Caldera
Rabaul is one of the most active volcanoes in Papua New Guinea, and one of its most dangerous. It is located on the north eastern end of New Britain Island, and is the eastern most volcano in the Bismarck arc.
The caldera has an elliptical form (14 x 9 km) and is surrounded by a steep volcanic ridge several hundred meters high. The present shape of the caldera was caused by two periods of collapse. The first was between 500-600 AD. The second

Rabaul has had major eruptions 3500 and 1400 years ago. An eruption of Rabaul in 1994 destroyed Rabaul city, the largest town on New Britain Island. Eruptions severly affected Matupit Island in 2008-09, forcing most of the population to relocate to safer areas.
Eruptive ents in Rabaul Caldera include; Turanguna, Tavurvur, Rabalanakia, Sulphur Creek, Kombiu (mother), and Beehives.
Seismicity at Rabaul volcano
Earthquake activity at Rabaul caldera increased in 1971 and continued for 23 years before the volcano finally erupted in 1994. This example that shows seismic activity can be used as an indicator of future activity, but cannot predict the timeframe.
