Tungurahua volcano (Ecuador): increasing activity with constant ash emission

Tungurahua volcano's activity is again increasing.
Starting at 07:10 local time on 9 April, a continuous tremor signal of high energy was detected and the volcano started to erupt a continous column of ash, which rose within few minutes to 2 km height and drifted to the south, and later increased to about 3 km height above the crater.
Constant rumbling noises, similar to turbines were reported.
Explosions occurred at 07:20 and 07:26 local time, with cannon-shot sounds and rumblings of blocks tumbling down the flanks of the volcano.
At 09:15 local time, black ash fall was noted in the southeastern sectors of the volcano such as in Palitahua, Capil and Toctes.
At the moment, the activity is mostly hidden in clouds and seems to continue at slightly lower intensity.
