According to wikipedia, a Surtseyan eruption is a type of volcanic eruption that takes place in shallow seas or lakes. It is named after the island of Surtsey off the southern coast of Iceland.
Such eruptions are commonly phreatomagmatic eruptions, representing violent explosions caused by rising basaltic or andesitic magma coming into contact with abundant, shallow groundwater or surface water.
This video of the volcanic eruption at Anak Krakatau was captured by Sylvie Loison on September 18, 2019.
Back in December 2018, the peak collapse of Anak Krakatau triggered a tsunami that killed more than 420 people.
