The turquoise-colored crater lake of the Cráter Activo of Rincón de la Vieja is seen here on April 2, 1998 from its eastern rim during a quiet period of the 1998 eruption. The eruption began with phreatic explosions during February 15-18 that produced steam plumes up to 2 km above the crater lake and scorched vegetation on the NE side of the crater. On February 16 a mudflow traveled up to 12 km down the Penjamo and Azul rivers. Twenty explosions were recognized from seismic records, and additional explosions were recorded in May, June, and September.
