Part 2/9:
The USGS has reported that the recent surge in earthquakes near the Santorini Caldera is significant. Although earthquake swarms can sometimes be harmless, they often serve as precursors to volcanic activity. The frequency and depth of these quakes are being closely examined, as they could indicate the movement of magma beneath the surface. Scientists are particularly vigilant, recalling similar instances in the past, like the 2011-2012 earthquake swarm, which resulted in noticeable ground deformation—a clear warning that volcanic pressures were building below.
