EXPERT REACTION: How the magma plumbing under the Hunga volcano changed after the eruption

Embargoed until: Publicly released:

NZ, Tongan, and US researchers modelled the changes to the magma plumbing system under Hunga volcano before and after its massive explosion at the start of 2022. Before the eruption, magma was located in three separate reservoirs. Afterwards, researchers found two of these reservoirs had become connected and their volume decreased by 30% due to the eruption, which may have contributed to the collapse of the inner part of the volcano.
