Wednesday Apr 11, 2012 20:08 PM | BY: T
The explosion ejected incandescent blocks to distances up to 500 to 600 meters below the crater rim on the northeast side. Seismically the explosion was followed by a signal of high-energy tremor that lasted about 40 minutes.
The explosion was heard in villages near the volcano and at the volcano Tungurahua Observatory (OVT), located 14 km north-west of the volcano.
From approximately 09:30 (local time) the energy and height of the eruption decreased significantly, and the height of the eruption column dropped to less than 1 km.
