Gaua volcano (Vanuatu): increasing seismic activity

Mi, 14. Aug 2013, 14:58
14:58 PM | VON: T
A tendency of increasing seismic activity has been observed since June and GeoHazards keep a close eye on the volcano, which still remains at alert level 1 (on a scale of 4) for the moment. Areas within 3 km from the crater and the summit area should not be approached, today's new volcanic activity bulletin reads.
Satellite images show what is most likely a weak degassing plume from the volcano's main vent, Mt Garet on the shore of the caldera lake. The presence of the lake increases the risk of (usually sudden) phreatic explosions.
Ash emissions from Gaua were reported earlier this year in April based on satellite data, but had not been confirmed independently.
