Benbow crater is the main residual active centre of the large ancient volcano which has formed Ambrim Island. For the eleven months preceding December 1951 it has been the source of extraordinarily intense and prolonged explosive activity. The volume of ash and scoria ejected during this period exceeds 800,000,000 cubic metres. Evidence has been found during the recent inspection of this volcano that suggests that the current phase of explosive activity has ended. The 1950-1951 eruption, possibility of future activity, and effects of the eruption, are discussed in this report.
