Eruption column of Tungurahua's explosion on 11 April 2012
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.
