Momotombo volcano (Nicaragua): explosion triggers pyroclastic flow

Another explosion occurred at the volcano yesterday at 10:40 local time. It produced a pyroclastic flow that descended the NE flank through the prominent ravine that also had channeled the recent lava flow from 2015.
The pyroclastic flow, surrounded by yellow-brown ash, was likely the result of collapse of older material at the crater during the explosion. Whether and in which proportion fresh magma is involved in the current activity is difficult to say without an analysis of the ash.
Glow continued to be visible at the crater during the night, suggesting that temperatures have increased and maybe magma is now at least close to the vents.

Activity at the volcano continues, but at lower intensity than during the first days of the new eruption. Strombolian explosions at the summit crater accompany the emission of a steam-ash plume rising up to approx. 1000 m, an possibly still continued, but very weak lava flow extrusion. ... [details]

mercredi, déc. 02, 2015
As this morning's webcam images already had suggested, a new fully-blown magmatic eruption is now in progress at the volcano: pulsating lava fountains (or continuous, strong strombolian activity) feed a new lava flow that slowly descends on the NE side of the volcano, and a dense ash plume that rises approx. 2-2.5 km above the volcano and drifts NW. ...
