Sabancaya volcano (Peru): seismic unrest and ground deformation

The possible ash emissions on 9 May have not been confirmed, but unrest in the form of increased earthquake activity and ground deformation has increased since early May, the Geophysical Institute of Peru (IGP) reported in its press release on 10 May.
So-called "hybrid" earthquakes (related to both the fracturing of rock and fluid movements) have increased since 2 May, while purely volcanic-tectonic quakes have remained stable.
Satellite-born InSAR radar measurements showed that the area of the current seismicity (north-east of the volcano, just above the village of Hornillo), has shown subsidence of about 7 cm, which is possibly related to magma draining from there into different reservoirs.

Numbers of earthquakes at Sabancaya over the past weeks (IGP)
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
