Steam rises from the surface of a hot secondary lahar in the Temas river on 19 May 1966, three weeks after a devastating eruption on 26-27 April. During the eruption lahars reached 31 km down the Temas river to the SW. The Temas river lahars were part of the main flow that originated in the Badak river channel below the southwestern low point of the crater rim. Primary lahars caused most of the more than 200 fatalities from the eruption, but three people were also killed by secondary lahars such as the one seen in this photo.
