According to CENAPRED on May 11, 2013 during the last 24 hours the volcano monitoring system recorded 53 exhalations of low and moderate intensity, accompanied by emissions of steam, gas and ash sometimes. Also two explosions occurred of moderate magnitude, one at
When an eruption of the volcano happens below a glacier, a subglacial volcano can be formed. These subglacial volcanoes, called tuyas, can enable scientists to piece together details on how the climate of our planet has changed over the course of its history. The

Philippine Institute of Volcanology and Seismology (PHIVOLCS) stated in the latest advisory report that Mayon volcano (13.2500°N, 123.6833°E) produced a small phreatic eruption early on May 7, 2013, which lasted 2 minutes 26 seconds. The agency stated that in
The current eruption of Cleveland Volcano, which began with an explosion on May 4, 2013, has transitioned into a continuous low-level eruption. The activity is characterized by long duration airwave signals measured on the nearby Okmok seismic network, 120 km (80
Alaska Volcano Observatory (AVO) infrasound detected 2-3 possible explosion at Cleveland Volcano early on May 4, 2013. The infrasound signals suggest that this was a relatively short duration, low-level explosion. A small, low-altitude ash cloud along with high

The National Secretariat for Risk Management said yellow alert remains in surrounding communities of Tungurahua volcano in Ecuador.
On April 27, 2013 two small earthquakes associated with fracturing of rocks within the volcano (volcano-tectonic earthquakes) were
Strong strombolian activity and frequent ash emissions that continued throughout the whole night on April 27, 2013, were a prelude to the 13th paroxysm (lava fountaining) of this year at Etna’s New Southeast Crater. The strombolian activity had begun already on
