GNS Science volcanologists raised volcanic alert to Level 2 (minor eruptive activity) and the Aviation Color Code to Orange level (volcanic eruption is under way with no or minor ash emission) after discovering a spiny lava dome at White Island volcano in an existing
Another ash explosion with plume rising up to 3 km occurred at 12:10 local time today, December 11, 2012 followed by a smaller one at 12:41 and 13:16 local time on active Indonesian volcano Lokon.The first explosion was relatively violent and produced a plume rising
