However, the current ongoing seismic activity near Santorini, at least as of February 7, features thousands of earthquakes, many with magnitudes ranging between 4.0 and 5.0.
And local scientists monitoring Santorini have reported no change to indicate the current seismic activity is a forerunner of another Santorini eruption.
Earthquake swarms are often associated with fluid movement in the earth’s crust and the resulting seismic activity is usually less dramatic than the sudden movement of a strong mainshock.
Global observations of earthquakes tell us that only a small fraction (about 5%) of earthquakes are foreshocks to larger earthquakes.
Greece’s government has just declared a state of emergency on the island of Santorini, as earthquakes shake the island multiple times a day and sometimes only minutes apart.
