Manam volcano (Papua New Guinea): large explosive eruption sending ash plume to 45,000 ft altitude

An large eruption seems to have occurred this morning around 05:30 GMT from Manam volcano north of New Guinea. VAAC Darwin reported an ash plume rising to 45,000 ft (approx. 14 km) altitude.
A hot spot is visible on MODIS satellite data. For the moment, no precise other information about the nature of the eruption is available, as the island is remote and most of its population had been relocated after the last major activity in 2004.  Volcano Watch
