A major eruption formed a new crater in 2000, and small eruptions occurred in 2012, 2013, and 2016. Air traffic controllers take special precautions when volcanic ash is present. For this sort of volcanic paroxysm, this was probably the actual worst-case scenario, says Shane Cronin, a volcanologist and Earth scientist at the University of Auckland.

Volcanic hazards White Island is one of several volcanoes in New Zealand that can produce sudden explosive eruptions at any time. The process took seven around-the-clock days and cost the city $5.4 million, often cited as an efficient and cost-effective example of ash cleanup. Some 22 people died. This volcanic debris can reflect incoming solar radiation and absorb outgoing land radiation, leading to a cooling of the Earths temperature.

That first trip was in 1990, Tait tells me, and, as it developed, Jenny and I were taking six people a day there. That can lead to gases getting trapped underneath, where they keep accumulating and getting heated, creating a pocket of superheated elements somewhat like a pressure cooker.

Ash can enter and disruptthe functioning of machinery found in power supply, water supply, sewage treatment, and communication facilities. In addition, the magmas path to the surface at this vent can get blocked, sometimes through the precipitation of minerals. How have animals adapted to the rainforest environment? When the pressure at the vent is released, a decompression wave rockets down into the volcanos throat, where it encounters more pressurized water. It was reported that there were 47 people on the island when the eruption occurred. White Island is monitored byGeoNetthe agency that operates New Zealand's geological hazard monitoring systems. Recent reconnaissance flights over the island, also known by its Mori name Whakaari, have found no signs of life.

You might wonder if this eruption triggered any changes, but it happened at night, with no witnesses, so it simply passed on by. Heavy rains mixed with the ash fall, collapsing the roofs of houses, schools, businesses, and hospitals in three different provinces. Sometimes, the shockwave hits the magma, turning what is a steam-based outburst into a magma-driven eruption. No matter where in the world they occur, no one has shown that they are able to forecast this kind of activity, Kilgour says. The Tonga underwater volcanic eruption rivaled the strength of the largest U.S. nuclear bomb and produced a "mega-tsunami" nearly the height of a 30-story skyscraper, a recent study finds.

How can the impacts of climate change be managed? In these cases, magma is shallow and the water and gas which is trapped below the surface affect surface and groundwater to form vigorous hydrothermal systems.
