A smaller eruption in Tonga’s Hunga Tonga-Hunga Ha’apai (HTHH) volcano may have primed it for the massive explosion that happened in January this year, revealed a new study.
The smaller eruption may have sunk the volcano’s main vent under the surface of the ocean, priming it for the massive explosion a day later, triggering a tsunami and sending plumes of gas, dust, and ash 36 miles into the sky, suggested the research, published last week in the journal Earthquake Research Advances.
