Volcanoes known to have Surtseyan activity include: Surtsey, Iceland. The volcano built itself up from depth and emerged above the Atlantic Ocean off the coast of Iceland in 1963. Initial hydrovolcanics were highly explosive, but as the volcano grew, rising lava interacted less with water and more with air, until finally Surtseyan activity ...
Volcanic eruptions that rated 7 on the volcanic explosivity index.Such eruptions release a tephra volume of at least 100 km 3 (24 cu mi) with devastating long-term effects on the surrounding area and profound short-term effects on global climate.
Augustine Volcano (Alaska) during its eruptive phase on January 24, 2006. A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
An animation of the earthquake swarm from the start until 19 September. An earthquake swarm started under Cumbre Vieja on 11 September 2021. It slowly migrated to the surface, with earthquakes of up to around mb Lg magnitude 3.5, [24] [25] and more than 22,000 earthquakes were recorded in the space of a week. [26]
Active volcanoes such as Stromboli, Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear. Some dangerous volcanoes in "populated areas" appear many times: Santorini six times, and Yellowstone hotspot 21 times.
A diagram of a destructive plate margin, where subduction fuels volcanic activity at the subduction zones of tectonic plate boundaries. In 1841, the first volcanological observatory, the Vesuvius Observatory , was founded in the Kingdom of the Two Sicilies . [ 1 ]

For example, the Parícutin volcano erupted continuously between 1943–1952, Mount Erebus, Antarctica has produced Strombolian eruptions for at least many decades, and Stromboli itself has been producing Strombolian eruptions for over two thousand years. The Romans referred to Stromboli as the "Lighthouse of the Mediterranean".
