Activity at the volcano has remained at the same level during the past 24 hours. Another swarm of volcano-tectonic earthquakes was recorded during the early morning today. A few small rockfalls were also recorded during the period but no views of the crater were possible.
Nineteen volcano-tectonic earthquakes occurred between 00:08 and 06:44 this morning. These were located at less than 2 km beneath the crater area. Five small rockfall signals were recorded during the period. Intermittent broadband tremor was recorded on the Gages seismic station from the beginning of the reporting period until 04:32 today.
The viewing conditions have been very poor today, and no observations or EDM measurements were possible. A GPS survey on the eastern flank of the volcano was completed today. The results from this survey are currently being processed.
Processing of the COSPEC measurements conducted during the past two days has been completed. These show sulphur dioxide flux of 449 tons/day on 23 October and a relatively high value of 1519 tons/day on 24 October.
The volcano remains in an active and highly dangerous state. Further activity, possibly leading to an explosive event could occur with little warning in the near future. Everyone who enters the evacuated zone must remain alert and be ready to move at short notice. Individuals who go beyond the Long Ground area into the Tar River valley are risking death.
