Greece has declared a state of emergency on Santorini after hundreds of undersea earthquakes shook the resort island for nearly a week.

NBC News’ Matt Bradley reports on the aftermath and public response to several days of near constant earthquakes around the tourist hotspot of Santorini, Greece.

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

Earthquakes are still rattling Greece’s volcanic island of Santorini every few minutes as authorities bolster their emergency plans in case the hundreds of temblors in recent days are a harbinger of a larger quake to come.

The seismic activity at Santorini and other Greek islands is not over and the biggest quake has not happened yet, a seismologist has warned, CNN reported.Remy Bossu, Secretary-General of the European-Mediterranean Seismological Centre,
