Robot boat mapping giant opening of underwater volcanic bigger than Tongatapu

The January eruption of Hunga-Tonga Hunga-Ha’apai and the subsequent tidal wave caused devastation in Tonga and killed people as far away as South America. The atmospheric shockwave caused by the eruption was felt as far away as the UK.

Kaniva News reports the robot boat, the Maxlimer, is based in Tonga, but will return to the site of the volcano to complete the survey of the opening, known as a caldera.
