THEWATCHERS-Adonai Aug 20,2013
A submarine eruption at Mount Hobal, underwater flank of Iliwerung volcano, Indonesia, has occurred on August 19/20, 2013. VSI raised the alert level of Iliwerung volcano from 1 (normal) to 2 (watch) following increased seismic and visual activity from Hobal.
Iliwerung volcano forms a peninsula on the south coast of Lembata island, formerly Lomblen. Mount Hobal (Gunung Hobal) is located about 800 m from the coast.
A total of 181 earthquakes were reported at Hobal flank on August 19, 2013.
The latest bulletin of VSI issued on August 20 describes that the water around Hobal has recently shown significant color changes to yellow, intense bubbling and white steam plumes rising up to about 1000-2000 m from 07:14 local time on August 20 (22:14 UTC on August 19, 2013). Half an hour later, from 07:46 am, glow even began to be visible.
Strangely, no plume or other strong evidence of an eruption have been available so far from satellite data, except tiny spots visible on the latest images of the area which could be floating pumice (VD).
VSI points out that there is an elevated risk of tsunamis associated with potential more eruptive activity, and recommends not to approach the coast within 30 m from the sea. Visitors, fishermen and tourists are not allowed to engage in any activity within a radius of 2 km from the center of activity.
