A new analysis of Tonga eruption's seismic activity

Tokyo, Jan 28 (PTI) A new analysis of seismic data recorded after the massively violent eruption of the underwater volcano Hunga Tonga-Hunga Ha'apai, on January 15, 2022, consisted of two distinct sequences of events, according to a new study.

Kotaro Tarumi and Kazunori Yoshizawa at Hokkaido University, Japan, discussed their methods and findings in an article in Earth and Planetary Science Letters.

"We showed that the eruption consisted of two distinct sequences of events, some of which occurred quasi-periodically in the first sequence. It will be worthwhile to investigate the mechanisms involved in such eruption cycles further," said seismologist and geophysicist Yoshizawa.
