(As one explanation of this unit, if all SO2 in the air column the satellite observed was flattened into a thin layer at the surface of the Earth at a temperature of 0° C, then 1 Dobson Unit would make a layer of pure SO2 0.01 mm thick.). Before dawn on August 29, Tavurvur – a stratovolcano on the island of New Britain, in Papua New Guinea’s eastern archipelago – awoke spectacularly after almost a decade dormancy. According to Herman Patia at RVO, a small pumice raft accumulated in Greet Harbor and pumice was still drifting about several weeks later. (The Real-time Seismic Amplitude is an often-used tool to summarize seismic activity during volcanic crises by presenting a measure of the average amplitude of ground shaking over successive 10-min intervals.). If a volcanic ash plume reaches a high enough altitude, the water content of that plume turns to ice crystals, and these ice crystals “white out” the ash content that would otherwise appear tan or brown.

A volcano eruption closed the airport for a day in 2006. Geologic Background. The density of ashfall was such that Tavurvur was obscured from all directions. According to Reuters news service the 7 October blast shattered windows up to 12 km from the caldera. An earlier caldera-forming eruption about 7100 years ago is now considered to have originated from Tavui caldera, offshore to the north. Figure 45 shows the ash cloud imaged from the MODIS satellite on 7 October 2006. Lava flows from Tavurvur cone have reached the sea. In 1994, a large eruption at Tavurvur and the nearby Vulcan peak destroyed much of Rabaul, covering the airport and much of the town with ash, and forcing the construction of a new capital, Kokopo, 20 km away. Ash was falling on Kokopo, causing power and phone cuts. The volcano erupted at 0845 am (local time) on 7th October 2006. A day later, the volcanic plume had dissipated. Herman Patia reported that by 28 October 2006 the eruption had quieted down with only occasional ash emission accompanied by rare explosions. here. The 1994 eruption produced simultaneous activity from the Vulcan and Tavurvur Volcanoes. The SO2 concentration-pathlengths on the figure are shown using the logarithmic scale of Dobson Units. The comparatively minor October 2006 volcanic eruption on the Papua New Guinea i sland of New Britain . The cloud subsequently dispersed over a broad western swath (N to W to S). Note that there were no anomalies for several months before this period. A major eruption triggered a tsunami that killed at least 420 people and injured 14,000 others. The bright “cloud” to the immediate left of the brown ash resembles a regular cloud but likely results from the volcano itself.
