• Very strong explosion at Colima, ash up to 7 km (23 000 feet) a.s.l.

    A very strong explosion occurred at Mexican Colima volcano at 13:45 UTC on January 25, 2017. This is yet another strong explosion at the volcano, currently one of the most active in the world. The eruption was accompanied with pyroclastic flows on the NE flank. The…

  • Bogoslof ejects ash more than 9.5 km (31 000 feet) a.s.l., Alaska

    Alaskan Bogoslof volcano erupted again at about 22:20 UTC on January 18, 2017, following an approximately 20-minute-long increase in seismic activity. The cloud it ejected is presumably more ash-rich than others in current eruptive sequence. Alaska Volcano…
