Overview

• On August 1, two explosive eruptions at Mount Lewotobi Laki-Laki sent ash plumes to about 11 km at 12:48 UTC and 19.2 km at 17:05 UTC, according to PVMBG.
• Instruments detected a sharp rise in seismic tremors and volcanic gas buildup over the two weeks leading up to the blasts.
• Ballistic ejecta mixed with searing gas clouds and lava traveled up to 8 km from the crater and descended as avalanches up to 5 km down the volcano’s slopes.
• The August 1 events are part of a heightened eruptive phase at Lewotobi Laki-Laki that began in early 2024 and has produced multiple high columns this summer.
• Despite the intensity of the explosions, no casualties, structural damage or flight disruptions have been reported and monitoring remains active.
