Yellow Alert Issued Sudden ash eruption yesterday at Lascar volcano in Chile
Ash plume from Lascar yesterday
An moderately strong ash eruption occurred at the volcano yesterday morning at 09:32 local time. An ash plume rose approx. 2.5 km from the summit crater.
It is unclear whether the eruption was caused by fresh magma or, more likely, by an explosion of overheated water (phreatic activity).
There had not been any particular indication of new activity. According to SERNAGEOMIN’s routine reports, seismic activity under the volcano, dominated by earthquakes related to internal fluid movements, had been progressively decreasing during the past months, from a total of 207 in May to 62 events in September.
The alert status of the volcano was raised to “yellow” and in the coming weeks, it will be monitored more closely.
