Momotombo volcano (Nicaragua) - Smithsonian / USGS Weekly Volcanic Activity Report for 24 February-1 March 2016 (Continuing Activity)
INETER reported that during 19 February-1 March explosions at Momotombo were detected daily; 88 explosions were detected during 1 December 2015-1 March 2016. Explosions produced ash plumes, and ejected incandescent material onto the N, NE, E, and SE flanks. Ash plumes rose 1.7-2.3 km above the crater and drifted SW during 21-22 February; gas-and-ash plumes rose 1.8 km on 24 February; an ash plume rose 1 km on 25 February; and a small gas-and-ash plume rose 300 m on 26 February.

A pyroclastic flow traveled 3.5 km down the N and NW flanks during 23-24 February. Explosions on 27 February ejected tephra 300 m above the crater. At 0646 on 1 March explosions ejected gas and incandescent tephra; an ash plume rose 1.2 km and drifted W and SW.
The gas-and-ash emissions lasted 16 minutes, causing the plume to widen and darken the sky.

Activity at the volcano has been increasing. During the past days, explosions have become frequent, with intervals of only few hours. The largest on Wednesday evening at 20:50 local time showered almost the cone with incandescent ejecta and produced ash plumes up to 1 km tall. Unconfirmed reports suggest that some of the eruptions also have produced small pyroclastic flows. ... Read all
