Greece’s government declared a state of emergency on Santorini on Thursday after hundreds of undersea earthquakes shook the resort island for nearly a week. The ministry of civil protection’s announcement will provide authorities faster access to state resources.

Past tsunamis have hit Israel’s coast, and with Santorini’s seismic activity at an all-time high, the risk of another wave is being taken seriously. Authorities remain on high alert, as the region watches and waits to see what happens next.

Greece has declared a state of emergency on Santorini after a series of earthquakes shook the popular tourist island this week and prompted more than 10,000 residents and workers to evacuate.
