Violent Supervolcano Appears to Be Rumbling Back to Life

A supervolcano has had its alert level increased in the wake of 700 earthquakes occurring nearby. Taupō volcano, which is a supervolcano situated underneath New

Zealand's largest lake, Lake Taupō, had its Volcanic Alert Level (VAL) increased from 0 to 1 on September 20. Level 1 indicates minor volcanic unrest, according to GeoNet, a

geological hazard agency in New Zealand. Lake Taupō sits within the giant caldera of a supervolcano on New Zealand's North Island, roughly six miles above the magma

chamber. The volcano has erupted 25 times in the last 12,000 years, most recently in the year A.D. 232, resulting in the largest and most violent eruption on Earth in the past

5,000 years. The Volcanic Alert Level for Taupō Volcano has been raised to Volcanic Alert Level 1 (minor volcanic unrest). This minor unrest is causing the ongoing

earthquakes & ground deformation at the volcano. Read our bulletin with all of the information here: https://t.co/T9yTR3aF32 pic.twitter.com/FD31y9iYqD— GeoNet (@geonet)

September 20, 2022 Supervolcanoes, which also include Yellowstone, Long Valley in eastern California and Toba in Indonesia, are volcanoes that erupt with magnitude 8 or

greater on the Volcano Explosivity Index, which means that deposits of the eruption are spread further than 240 cubic miles. According to GeoNet, more than 700 earthquakes

have been recorded beneath Lake Taupō in 2022, with an increase in the frequency of these earthquakes being seen since May, at depths between 2.5 and 8 miles beneath the lake.
