiple magnitude 5+ earthquakes off the Japanese coast in November 2025, providing 5-25 seconds of warning to affected regions. According to Allen et al. (2009, Science), such warning times enable protective actions including automated train braking, elevator stopping, and industrial process shutdown.
California ShakeAlert: While no major earthquakes struck California during November 2025, the system continues operational testing and expansion, with full public alerting implemented across the state (Given et al., 2018, Annual Review of Earth and Planetary Sciences).
Mexico’s SASMEX: Provided warnings for moderate earthquakes along the Pacific coast, demonstrating continued effectiveness of one of the world’s longest-operating EEW systems (Espinosa-Aranda et al., 2009, Seismological Research Letters).
The absence of EEW systems in many seismically active regions, including Iran, Papua New Guinea, and Vanuatu, meant that populations received no advance warning before strong shaking arrived. Expansion of EEW capabilities to additional high-risk regions represents an important priority for earthquake risk reduction.
Building Code Performance and Vulnerability Assessment
Damage reports from November 2025 earthquakes provide insights into building performance and vulnerability patterns:
Modern engineered structures: Buildings designed to current seismic codes in Iran, PNG, and Vanuatu generally performed well, experiencing minimal structural damage even during strong shaking. This validates code provisions and demonstrates the effectiveness of earthquake-resistant design (Hamburger et al., 2004, Earthquake Spectra).
Unreinforced masonry vulnerability: Traditional construction without seismic reinforcement exhibited high damage rates, with collapse percentages of 15-40% in areas experiencing MMI VII-VIII shaking. This vulnerability pattern has been documented globally and represents a primary target for risk reduction efforts (Coburn & Spence, 2002).
Non-structural components: Even in buildings with minimal structural damage, non-structural elements including ceilings, partitions, and building contents experienced damage. According to Taghavi & Miranda (2003, Earthquake Engineering & Structural Dynamics), non-structural damage often accounts for 50-80% of total earthquake losses in modern buildings.
Landslide-induced damage: In Papua New Guinea’s mountainous terrain, earthquake-triggered landslides caused substantial damage to buildings and infrastructure. Keefer (1984, Geological Society of America Bulletin) documents that earthquakes magnitude 6+ in mountainous regions reliably trigger numerous landslides, creating distributed damage beyond direct shaking effects.
These observations reinforce the importance of continued building code enforcement, retrofitting of vulnerable structures, and land-use planning that accounts for secondary hazards including landslides and liquefaction.
Future Seismic Hazard Implications
The seismic activity in the past 30 days provides insights into ongoing tectonic processes and future earthquake potential:
Stress accumulation zones: Regions experiencing below-average seismicity may be accumulating stress for future larger earthquakes. According to Stein & Liu (2009, Nature Geoscience), seismic gaps along major fault systems warrant particular attention for hazard assessment.
Aftershock hazard: Regions affected by major earthquakes in November 2025 face elevated probability of damaging aftershocks for weeks to months. Probabilistic aftershock forecasting guides emergency management and public safety decisions (Reasenberg & Jones, 1989).
Triggered seismicity potential: Large earthquakes can trigger seismicity at substantial distances through dynamic stress transfer. The M7.2 Vanuatu earthquake potentially influenced stress conditions across the Southwest Pacific region (Parsons, 2005, Bulletin of the Seismological Society of America).
Long-term hazard assessment: Each recorded earthquake contributes data refining probabilistic seismic hazard models used for building codes, insurance, and risk management (Petersen et al., 2018, Seismological Research Letters).
Public Information and Risk Communication
The earthquake news this and last month demonstrates the critical role of effective risk communication. Seismological agencies worldwide have enhanced public information systems including:
Real-time notifications: Mobile apps and SMS alerts provide immediate earthquake information to affected populations, enabling rapid protective actions and situational awareness.
Social media engagement: Official agency accounts on Twitter/X, Facebook, and other platforms disseminate authoritative information, countering misinformation and rumors that often circulate following earthquakes.
Felt report systems: Interactive maps showing crowd-sourced shaking intensity help the public understand earthquake impacts and contribute to rapid damage assessment.
Educational content: Ongoing public education about earthquake preparedness, protective actions, and aftershock expectations enhances community resilience (Mileti & Peek, 2000, Natural Hazards Review).
According to Sutton et al. (2020, International Journal of Disaster Risk Reduction), effective risk communication during and after earthquakes significantly influences public response and can reduce casualties and economic losses.
Major earthquakes in the past 30 days demonstrate Earth’s persistent tectonic activity, with the largest earthquakes in November 2025 including a magnitude 7.2 event in Vanuatu, magnitude 6.8 in the Kuril Islands, and magnitude 6.5 in Papua New Guinea. Statistical analysis reveals 142 recent M5+ earthquakes and 18 magnitude 6+ events, slightly above long-term averages but within normal variability.
What were the largest earthquakes this month? The Vanuatu M7.2 represented the most powerful event, generating regional tsunami warnings and moderate damage. The Iran-Iraq M6.3 earthquake proved most destructive, causing 12 fatalities and substantial building damage in vulnerable communities.
Did any major earthquakes trigger tsunami warnings? Yes, the Vanuatu and Kuril Islands earthquakes generated warnings, with observed wave heights reaching 1.2 meters in Vanuatu. Effective warning systems prevented tsunami casualties.
Where can I find earthquake lists? The USGS earthquakes last month catalog and EMSC databases provide comprehensive lists of M5+ earthquakes this month with detailed parameters and impact information.
How many M5+ and M6+ earthquakes occurred? November 2025 recorded 142 magnitude 5-5.9 earthquakes and 18 magnitude 6+ events, demonstrating typical global seismicity patterns documented over decades of instrumental monitoring.
The recent major earthquake reports underscore the importance of continued investment in seismological monitoring, earthquake early warning systems, seismic building codes, and public preparedness programs. While November 2025 witnessed fewer casualties than many historical months, the Iran-Iraq and Papua New Guinea events demonstrate persistent vulnerability in regions with traditional construction and limited resources for earthquake risk reduction.
The largest aftershocks in November 2025 following major events demonstrated typical productivity patterns, with the Vanuatu sequence generating over 280 detected aftershocks M≥3.0. Continued monitoring and probabilistic forecasting support ongoing emergency management in affected regions.
The comprehensive global seismological network ensures that virtually all major earthquakes in the past 30 days receive rapid detection, precise location, and detailed characterization. This capability supports tsunami warning, emergency response, scientific research, and long-term hazard assessment that collectively contribute to earthquake risk reduction worldwide.
As tectonic plates continue their inexorable motion, future months will inevitably bring additional significant earthquakes. The lessons learned from November 2025 events—regarding building vulnerability, tsunami generation, aftershock behavior, and emergency response—inform ongoing efforts to mitigate earthquake impacts and protect vulnerable populations in seismically active regions globally.
