Volcanologist Richard Robertson of the Montserrat Volcano Observatory makes precision leveling measurements on the west flank of Soufrière Hills volcano on August 19, 1995. Measurements such as these enabled scientists to track the progress of the eruption. The boulders in the foreground are on the surface of pyroclastic-flow deposits from previous eruptions. Gage's Mountain lava dome forms the peak at the right.
