The Extinction Protocol

December 31, 2012COLOMBIAMild ash explosions continue to occur sporadically at the volcano, such as recently seen on 29 Dec. For the month of December, this is the 6th time ash emissions were observed (although more could have occurred and gone unnoticed during times of bad weather). In comparison, there have been 2 emissions observed in November, 12 in October, and 5 in September. The volcano’s last major eruption occurred in 2010. –Volcano Discovery

The increase had been detected on June 24, 2012 and since that date, 6891 earthquakes have been recorded, i.e. an average of 150 quakes per day. Most of them (5177) are of very small magnitude, but the remaining 1714 quakes were of significant energy (local magnitudes 0.1-2.2) and concentrated in an area between 0.1 and 5 km northeast of the volcanic summit at depths between 2 and 6 km. None of these events were felt by inhabitants of the communities surrounding the volcano Sotará. The deformation network shows a possible inflation process towards the northeast sector of the volcano, which correlates with the epicentral zone of seismicity reported and suggest that magma is rising there, and might (or might…
