Tungurahua volcano news & eruption updates:

Tungurahua volcano (Ecuador): continuing unrest, small explosions

Intermittent mild explosive activity with ash emissions continues at the volcano.
An unusual seismic swarm occurred during the night of 9-10 April, following two volcanic earthquakes at 6 km depth in the evening. More than 1300 quakes were recorded until noon of 10 April. What made it unusual was that the seismic events were of the "drumbeat" type, not seen on Tungurahua during the past 16 years, but thought to correspond to the ascent of viscous magma.
Gas emissions have continued to show an increase and the presence of black ash also suggests that a new batch of magma is arriving. These observations make the scenario of a sudden violent explosion in the near future a serious possibility.
Authorities have started to take preventive measures in case of a larger eruption. Road conditions and meeting points in case of evacuations were checked and communicated to the local population. Access restrictions were imposed to potentially dangerous areas, in particular valleys draining from the volcano and the road Penipe Los Pajaros - Banos.
