Ambrym volcano (Vanuatu): activity update
Thu, 27 Aug 2020, 18:3618:36 PM | BY: MATTHEW
Since the last update, activity at Ambrym is continuing at the low unrest level Volcanic Alert Level 1. Some volcanic hazards do remain on Ambrym specifically at the summit and eastern part of the Island. These are related to the presence of cracked areas. In addition to the summit hazards, the presence of active rifts and faults (major ground cracking) at the South-East area of Ambrym are also hazardous, they will continue to be eroded and affected by earthquake activity.

The danger zone at the summit area remains limited inside the Permanent Exclusion Zone at Benbow and Danger Zone A at Marum (See Ambrym caldera safety map). These danger zones are about 1 km around Benbow and 2 km around Marum craters including Maben-Mbwelesu, Niri-Mbwelesu and Mbwelesu. An additional danger zone at the South-East of Ambrym remains within 500 meters from major cracks. The lava lakes that used to appear in Benbow and Marum craters have disappeared since the December 2018 eruption. The remaining activity inside both craters consists of ongoing steam emissions.
Open cracks in the South-East Ambrym that formed during the December 2018 eruption may continue to open due to erosion. Major earthquake activity could continue to affect these cracks and weak layers or areas around the actives craters.
