Tungurahua volcano (Ecuador), activity update: powerful eruptions continue
Thursday May 26, 2011 07:29 AM |
Strong explosive activity continues at Tungurahua volcano in Ecuador, producing ash plumes of 1-3 km height, and causing significant ashfall in nearby areas and as far as 31 km downwind to the NW.
The is the summary from the Smithsonian/USGS Weekly Volcanic Activity Report 18-24 May:
"IG reported that on 17 May new fumaroles on Tungurahua's W flank, about 1 km below the crater, were observed from the Tungurahua Observatory (OVT) in Guadalupe (11 km N). Explosions during 17-23 May produced gas-and-steam plumes that rose to altitudes of 6-9 km (19,700-29,500 ft) a.s.l and mostly drifted SW, W, and NW. Ashfall was reported on most days in areas within 8 km SW, W, NW, N, and NNE, but reached as far as Guadalupe (11 km N), Ambato (31 km NW), and Penipe (15 km SW). On 17 May incandescence emanated from the crater. Blocks were also ejected from the crater, and rolled down the flanks, on 17, 19, and 21 May. Sounds resembling "cannon shots" were occasionally reported. Large windows vibrated on 21 May. Ash-and-gas plumes rose from the crater on 24 May and likely drifted W."
