It is als known as Rejo te Kvachi, "Kavachi's Oven", and one of the most active of the Pacific with near surface eruptions every few years that often build temporary islands. New islands were formed at least 9 times since its first recorded eruption during 1939. The new islands formed were not large enough and coated with solid lava flows to be able to resist wave erosion. They were submerged again after a few months after each eruption. The frequent shallow submarine eruptions that sometimes breach the surface produce surtseyan activity, magma-water explosions that eject jets of steam, ash, and incandescent bombs above the sea surface. On some occasions during such eruptions, the vent was sealed sufficiently to produce liquid lava spattering and lava flows on the temporary islands.

It is likely that some volcanic activity has continued intermittently at the undersea volcano after a discolored water plume was first spotted on 29 January this year. Although no further signs of activity were visible on clear days after the first sightings, satellite images from 21 March and 8 May, compiled by Culture Volcan, showed again significant plumes originating from the volcano. This suggests that activity (if any) has been occurring in short-lived pulses rather than continuously. Actualités précédentesdimanche, févr. 02, 2014 What could be a small steam plume above the submarine volcano is visible on the latest reasonably clear satellite image from 12 hours ago. It does not look as if the volcano has breached the surface (yet).
[details]samedi, févr. 01, 2014 A submarine eruption is likely occurring at the submerged volcano. A NASA satellite image from 29 Jan shows a plume of discolored sea water swirling and drifting from the location of the volcano. The discoloration is likely from suspended volcanic sediments (the fragmented lava) and gasses. ...

[details]Plus sur VolcanoDiscovery: Krakatoa explodes: In the afternoon of 17 Oct, a particularly violent explosion occurred at Anak Krakatau, blasting away a portion of the southern crater rim. A similar event might have been the final trigger for the catastrophic landslide that let the cone collapse and cause a devastating tsunami on 22 Dec 2018.  Ibu volcano photos: Ibu in Halmahera is one of the most active, but rarely visited volcanoes in Indonesia. A spectacular lava dome is growing inside the volcano's breached crater, with frequent explosions. |
