View of New Guinea Volcano as seen from STS-64

STS064-116-055 (20 Sept. 1994) --- Near the end of its mission, the crew aboard space shuttle Discovery was able to document the beginning of the second day of activity of the Rabaul volcano, on the east end of New Britain. On the morning of Sept. 19, 1994, two volcanic cones on the opposite sides of the 6-kilometer sea crater had begun to erupt with very little warning. Discovery flew just east of the eruption roughly 24 hours after it started and near the peak of its activity. The eruption, which sent a plume up to over 60,000 feet into the atmosphere, caused over 50,000 people to evacuate the area. Because winds were light at the time of the eruption, most of the ash was deposited in a region within 20 kilometers of the eruption zone. This photo shows the large white billowing eruption plume is carried in a westerly direction by the weak prevailing winds. At the base of the eruption column is a layer of yellow-brown ash being distributed by lower level winds. A sharp boundary moving outward from the center of the eruption in the lower cloud is a pulse of laterally-moving ash which results from a volcanic explosion. Geologists theorize that the large white column and the lower gr
