The Tonga-Hunga Ha'apai volcano began to erupt on the 14th January 2022 and reached a powerful peak on the 15th January 2022. The eruption released massive amounts of ash and caused a tsunami, resulting in the potential inundation of areas across the region. In this assessment, four key Areas Of Interest (AOIs) have been identified and these are 1) Tongatapu, 2) Eua, 3) Ha’apai and, 4) Vava’u, based on the administrative boundaries from Global Administrative areas (GADM) to evaluate the exposure of cropland to ash cover.
