Reventador volcano (Ecuador): new eruption

The volcano has entered a new eruptive phase since yesterday, Ecuador's Institute of Geophysics (IGP) reported. Starting from 15:00 local time yesterday, increasing tremor was registered and steady ash emissions were observed. At night, incandescent blocks could be seen and heard rolling down from the crater where probably a new lava dome has started to appear.
Small pyroclastic flows descended on the eastern, southeastern and southern flanks of the volcano, probably as a result of re-mobilization of fresh lava and tephra deposits. These so-called secondary pyroclastic flows reached lengths of 500 m below the summit.
IGP assumes the most likely scenario for the evolution of the new eruptive episode is that activity continues at similar levels for a while. So far, lava avalanches and pyroclastic flows have been confined within the caldera, near the flanks of the main cone. So far, no reports of ash falls became available from communities in the nearby areas, suggesting that the eruption is still small. An important hazard remains in the form of lahars (mud flows), which can be generated by re-mobilization of loose material during heavy rainfall and would most likely threaten the bed and banks of the Quijo river.

Explosion and small pyroclastic flow from Reventador on 2 Nov 2013
The activity consisting of sporadic small to moderate explosions continues but has decreased after 2 November. On that day, a small pyroclastic flow descended on the west flank of the active cone, reaching a length of 300-400 m. Explosions produced plumes of up to about 2 km height and light ash fall occurred in San Rafael village located 8 km east of the volcano. ... read all
