In recent weeks, seismologists using the GeoQuake app have recorded an increase in seismic tremors near the island of Rhodes. While these minor earthquakes may seem harmless at first glance, they often precede more significant seismic events.
According to calculations using the Seismic Entropy Method (SEM), there is an elevated risk of a strong earthquake (magnitude ~7.0) in the Aegean region between May and July 2025.
What Is the Seismic Entropy Method?
SEM is an analytical tool that assesses seismic risk based on the dynamics of regional seismic activity. It evaluates the entropy — or disorder — in the spatial and temporal distribution of earthquakes, offering a comprehensive overview of ongoing tectonic processes.
Key Factors Increasing Earthquake Risk:
- Seismic swarm (Jan 25 – Feb 6, 2025): A series of small to moderate tremors signaling crustal stress accumulation.
- Earthquake on May 13, 2025 (M6.0) in the Aegean Sea — a significant event that may precede a stronger one.
- Ongoing tectonic energy build-up along the active faults of the Aegean region.
Why SEM Deserves Attention
Unlike traditional forecasting methods that focus on specific fault lines, SEM analyzes the broader seismic picture. It considers both recent and long-term geophysical trends, making it a valuable early-warning tool for earthquake-prone areas.
Rhodes: A Seismically Vulnerable Region
Rhodes, one of Greece’s largest and most visited islands, lies close to the boundary between the African and Aegean tectonic plates. Its location places it at high risk from seismic events. Historically, powerful earthquakes have impacted its urban structures and infrastructure.
Unlike major quakes, frequent microseismic events are common in this region. While not directly harmful, they often indicate stress redistribution in the Earth’s crust. Ignoring them could lead to dangerous consequences. GeoQuake monitors these changes in real time and provides early warnings to help people prepare.
Potential Earthquake Hazards on Rhodes:
- Damage to historic landmarks, including the UNESCO-listed Old Town
- Disruption of electricity and water supplies
- Localized tsunamis in coastal areas
- Threats to tourists in resort zones
What You Can Do — GeoQuake Safety Recommendations:
- Stay updated with alerts via the GeoQuake app
- Prepare an emergency kit and evacuation plan
- Keep ID documents and a means of communication with you
- Learn the location of safe zones in your area
Earthquakes can’t be prevented — but their impact can be minimized.
GeoQuake gives you real-time data and trend analysis to help you act early and stay safe. Whether you’re a resident or tourist, installing GeoQuake and enabling notifications can make all the difference.
