Eruption of Momotombo volcano this morning (from TN8 Nicaragua video)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.
Light ash fall was observed in the community of El Papalonal and near the Momotombo geothermal plant to the SW of the volcano.
This marks the first eruptive activity of the volcano in 110 years, the last confirmed eruption of Momotombo having been back in 1905. Since 1524, the volcano has known 16 recorded eruptions, most of them small, probably phreatic explosions. Larger eruptions occurred in 1605 and 1609, when explosions ejected larger bombs and blocks to considerable distances,- reportedly they fell in the area of the now abandoned town of León Viejo approx. 6 km west from the volcano.
The volcano has been showing seismic unrest during the past few years already with frequent shallow earthquakes occurring in the area.
A team of volcanologists from INETER has arrived to take samples of the ash, gasses and monitor the volcano more closely. Armando Saballos from INETER ruled out that the explosion from this morning is likely to have any relationship with the currently increased activity phase of nearby Telica volcano.
