An ash plume rising above Iya is seen from Ende city on 27 January 1967. Iya erupted suddenly with no recognized precursory activity. The plume rose 5 km above the summit from a new 400-650 m wide crater on the upper SW flank, accompanied by a pyroclastic flow. Houses were damaged on the nearby island of Ende and one person was killed. Secondary lahars later caused another fatality in a village below the ash-covered cone of Raja. The eruption ended on 30 January.
