PVMBG reported that at 0018 on 21 March an event at Agung was recorded for 1 minute and 47 seconds by the seismic network. Weather conditions prevented visual observations of the summit. The Alert Level remained at 3 (on a scale of 1-4) with the exclusion zone set at a 4-km radius.
Geological Summary. Symmetrical Agung stratovolcano, Bali's highest and most sacred mountain, towers over the eastern end of the island. The volcano, whose name means "Paramount," rises above the SE rim of the Batur caldera, and the northern and southern flanks extend to the coast. The summit area extends 1.5 km E-W, with the high point on the W and a steep-walled 800-m-wide crater on the E. The Pawon cone is located low on the SE flank. Only a few eruptions dating back to the early 19th century have been recorded in historical time. The 1963-64 eruption, one of the largest in the 20th century, produced voluminous ashfall along with devastating pyroclastic flows and lahars that caused extensive damage and many fatalities.
