Tungurahua Volcano: New eruption

A new eruptive phase has begun at the volcano. Since the early morning today, the seismic network detected an increase in earthquakes including signals of small explosions and long-period events and tremor typical for internal fluid movements (gasses and magma).
The Tungurahua volcano Observatory while unable to make direct visual observations received reports from observers that fine black ash fell in Pungal and Penipe, and minor amounts in Palictahua. The black color of the ash suggests that it originates from fresh (so called juvenile) magma.

The last eruptive phase of Tungurahua was between 6 Oct and 13 Nov past year and consisted in strombolian-vulcanian explosions generating ash columns rising up to 4 km, accompanied by strong shock waves and producing occasional pyroclastic flows. Bursts of moderate to strong intensity tremor characterized seismic activity during that period.

Since 13 Nov, activity had decreased markedly and the volcano only showed weak degassing and no signs that could have been interpreted as precursors to the current new activity, IGPEN mentions in its latest bulletin.

This implies that the magma that started the current new phase of activity has risen very quickly from a deeper reservoir into the shallow plumbing system of the volcano. In other words, eruptions at Tungurahua can start with little or even no warning.

Tungurahua erupts 3 times on Saturday
Ecuador’s Tungurahua volcano erupted 3 times last Saturday prompting the evacuation of local villages.

Ecuador’s Geophysics Institute reports that two moderate explosions on Saturday were followed by a third of greater size, and pyroclastic flow stretched 500 meters down its flank. The eruption created a 8 kilometre column of ash above the volcano, which is located 135 kilometres southeast of the capital, Quito.

Tungurahua is a 5023m high stratovolcano and is one of South America’s most active volcanoes. Since 2000, a new lava dome has been growing in its summit crater.

Vulkaan Ecuador spuwt aswolk van tien kilometer
De vulkaan Tungurahua in Ecuador is vrijdag tot uitbarsting gekomen. De vuurberg spuwde as en heet gesteente tot tien kilometer de lucht in. Dat heeft het geofysische instituut van Ecuador gezegd.

De eerste uitbarsting duurde vijf minuten, gevolgd door een tweede, die vier minuten aanhield, en vijf geringere bevingen.

De vulkaan van ruim vijf kilometer hoog kwam op 1 februari tot leven. Een derde van de provincies van het Latijns-Amerikaanse land wordt getroffen door de uitbarstingen. Een regionaal vliegveld sloot uit voorzorg de deuren.

Is dat gezien vanuit Baños of vanuit Riobamba?

Ik heb er in 2007 nog overheen gelopen, hij rommelde en rookte toen alleen wat.
