Ubinas volcano (Peru): hot spot at crater

MODIS hot spot at Ubinas volcano (ModVolc, Univ. Hawaii)
MODIS hot spot at Ubinas volcano (ModVolc, Univ. Hawaii)
According to the Geophysical Institute of Peru (IGP), magma has arrived near or at the crater of the volcano. This is indicated by a recent swarm of hybrid earthquakes and a weak thermal anomaly that has been detected at the summit during the past 3 weeks.
In a press article, the head of IGP, Orlando Macedo, said that that based on the low energy of the seismic signals recorded, the quantity of new magma that has risen is estimated to be small and that the most likely scenario for the near to medium future are smaller (explosive) eruptions from the volcano.

Seismic activity at Ubinas during 14 Feb and since 31 Jan (IGP)
The volcano could be in the process of entering a new eruptive phase. Two small (likely phreatic) explosions occurred last Friday at 13:46 and 14:45 h local time (18:46 and 19:45 GMT), ejecting plumes of ash and steam rising approx. 1.5-2 km. A strong sulfur smell was noticed in up to 5 km distance. ... read all

Seismic swarm on 25 Jan 2014 (IGP)
Two small earthquake swarms occurred in January, the latest bulletin of the Peru's Geophysical Institute (IGP) reports. The first one happened between 8-9 Jan, and the second and stronger one on 25 Jan. In addition, bluish degassing (SO2, an indicator of the presence of magma) was observed. read all

Seismic signal from Ubinas 18 Sep (UB2 station, IGP)
While the volcano has calmed down at the surface since the series of 9 phreatic explosions during 1-5 September, a pulse of volcanic tremor yesterday could indicate that the volcanic crisis is not over or even still at the beginning. ... read all

Ash explosion from Ubinas yesterday (INGEMMET)
New eruptions occurred at the volcano. It seems more and more likely that the phreatic explosions are a result of new magma rising from depth, and the volcano could be heading towards more sustained and possibly larger magmatic activity in the near future. ... read all
