Tungurahua volcano (Ecuador): moderate explosion on 26 Feb and small pyroclastic flows
dimanche mars 02, 2014 09:54 | AUTEUR : T
The volcano had a short burst of activity on 26 Feb, producing a series of moderate explosions and small pyroclastic flows reaching up to 400 m on the northern and northwestern flanks. Ash plumes rose up to 2.5 km above the crater. Since then, the volcano has been mostly quiet and only had minor emissions.

IGPEN reported continuing inflation at the top of the volcano since 15 Feb as well as long-period type earthquakes, which could indicate influx of gasses and magma in this area of the volcanic edifice.

Activity continues an overall decreasing trend. The volcano has occasional explosions and ash emissions, typically 4-5 per day, which cause light ash fall, mostly in Pillate, Tisaleo and El Manzano to the S and SW. In between such emissions, the volcano is calm. Seismic activity is still significant, but also seems to be decreasing, the latest IGPEN report mentions. ... lire toutes

Activity remains at moderate to high levels according to the Geophysical Institute (but is considerably lower than earlier this year). Occasional explosions produce ash plumes of approx 1-2 km height and light ash fall was reported from the Pillate sector yesterday. ... lire toutes

Overall, the volcano's visible activity has continued to decrease with fewer and weaker explosions, although seismic activity remains moderate to high. The strongest explosion in the past days was one yesterday evening that produced an ash column rising 3 km, a powerful cannon-shot explosion sound. Bombs fell around the crater at distances of 500 m. ... lire toutes

After the major eruptions on 1 Feb, the volcano continued to produce frequent (comparably) smaller explosions of strombolian to vulcanian type, sometime causing small pyroclastic flows. Ash falls have been mainly affecting areas in Penipe, south of the volcano. During the past days, activity has been decreasing overall. ... lire toutes

Activity of the volcano remains intense, but the style of the eruption has changed towards near continuous ash emissions as opposed to discrete, but potentially much more violent explosions. The ash plume still rises up to 4 km above Tungurahua's summit at times. lire toutes
