All times are local (unless otherwise noted)


PVMBG reported that white plumes from Agung rose as high as 500 m above the crater rim during 1-7 November. The Alert Level remained at 3 (on a scale of 1-4), and the exclusion zones remained at 6 km, with an additional expansion to 7.5 km in the NNE, SE, S, and SW directions.

Geologic Background. 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 caldera rim of neighboring Batur volcano, 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.
