Copahue volcano (Chile): continuous weak ash emissions, crater glow
Wednesday Feb 03, 2016 10:37 AM | DOOR: T
Ash plume from Copahue yesterdayDuring the past weeks, the El Agrio crater has continued to emit weak, but near-continuous emissions of fine gray ash. Incandescence remains visible at night.
According to SERNAGEOMIN, this current activity, mainly phreatic, is caused by interaction of a small body of new magma interacting with the hydrothermal system at shallow depth.
Seismic activity, although above background, is relatively low as are other monitored parameters (e.g. deformation, SO2 output etc). No larger eruption is expected for the near future.
