Scientists from the Rabaul Volcano Observatory and the U.S. Geological Survey observe an eruption plume from Tavurvur volcano on 4 October 1994, while conducting deformation measurements on Matupit Island. This location was a tilt site where repeated measurements of uplift or subsidence were made during the course of the eruption. The pit at the lower right was excavated to study ashfall deposits from the eruption.
