Tengger Caldera volcano (Eastern Java) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 February-14 February 2023 (New Activity / Unrest)

PVMBG sent a team of scientists to investigate Tengger Caldera's Bromo cone after an increase in activity was detected on 3 February, characterized by crater incandescence, rumbling sounds, and a strong sulfur dioxide odor. They observed somewhat dense white emissions rising as high as 300 m during 9-12 February and heard moderate-to-strong rumbling noises. A sulfur dioxide odor was strong near the crater and measurements indicated that levels were above the healthy (non-hazardous) threshold of 5 parts per million; differential optical absorption spectroscopy (DOAS) measurements indicated an average flux of 190 tons per day on 11 February.

Tengger Caldera volcano (Eastern Java) - Smithsonian / USGS Weekly Volcanic Activity Report for 1 February-7 February 2023 (New Activity / Unrest)

PVMBG reported that activity at Tengger Caldera's Bromo cone increased at 2114 on 3 February and was characterized by crater incandescence, rumbling sounds, and a strong sulfur dioxide odor. The report noted that sometimes-dense white plumes rose as high as 900 m above the summit during the previous week and through 7 February, and that vegetation on the E caldera wall was yellow and withered. The seismic network recorded continuous tremor and deep and shallow volcanic earthquakes. Read all
