An ash-rich vulcanian eruption plume, viewed from the SE, rises above Sabancaya volcano in northern Perú on April 15, 1991. Strong vulcanian explosions were observed at intervals of 20-30 minutes during an April 13-19 visit to the volcano. The explosions lasted about a minute and produced 3-4 km high ash clouds. Explosive activity at Sabancaya began in May 1990 and was continuing in 1995.
