REPORT OF THE STATE OF THE VOLCANO TUNGURAHUA No. 332
Wednesday, November 28, 2007SUMMARY OF THE ACTIVITY OF THE VOLCANO
The activity of the Tungurahua volcano continues to present an upward trend with the generating a high number of explosions and long-period earthquakes. All explosions have caused constant columns of steam and ash, creating continuing decline of the same the area around the volcano, particularly in the western and south western flank. During the night it was observed brightness in the area of the crater and expulsion of incandescent blocks that fell in
senior flanks of the volcano to about 500 m below the rim of the crater. For these circumstances seismic activity index is at high level and with increasing tendency. This kind of activity could be extended for a few more days, so it’s necessary careful observation and continuing to define what is the most likely scenario.ANNEX TECHNICAL AND NOTES
Seismicity: There were 72 events long period (LP), 33 events tremor emission and 128 explosions. The largest explosion occurred at 7h 49 and produced the vibration of windows in localities around 13 km from the volcano and a column of ash 1.5 km high.
Ash / Programs / Brightness: From sectors of Apple, Vazcún, Choglontus, Bilbao and Cotaló
falling ash reported during the night and early morning hours today, in the course of this day
there are no further reports of falling ash. During the night was observed brightness intense and incandescent in the crater, reporting that blocks filmed by all flanks of the volcano up to 500 meters below the level of the crater. The explosions today generated columns of steam
charge moderate ash reaching heights of up to 2 kilometers, please contact the west.
Weather / rain / Lahares: Most of the time the sector of the volcano remains good climate.
