A swarm of hybrid earthquakes started at 1:10 am today (Tuesday) and is still continuing. There were 53 hybrid earthquakes during this period.
Good views of the dome above Galways Wall yesterday showed new material is rapidly filling the 11th of April scar and that rockfalls are filling in the chute in the wall. Pyroclastic flow deposits are filling in the deeper parts of the White River Valley. Approximately 10m or 30 feet of new material were deposited and has covered the Great Alps Waterfall completely.
Visibility is very good this morning and there is a little steam around the summit. The GPS readings show very little change on the western side of the volcano.
The volcano remains active and dangerous, with a very large dome which could collapse at any time. People should exercise extreme caution and remain vigilant at all times. Ash levels are high and everyone is urged to wear their dust masks in ashy areas.
