Roundup of Global Volcanic Activity
Sinabung (Sumatra, Indonesia): The eruption, characterized by slow extrusion of viscous lava, continues well into its second year. During the past days, incandescent avalanches, but also explosions (from pressurized gas-rich magma) have occurred, producing small to moderate ash plumes rising up to 2-3 km.
Dukono (Halmahera): Ash emissions from the volcano continue to be intense and near continuous. A plume extending 100 nautical miles (180 km) to the east was reported this morning (Darwin VAAC).
