GoKawiilNew sonar data explains why 2022 Tonga volcanic eruption produced an unusual tsunami
Scientists compared sonar seafloor mapping taken before and after the 2022 Hunga Tonga-Hunga Ha'apai eruption, revealing physical changes to the underwater volcano that help explain the tsunami it triggered. The eruption's tsunami behaved differently from typical earthquake-generated waves, prompting researchers to investigate its distinct origin.
