Tungurahua volcano (Ecuador) activity update: intermittent explosions, decreasing activity

Thursday Aug 23, 2012 10:05 AM | BY: T

Current seismic signal this morning from RETU station (IG)
Current seismic signal this morning from RETU station (IG)
Tungurahua's activity has been decreasing since yesterday, which is also visible on the seismograms. Weak explosions could be heard occasionally, but visual observations were impossible due to cloud cover.
Previous news
Wednesday, Aug 22, 2012
IG reported that on 15 August three small explosions from Tungurahua were detected along with continuous tremor. An ash plume rose 1 km above the crater and drifted W, producing ashfall in El Manzano (8 km SW) and Pillate (7 km W). Activity increased the next day, characterized by increased tremor, roaring sounds, and instances of vibrating windows. An ash plume again rose 1 km, drifted W, and produced ashfall in El Manzano and Pillate. On 17 August two long periods of tremor associated with emissions were detected; 10 explosions were also recorded. Periodic clear views of the crater showed continuous steam-and-ash plumes rising 1.5-3 km above the crater and drifting WNW. Ash fell in Pillate and Bilbao (8 km W). Activity significantly increased at 2100, and strong explosions were detected. Cloud cover prevented visual observations. ... [more]

Tungurahua's eruption continues. This morning, a tall ash plume was rising to 32,000 ft (ca. 10 km) altitude and drifting west. A slight decrease in tremor is visible on the latest seismograms. ... [more]

Tuesday, Aug 21, 2012
The volcano continues to emit a near constant steam and ash plume rising on average 1.5 km with peaks of up to 4 km above the crater. This activity produces significant ash fall in areas west of the volcano such as Sabañag, Santuario, Hualcanga Santa Anita, Jaloa la Playa, Pillate, Hierbabuena, San Juan and other rural areas of Quero, Cevallos, Tisaleo and Mocha. ...

Pyroclastic flow deposit from the evening of 18 Aug (IGEPN)
Monday, Aug 20, 2012
The eruption continues with constant steam and ash emissions generating a plume 1.5 km above the crater, intermittent cannon-shot-like explosions of moderate strength, which eject blocks of considerable size, and pyroclastic flows reaching 1.5 km distance. During 19 Aug, 4 pyroclastic flows were counted that went towards the areas of Cusúa and La Pirámide. ... [more]
