Ash plume from this morning's eruption at Gamalama volcano (image: Leopold Kennedy Adam @LeopoldAdam / twitter)
: A new eruption occurred at the volcano this morning at 07:53 local time. An explosion produced an ash plume that rose approx. 1.5 km above the summit and drifted NE and dispersed quickly. The Ternate airport was temporarily closed.
