Ubinas is Peru's most active volcano. A small, 1.4-km-wide caldera cuts the top of the volcano. The steep-walled, 150-m-deep summit caldera contains an ash cone with a 500-m-wide and 200 m deep crater Debris-avalanche deposits from the collapse of the SE flank of Ubinas about 3700 years ago extend 10 km from the volcano. Widespread plinian pumice-fall deposits from Ubinas include one of Holocene age about 1000 years ago. Holocene lava flows are visible on the volcano's flanks, but historical activity, documented since the 16th century, has consisted of intermittent minor-to-moderate explosive eruptions.

News from Ubinas volcano:
Ubinas volcano (Peru): no significant change in activity since the last update; descent of a lahar detected
Saturday Mar 21, 2020 16:45 PM | BY: MARTIN
Traveled lahar down the SE flank from Ubinas volcano on 18 March(image: IGP)
IGP reported that the warning system at the volcano detected the
decrease of a lahar (volcanic mud flow) of a low volume that traveled downslope in SE direction through the Volcanmayo ravine due to the streams that run through this sector. This is located 2 km away from the Ubinas town.
The population is recommended to stay away from the streams and avoid Querapi-Ubinas-Huarina highway.

IGP reported that the seismic station records internal tremor associated with the descent of a lahar (mud flows) of a moderate volume.
The lahar which formed
traveled down the SE flank of the volcano along the Volcanmayo gorge at the approx. distance of 2 km from the Ubinas town. ...
