Sabancaya volcano (Peru): likely false eruption report (ash plume reported yesterday)
Montag Aug 04, 2014 08:00 | VON: T
A pilot reported a volcanic ash plume to approx. 17,000 ft yesterday afternoon, which would infer that the volcano, which has been showing seismic unrest for a while, actually erupted. There are no other indications of an eruption and the ash plume was most likely a weather cloud.
Peru's geophysical institute reported in its latest summary on 1 Aug, that seismic activity continued at the volcano, but had decreased and mostly is tectonic in nature and lacks signature of magma moving (such as hybrid quakes). No thermal anomalies were detected at the volcano.
Only a degassing steam and gas plume show that the volcano is not completely calm.

Signs continue to show up that the volcano might be awakening: Peru's Geophysical Institute (IGP) who monitors the volcano has detected a slight increase in volcanic unrest recently. Both seismic and fumarolic activity at the volcano increased during the past 4 weeks (since 3 June). ... [mehr]
Sabancaya volcano (Peru): steaming and continuing earthquakes as possible precursors for new eruption
Mittwoch, Jun 18, 2014
According to local news, steaming at the volcano has been observed since yesterday morning and it is believed that the volcano could erupt in a near to medium term future: few weeks to months. ... [mehr]

Seismic unrest continued through Sep-Oct including occasional swarms of volcanic-tectonic quakes (such as on 10 Oct), but overall earthquake activity has been showing a slowly decreasing trend. The volcano remains to be closely monitored. [mehr]

Seismic activity has picked up. A number of earthquakes in the magnitude 2-3 range have appeared recently. [mehr]
Freitag, Jul 19, 2013
A strong seismic swarm has occurred during the past days under the volcano, culminating in a magnitude 5.9 earthquake on 16 July. The swarm consisted almost entirely of volcanic-tectonic quakes, that relate to rock fracturing due to rapid pressure changes and might be caused by an intrusion of magma. IGP reports that up to 1500 earthquakes were recorded per day. ... [mehr]
