Ubinas volcano (Peru): hot spot at crater
mardi mars 04, 2014 12:12 | AUTEUR : T
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.

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. ... lire toutes

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. lire toutes

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. ... lire toutes

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. ... lire toutes
