The number and magnitudes of earthquakes under Sierra Negra volcano in Galapagos, Ecuador are steadily growing since mid-2016. A significant uptick occurred on May 25, 2018, with 104 earthquakes within 24 hours. This, along with 'very important…
Ecuador's Fernandina volcano, the most active of Galápagos volcanoes, entered a new eruptive phase at approximately 17:25 UTC (12:25 local time) on September 4, 2017. The eruption comes after 8 years of superficial calm. It was observed by the crew of…
An international team of scientists showed an increasing volcanic danger on Cotopaxi volcano in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR). The Andes region in which Cotopaxi volcano is located is known to contain…
Seismic and deformation data indicate magma is trying to rise to the surface at Cerro Azul volcano in Galapagos, Ecuador. An eruption can be expected in the next few days or weeks, probably of the same type as those previously occurring at the volcano – the emission…
In a special bulletin released March 20, 2017, Ecuador's Institute of Geophysics reports a significant increase in activity under Cerro Azul volcano which might be a precursor to a new eruptive episode. Since 1932, there were 11 reported eruptions of the Cerro…
Ecuador's Instituto Geofisico (IG) reports a sharp increase in seismicity under the Cayambe volcano this month. It became more evident in the middle of June, but at the moment, the seismicity tends to decrease. The last known eruption of this volcano in 1786….
After an increase in seismicity since mid-April 2015, Ecuadorian volcano Cotopaxi finally erupted on August 14, 2015, for the first time since 1940. There were at least three eruptions registered on August 14, the first at 09:30, second at 15:15 UTC and third at 19:10
Ecuadorian Tungurahua volcano entered a new vigorous eruptive phase on Friday, April 4, 2014. A moderately strong vulcanian explosion occurred at 23:10 UTC and produced an eruption column rising several kilometers as well as small pyroclastic flows on the
A new eruptive phase has started at Reventador volcano in Ecuador, IGP reported. Increasing tremor was registered and steady ash emissions were observed on March 25, 2014. At night, incandescent blocks could be seen and heard rolling down from the crater
On July 16, 2013 IGEPN reported that in recent days Reventador volcano showed a significant increase in seismic activity accompanied by emission of a lava that descended down the southwestern flank of the cone on July 13.
Gas and ash emission was
