Mayon volcano, Philippines: eruption 2018 (part 2, 25-27 Feb) - explosive activity

After a pause of 2 days with almost no ash emissions, mild explosive activity resumed on 24 Feb evening (but could not be well observed then due to heavy cloud cover). The lava flow activity continued with little changes, although seemed to decreased gradually during the days were were still there (until 27 Feb):

The "lava fountains", visually more similar to strombolian explosions, erupt from at least 2 different vents in the summit crater. This one ejects bombs to at least 2-300 m height. (Photo: Tom Pfeiffer)
