Ubinas volcano (Peru): activity continues to decrease

The current eruptive phase might be approaching an end. Since the second half of April, visual and seismic activity at the volcano have been decreasing. Explosions and ash emissions have almost ceased, although there are still some occasional bursts.
IGP released a report showing the evolution of seismic activity over the past weeks. It shows that hybrid earthquakes (indicators of rising magma) increased until 5 April and then started to drop. Surface activity in turn increased until 13 April and remained elevated until 19 April. This suggests that the magma took approx 8 days to reach the surface from its deeper source.
One of the strongest explosions occurred on 19 April, when large bombs were ejected to up to 2.7 km distance. After this explosion, which might have destroyed the lava dome in the crater, the volcano showed abundant degassing and ash venting, probably a result of the cleared conduit.
