Smithsonian Institution Global Volcanism Network Bulletin v. 20, no. 10, October 1995 Rabaul (Papua New Guinea) Minor seismicity and vapor emission Rabaul New Britain, Papua New Guinea 4.27S, 152.20E; summit elev. 688 m All times are local (= GMT + 10 hours) The volcanoes at Rabaul Caldera continued to remain quiet in October. Tavurvur~s summit area released bluish white vapors at very low rates; however, the emission rates rose during rainy days at the end of the month. No emissions came from Vulcan. Only 19 earthquakes were recorded in October. Two of the 13 low-frequency earthquakes originated from Tavurvur while the rest came from either within or just outside the caldera~s N sector. The six high-frequency earthquakes took place on the 20th (2 earthquakes), 23rd (2), 26th (1), and 29th (1). Most of these high-frequency earthquakes occurred in the caldera~s NE sector (Namanula area). One high-frequency earthquake (ML 1.9, on the 23rd) originated near Tavurvur at about 1 km depth. October ground deformation remained very low. Information Contact: same as for Manam.
