Tungurahua volcano (Ecuador), activity update: decrease in activity since 24 February, 2012
Fri, 24 Feb 2012, 11:0511:05 AM | BY: T
From about midnight yesterday, 23 February, a decrease in several parameters of the activity of Tungurahua volcano is reported by Ecuador's Instituto Geofísico who closely monitor the volcano.

Seismic tremor has decreased, no noises were reported nor new ash fall, suggesting that no new eruptions have taken place, although visible observations are difficult due to frequent cloud cover.
Whether this is only a short break in activity or an end of the current eruptive phase is unknown. The last notable eruption was recorded last night at about 18h00 local time, and consisted in a strong strombolian-to-vulcanian type ash explosion ejecting incandescent bombs to up to 500 m height above the crater and to about the same lateral distance in all sides, showering the upper flanks with glowing ejecta, especially the upper northwestern and western flanks.
