The first four months of the eruption involved intense earthquake swarms and vigorous steam explosions, caused by rapid heating of the groundwater by rising magma. Its eruption in 1902 was the third most deadly in historic time. Dome growth recommenced two weeks after the explosive eruption on 17 September 1996. With actionable Earth observations, the NASA Earth Science Applied Sciences Program empowerscommunities across the world to find solutions to the challenges they face every day. The explosions and collapses of the volcano modified the island topography especially in the Tar River Valley on the southeastern side of the island, where pyroclastic flows have gouged a deep canyon. By late-1996, as magma effusion rates escalated, most seismic events were originating within a volume about 2 km diameter which extended up to the surface from only about 3 km depth - the diminution of shear failure earthquakes suggests the pathway for magma discharge had become effectively unconstricted.
