More than 25,000 earthquakes rattled the Greek islands earlier this year, sending residents fleeing and prompting tourists to reconsider their vacation plans. According to a new AI-powered study, the pulsing movement of a massive underground magma pool was behind the mysterious earthquake swarm.

The international study, led in part by scientists from University College London (UCL) and published Thursday in the journal Science , used artificial intelligence to analyze the seismic data from between Santorini and nearby Amorgos . Researchers found that the tremors were not the result of a typical fault slip but were instead caused by rebounding sheets of magma slicing through the Earth’s crust about 7 miles (12 kilometers) below the seafloor. This deep magma activity triggered burst
