After several months of calm, the volcano started to erupt yesterday morning again. An initial moderately strong explosion produced an ash plume that rose 2.5 km above the volcano and drifted SE to the Ubinas valley, where approx. 1.5 mm of ash fall occurred in 6 km distance.
The explosion was followed by continuous ash emissions of varying intensity, accompanied by strong volcanic tremor. A significant increase in seismic activity had already been noted by the Observatorio Vulcanológico del Sur (OVS) since 22 March this year, so the new eruption, probably caused by a new batch of magma arriving at the vent, didn't come as a bit surprise to the monitoring volcanologists.
People in areas to the SE of the volcano are advised to wear dust masks, and protect water storages.
