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.
If it erupted 25 times in the last 12,000 years, that is an average of once every 480 years. With the most recent eruption in 232, then it is “overdue” (these things are not anywhere near that regular) by about 1,300 years.
Even now, pools of water 30 miles away boil from the heat.
By definition, a super volcano erupts with 1,000 km3 (about 240 cubic miles – a cube of material over 6.2 miles on a side) of material ejected. An eruption like that will give us some “climate change” to deal with.
