A pyroclastic flow sweeps down the floor of the Tar River valley on the eastern flank of Soufrière Hills volcano on January 16, 1997. The Tar River Estate house, which had been damaged by earlier eruptions, is the white dot on the ridge at right center. The January 16 pyroclastic flow was the largest to date during the eruption. The pyroclastic flow traveled about 3.5 km into the sea beyond the new delta formed at the mouth of the Tar River valley.
