A new and intense episode of eruptive activity started at Tungurahua volcano, Ecuador, on February 1, 2014. A new paroxysm was observed along with a series of powerful vulcanian explosions. Ash plume surpassed 13 km (40 000 ft); eruption produced heavy tephra fall and pyroclastic flows up to 8 km in length.
This intense activity was accompanied by a significant release of rubble that was earlier perceived in Pillate, Capil and Palictahua. Ash in areas surrounding the volcano caused total darkness in the Chacauco.
Tungurahua started showing signs of increased activity from the early hours of last Thursday with explosions of moderate size and significant ash emissions.

The last eruptive phase of Tungurahua occurred between October 6 and November 13, 2013. It consisted of 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 November 13, 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.
