Ubinas volcano (Peru): activity decreases
Activity has decreased since 23 April: less and generally smaller explosions have occurred since, with a possible pause during 23-25 April when webcam images show no plume during daytime.

However, during that time the volcano continued to produce an abundant degassing plume that sometimes contained some ash.
Ash emissions reappeared on 25 April, but remain weak compared to earlier this month.
A newspaper reported that seismic activity also decreased. Peruvian volcanologists seem to think that the low visible activity is due to a currently open-conduit system that allows for effective degassing of arriving magma, without creating overpressure needed to cause explosions.

A relatively strong ash emission was reported from last night (19:00 local time), inferred by seismic and infrared data. read all

The latest report by Peru's Institute of Geophysics (IGP) issued a series of recommendations to authorities, among which to raise the alert level to orange, given that activity has gradually increased and is now comparable to the eruption during 2006. ... read all

The volcano's activity increases. As more magma arrives to build up the new lava dome in the summit crater, more gasses are being released as well and cause near-constant explosive activity with moderately strong ash emissions at the moment (see video). ... read all

Ubinas volcano (Peru): increasing explosive activity with incandescent lava, preparations for evacuations
Activity at the volcano has been increasing over the past week, both the number and size of explosions and the corresponding seismic activity. Explosions on 9 April produced ash plumes that reached up to 3 km height, which is a significant increase compared to the smaller ones that had been occurring previously with 1.5-2 km tall plumes. Light ash fall occurred in areas to the NE, in areas up to 20 km distance including the villages Lloque, Chojata, and Ichuna. ... read all
