Scientists reveal what triggered Santorini 'earthquake swarm'
Summary
Scientists have figured out that the swarm of earthquakes near Santorini was caused by molten rock moving through an underground channel. They used physics and artificial intelligence to analyze over 25,000 tremors. The earthquakes were linked to magma moving beneath the surface, but researchers believe the activity has now settled down.Key Facts
- A swarm of over 25,000 earthquakes occurred near the Greek island of Santorini.
- Scientists used physics and artificial intelligence to study the cause.
- The earthquakes were due to magma moving through a 30km underground channel.
- The magma moved horizontally about 20km through the Earth's crust.
- The volume of magma involved could fill 200,000 Olympic-sized swimming pools.
- The research team created a 3D model to map the seismic activity.
- The seismic activity started in January 2025 and included many earthquakes over magnitude 5.0.
- The activity appears to have settled as the magma cooled deep in the Earth's crust.
