What kind of volcano is スフリエール山（セントビンセント）?

スフリエール山（セントビンセント） is classified as a Stratovolcano in Saint Vincent and the Grenadines. Its tectonic setting is Subduction zone / Oceanic crust (< 15 km).

How is seismicity near スフリエール山（セントビンセント） monitored here?

Earthquakes within 50 km of the crater are aggregated from 18 seismic networks and checked against a swarm rule that compares the current rate with this volcano's own 30-day background. Ash advisories come from the VAAC centres that are connected.

1902年5月7日の噴火では約1,600人が亡くなりました。近くのマルティニーク島でプレー山がサン・ピエールを壊滅させる前日のことです。2021年4月、数か月にわたる溶岩ドームの成長を経て再び噴火した際には、最初の爆発の前に約2万人が避難を命じられ、犠牲者は出ませんでした。
