The volcano has remained quiet, but is still showing signs of unrest. IGP scientists found evidence of eruptive activity (no fresh lava or pyroclastic deposits) inside the crater of of the volcano during a helicopter survey on 21 May. Only steaming and degassing were observed from the crater, that measures about 300-350 m in diameter and is 200 m deep.
2 major fumarolic areas are present in the N and SW sectors of the crater floor. Seismic activity is currently calm (as of 27 May), but occasional earthquake swarms still occur (such as on 21 May). Overall, a rise of volcano-tectonic quakes, likely related to new magma intrusions at depth, have been on the rise since early May.

Seismic activity has decreased at the volcano, the latest press release of IGP shows. It seems less likely now that the volcano will produce an eruption soon,- as in many cases, an intrusion has happened at depth without (so far) breaching the surface (= erupting). ... read all
