Santorini caldera is a large, mostly submerged caldera, located in the southern Aegean Sea, 120 kilometers north of Crete in Greece.Visible above water is the circular Santorini island group, consisting of Santorini (known as Thera in antiquity), the main island, Therasia and Aspronisi at the periphery, and the Kameni islands at the center.
The Minoan eruption was a catastrophic volcanic eruption that devastated the Aegean island of Thera (also called Santorini) circa 1600 BCE. [2] [3] It destroyed the Minoan settlement at Akrotiri, as well as communities and agricultural areas on nearby islands and the coast of Crete with subsequent earthquakes and paleotsunamis. [4]
Nea Kameni is a small, uninhabited Greek island of volcanic origin located in the Aegean Sea, within the flooded Santorini caldera.Nea Kameni (new burnt) and the neighbouring small island Palea Kameni (old burnt) have formed over the past two millennia through repeated eruptions of dacite lava and ash.
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.
Similar volcanic activity had been recorded in 2011, when it lasted for 14 months and ended without any major issues. Another volcano — a submarine one called Kolumbo — lies about 8 kilometers (5 miles) northeast of Santorini, nearer to the epicenter of the current earthquakes. But seismologists say the quakes aren't related to the volcanoes.

There are around 200 volcanoes in Texas that have been extinct for millions of years, making them unlikely to erupt again, because the volcano no longer has a magma supply. It could however be ...
