One year ago today Hunga Tonga Hunga Ha'apai erupted, causing a devasting tsunami to reach the island. To help us better predict wave forms created by volcanic eruptions in future, a group of researchers have been mapping seafloor. New Zealand-based marine geologist Dr Marta Ribó tells Max what they've found.
