Greek authorities have closed schools and deployed emergency crews as a swarm of earthquakes intensifies near the volcanic island of Santorini. Scientists aren't expecting Santorini or other volcanoes in the region to erupt, but they warn more powerful earthquakes could be coming.
People on Santorini began feeling tremors last week as a cluster of underwater earthquakes broke out beneath the Mediterranean's Aegean Sea. These small earthquakes — mostly magnitude 3.5 or less — continued to intensify on Monday (Feb. 3).
