Tungurahua volcano news & eruption updates:
Tungurahua volcano (Ecuador) activity update
Thursday Jul 25, 2013 14:38 PM | DOOR: T
An increase in activity has occurred since yesterday. For 24 July, IGPEN reports an eruption column of steam and ash reaching 5 km above the crater drifting into westerly directions. During the past night, a further rise in activity has likely occurred, as the increasing tremor signal suggests.
This morning's seismic signal from Tungurahua (RETU station, IGPEN)
Weak to moderate explosion sounds could be heard overnight and ash fall was reported from El Manzano, Choglontus, Puela, Cahuaji, and in the sectors of Cevallos, Quero and Mocha.

Activity remains high. The volcano produces intermittent explosions and near continuous strombolian explosions and ash emissions that produce an eruption column reaching up to 1.5 km above the crater. Easterly winds drift the ash mainly to the west and SE, where light ash fall occurred in Cahuají and Choglontus. [meer...]

An increase of activity occurred yesterday. IGPEN recorded 3 strong pulses of volcanic tremor since midnight 20-21 July (local time), which were accompanied by strombolian activity and strong explosions that produced loud roars, heavy gunfire sounds, and vibrations that rattled floors, windows and doors of houses in areas nearby. Some were heard even in the Tungurahua Volcano Observatory (OVT), located 14 km north of the volcano. ... [meer...]

Activity both at the surface and internal remains at moderately high levels. Since the large vent-clearing vulcanian explosion on 14 July, the volcano has been producing strong strombolian activity and near-continuous ash emissions. ... [meer...]

After the strong vulcanian explosion on 14 July, the volcano calmed down first, but resumed activity on 16 July which has been characterized by ash venting and small to moderate explosions and is continuing. ... [meer...]

A large explosive eruption occurred Sunday (14 July) morning, producing a large ash plume that could be seen from Quito (135 km away) and pyroclastic flows. According to Washington VAAC, the ash reached altitudes of 45,000 ft (13 km). The eruption followed a fast build-up of seismic activity, and likely corresponds to a vulcanian-type explosion, where pressure builds up to eject a solid plug that has tapped the vent. Elevated seismic activity had been noted in phases at the volcano during the previous weeks and while not completely unexpected as a potential scenario, the strength of the explosion was a surprise. ...
