M4.9 Earthquake Strikes 28 km SE of Fry, Greece

Seismologists have recorded a magnitude 4.9 earthquake in Greece, with the epicentre located 28 km SE of Fry, Greece. The event occurred at 08:25 UTC on Wednesday, June 24, 2026 and originated at a depth of 10.0 km.

Seismic Context for Greece

Greece and the broader Aegean region are among the most seismically active areas in Europe, positioned along the Hellenic Arc where the African Plate subducts beneath the Eurasian Plate.

Greece accounts for approximately 50% of all seismic energy released in Europe. The Ionian Islands, Crete, and the North Aegean are historically the most active zones, though significant earthquakes can and do occur across the entire country.

About This Event

At a focal depth of 10.0 km, this is classified as a shallow earthquake (0–70 km). Shallow events are typically the most damaging: the seismic energy has less distance to travel before reaching the surface, resulting in stronger and more abrupt ground shaking at the epicentre.

In terms of felt effects, a magnitude 4.9 earthquake is typically felt strongly by everyone; minor to moderate damage possible in vulnerable buildings. Moderate earthquakes are felt by virtually everyone near the epicentre. Strong shaking lasting 10–30 seconds can topple unsecured items, crack plaster, and cause poorly anchored objects to fall. Aftershocks are common following moderate events.

Understanding the Magnitude Scale

Earthquake magnitude is measured on a logarithmic scale — meaning each whole-number increase corresponds to roughly 32 times more energy released and approximately 10 times greater ground motion amplitude. A magnitude 4.9 event therefore releases significantly more energy than its number alone might suggest to the casual observer.

A magnitude 4.9 earthquake releases approximately approximately 30,000 tonnes of TNT — comparable to the Hiroshima atomic bomb of energy. For comparison, this exceeds the energy released by most conventional explosive events and is sufficient to shift tectonic stress in measurable ways across a wide region.

Significant damage can occur to vulnerable structures — particularly unreinforced masonry, old adobe buildings, and poorly maintained older construction. Well-engineered modern buildings are designed to withstand this level of shaking with minimal structural impact, though contents may shift and non-structural elements (ceilings, partitions) can be damaged.

What to Do After an Earthquake

Keep an earthquake emergency kit accessible at home. It should include at least 72 hours of water (4 litres per person per day), non-perishable food, a first aid kit, torch, battery-powered radio, copies of important documents, and essential medications. Reviewing and restocking this kit annually is strongly recommended.

During and after an earthquake, follow instructions from official civil protection, emergency services, and government authorities. Avoid spreading unverified information on social media. Official channels provide the most reliable information about aftershock risk, evacuation orders, and available assistance.

Staying Informed

The Greek Earthquake Planning and Protection Organisation (OASP/EPPO) provides guidance and resources for residents. Standard Drop, Cover, Hold On procedures apply, and coastal residents should move inland immediately after strong shaking.

Building Codes and Earthquake Resilience

One of the most effective tools against earthquake damage is modern building codes that specify how structures must be designed and constructed to withstand seismic forces. Countries with active fault zones have developed increasingly sophisticated seismic design standards over the past 50 years. However, the gap between modern code-compliant buildings and older existing structures remains a critical challenge in earthquake risk reduction worldwide. Building retrofit programmes and public awareness campaigns are key components of any national earthquake preparedness strategy.
