Scientists have detected several thousand earthquakes, the vast majority of them with small magnitudes, in just over two weeks near Greece's volcanic island of Santorini, the University of Athens' crisis management committee said Tuesday,

Residents on the popular island of Santorini have experienced thousands of earthquakes this month while researchers have revealed a new magma chamber growing underneath the Kolumbo submarine volcano.

Santorini has been hit by the strongest earthquake in weeks. A 5.3-magnitude quake struck in the sea area between Santorini and Amorgos in the Cyclades - the strongest of the thousands detected last week.
