Santorini Earthquakes: Scientists Discover Magma Ascent Cause
Imagine the ground shaking a lot on Santorini.
Scientists wanted to know why.
They found that a lot of hot, melted rock called magma was moving up from deep inside the Earth.
This magma pushed up towards the island, causing many earthquakes.
They used special tools and AI to track the magma's path, which helped them understand how the earthquakes happened.
The magma broke the rocks and formed paths.
This also explains why Santorini had another big earthquake with a tsunami in 1956.
Now, they know that the shifting of microplates can cause volcanic activity and lead to earthquakes in the area.
Scientists analyzed a series of earthquakes near Santorini, Greece.
Over 28,000 earthquakes were recorded in early 2025.
The earthquakes were caused by magma rising from deep in the Earth.
Magma began rising in July 2024, leading to increased seismic activity.
The study used data from earthquake stations and instruments placed near the Kolumbo volcano.
