Yasur volcano (Vanuatu) - Smithsonian / USGS Weekly Volcanic Activity Report for 20 October-26 October 2021 (New Activity / Unrest)

The Vanuatu Meteorology and Geohazards Department (VMGD) reported that seismic activity slightly increased at Yasur beginning at 1330 on 22 October. Emissions also increased and large, dense ash-and-gas plumes were visible rising from the crater in webcam images at 1445. Increased ash emissions were confirmed during field observations later that day, prompting VMGD to expand the restricted area to a 1-km radius around the cone, defined by Danger Zone B on the hazard map.
The Wellington VAAC noted that ash plumes rose as high as 1.2 km (4,000 ft) a.s.l. and drifted SE, E, and N during 22-24 October, based on webcam views and information from VMGD; emissions ceased by 1845 on 24 October. The Alert Level remained at 2 (on a scale of 0-4).
