Wally Johnson and Neville Threlfall re-examine the explosive
volcanic eruptions that in 1937–43 killed more than 500 people in the Rabaul
area of East New Britain, Papua New Guinea. They reassess this disaster in light
of the prodigious amount of new scientific and disaster-management work that has
been undertaken there since about 1971, when strong tectonic earthquakes shook
the area. Comparisons are made in particular with volcanic eruptions in
1994–2014, when half of Rabaul town was destroyed and then abandoned. A striking
feature of historical eruptive periods at Rabaul is the near‑simultaneous
activity at Vulcan and Tavurvur volcanoes, on either side of Rabaul Harbour.
Such rare 'twin' eruptions are interpreted to be the result of a
common magma reservoir beneath the harbour. This interpretation has implications
for ongoing hazard and risk assessments and for volcano monitoring in the
area.
