Galunggung Volcano, western Java, Indonesia (7.25°S, 108.05°E). All times are local (GMT+7 h). Intermittent explosions from Galunggung began April 5 (see June 1 Eos), destroying about 90% of Gunung Jadi, the lava dome extruded into Galunggung's large breached summit crater during the last eruption in 1918. Lahars and nuées ardentes flowed southeastward through the breach onto the upper portion of the major prehistoric landslide deposit. The highest reported ash column reached 16.5 km, pitting the windshield of a passing airplane. Ash fell as far away as the Yogyakarta-Solo area, about 300 km to the east.
