4 days ago · There are two volcanoes in the area: Nea Kameni, an islet within Santorini’s caldera; and Kolumbo, a submarine volcano about 8 kilometers (5 miles) northeast of Santorini. Last week, Greece’s Climate Crisis and Civil Protection Ministry announced that sensors had picked up “mild seismic-volcanic activity” inside the caldera.

Santorini is a volcanic island on the Hellenic Volcano Arc, an area of intense seismic activity. The island's cliffs were formed by a massive eruption 3,500 years ago.

Although dormant, Santorini is an active volcano. Numerous minor and medium-sized, mainly effusive, eruptions have built the dark-colored lava shields of Nea and Palea Kameni inside the caldera. Their last eruption was in 1950, and now only fumarolic activity, primarily inside the recently active craters, takes place. [ 2 ]
