Indonesia Volcano Mount Anak Krakatau Records 11 Eruptions on Monday
Indonesia volcano Mount Anak Krakatau recorded a total of 11 eruptions on Monday, August 24, 2026, with ash columns reaching as high as 400 meters above the summit while the alert status remained at Level III (Siaga). [2] [3]
Overview of Monday's Eruptive Activity
The Indonesia volcano Mount Anak Krakatau in the Sunda Strait, Lampung Selatan, produced 11 eruptions from morning through late afternoon on August 24, 2026. [2] Six successive eruptions took place between 9:41 a.m. and 11:22 a.m. WIB, followed by four more in the afternoon. [3] [4] The activity included ash columns that varied in height and direction, with seismic instruments capturing amplitudes between 49 and 67 millimeters and event durations ranging from 20 seconds to more than one minute. [2] [3] Officials noted that the eruptions remained ongoing at the time some reports were prepared, and the pattern showed repeated volcanic activity without signs of immediate decline. [2]

Six consecutive eruptions occurred at the Indonesia volcano between 9:41 a.m. and 11:22 a.m. WIB, each producing ash columns between 200 and 250 meters above the summit that drifted west and northwest. [3] [4] The first eruption at 9:41 a.m. WIB sent ash 250 meters high with a maximum amplitude of 52 millimeters lasting 1 minute and 17 seconds. [4] The second at 9:43 a.m. WIB also reached 250 meters with an amplitude of 49 millimeters over 25 seconds. [3] The third eruption at 10:11 a.m. WIB produced a 200-meter column with 53 millimeters amplitude. [4] The fourth at 10:24 a.m. WIB reached 250 meters, and the fifth at 10:48 a.m. WIB likewise reached 250 meters. [3] The sixth eruption at 11:22 a.m. WIB generated a 200-meter column, equivalent to 357 meters above sea level, with a maximum amplitude of 51 millimeters lasting 20 seconds. [4] All morning events featured gray to black ash with medium to thick intensity. [3]
Afternoon Eruptions
Four additional eruptions took place during the afternoon hours on August 24, 2026, bringing the daily total to 11 at the Indonesia volcano. [2] The first afternoon event occurred at 3:24 p.m. WIB with ash columns reaching 400 meters above the summit or 557 meters above sea level, showing gray to black ash of medium to thick intensity moving north and northeast at an amplitude of 67 millimeters for 26 seconds. [2] A subsequent eruption at 4:43 p.m. WIB produced ash approximately 300 meters above the summit drifting north and northeast. [2] Three minutes later at 4:46 p.m. WIB another eruption sent ash 300 meters high in the same directions. [2] The final recorded event at 5:09 p.m. WIB also reached 400 meters above the summit. [2] These afternoon events contributed to the repeated eruptive pattern observed throughout the day. [2]
Current Alert Status and Safety Measures
Authorities have maintained the Level III (Siaga) alert status for the Indonesia volcano Mount Anak Krakatau. [3] [4] Residents, visitors, tourists, and hikers are prohibited from approaching the volcano or conducting any activities within a three-kilometer radius of the active crater. [3] The Geological Agency emphasized that this exclusion zone remains in effect due to the ongoing eruptive sequence. [4] No changes to the alert level were reported despite the multiple events recorded on August 24, 2026. [3]

Monitoring Efforts
Personnel at the Mount Anak Krakatau monitoring post in Desa Hargo Pancuran, Kecamatan Rajabasa, Lampung Selatan, stated that volcanic activity continues to be observed closely following the repeated eruptions. [2] Andi Suwardi of the monitoring post noted that eruptions had occurred repeatedly since morning, with the count reaching 11 by 5:09 p.m. WIB. [2] Plt. Head of the Geological Agency Lana Saria reported that the eruptive sequence was still in progress when statements were issued and confirmed the continued placement at Level III (Siaga). [3] [4] Monitoring instruments recorded all seismic details, and officials indicated that observations would persist amid the sustained activity. [2]
Seismic Recordings Across Events
Seismic data from the full day of eruptions at the Indonesia volcano showed amplitudes ranging from 49 to 67 millimeters, with individual durations spanning 20 seconds to over one minute. [2] [3] Morning events included amplitudes of 52, 49, 53, and 51 millimeters, while afternoon recordings reached a peak of 67 millimeters. [4] [2] These measurements accompanied ash columns of varying heights and confirmed the medium to thick intensity of emissions drifting in multiple directions. [3] The consistent seismic signatures supported ongoing surveillance by the Geological Agency without alteration to established safety protocols. [4]
What to watch next: Officials will continue monitoring the repeated activity at Mount Anak Krakatau while the Level III (Siaga) status and three-kilometer exclusion zone remain in place.
