Momotombo volcano (Nicaragua): strong explosion this morning

The cone of Momotombo volcano covered by glowing bombs from this morning's eruptionA strong explosion occurred this morning at 04:22 local time at the volcano, covering much of the summit cone with incandescent ejecta.
The lava flow effusion and continuous strombolian activity had stopped in early December, followed by only high-temperature degassing, sporadic minor explosions and the growth of what might have been a small lava dome. A more intense phase of activity seems to have started yesterday. Early on 2 January, small ash emissions occurred, followed by more, still weak explosions in the early afternoon of yesterday.
The strong explosion this morning might have involved a small pyroclastic flow on the NE side of the volcano, reaching about 1.5-2 km length.
Whether or not this activity is sign of a new batch of magma arriving at the vent, and leading up to more intense activity to come, or result of more superficial processes, e.g. surface pressure released beneath the recently emplaced lava occupying the summit is unclear.
No damages were reported to have occurred from this morning's explosion.

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]

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. ...

It seems that the volcano continues to erupt and might have been intensifying its activity with now near-continuous explosions. ... [details]

A series of at least 4 small explosions occurred at the volcano this morning, at 07:49, 08:17, 08:42, and 08:55 local time. The eruptions, in particular the last and largest one, produced steam and ash plumes that rose up to approx. 1 km from the summit. ... [details]

The volcano remains restless. A small earthquake swarm started this morning under the northern flank of the volcano. ... [details]
