The massive eruption, larger than the one on 14 January, generates an enormous amount of energy. Research carried out by the Alaska Volcano Observatory in collaboration with the Alaska Satellite Facility used mathematical modeling based on satellite imagery to determine that this recent increase in seismic activity had been caused by the upward thrust of moving magma deep under the earth's surface. The Hunga Tonga-Hunga Ha'apai volcano erupts again at 5.10pm local time on Saturday 15 January. showed magma moving deep below the Mount Fuji-shaped volcano. Mutual Fund and ETF data provided by Refinitiv Lipper. We still think the magma is very deep. These occur without warning and typically generate small clouds of volcanic ash that are a hazard in the immediate vicinity of the volcano, though more significant ash emissions are possible. . The fact that the explosion happened beneath the sea likely contributed to the explosiveness, but not how far the sounds traveled, Fee said. Previous eruptions of Pavlof indicate that the level of unrest can change quickly and the progression to more significant eruptive activity can occur with little or no warning.
