The Geological Agency of the Ministry of Energy and Mineral Resources\n(ESDM) has lowered the status of Mount Sinabung in Karo Regency, North\nSumatra, from Level III (Alert) to Level II (Watchful), effective from\n09:00 WIB on 17 October 2026.<\/p>\n
\u201cIt is true that Mount Sinabung\u2019s activity level has been lowered\nfrom Level III (Alert) to Level II (Watchful),\u201d said Armen Putra, head\nof the Mount Sinabung monitoring post at the Geological Agency of the\nMinistry of Energy and Mineral Resources, on Saturday (17 October).<\/p>\n
Mount Sinabung was visually clear at times and at other times\nobscured by cloud. White smoke was observed rising from the main crater,\nvarying from thin to moderately thick, and reaching heights of around\n50\u2013600 metres above the summit.<\/p>\n
Instrumental monitoring recorded the following seismic activity\nbetween 8 and 15 October 2026: four gas-release earthquakes, two\nlow-frequency earthquakes, five hybrid or multiphase earthquakes, seven\ndeep volcanic earthquakes, one local tectonic earthquake, 39 distant\ntectonic earthquakes and one flood-vibration event.<\/p>\n
Electronic Distance Measurement (EDM) deformation data showed a\nfluctuating pattern, with deflation towards the end of the period.\nDeformation data from the tiltmeter at Laukawar Station also indicated\ndeflation along the measured axis.<\/p>\n
Visually observed gas emissions at the summit have fallen\nsignificantly, with the emissions becoming less intense and the smoke\nturning lighter in colour.<\/p>\n
There has also been a decline in the number of deep volcanic\nearthquakes and tectonic earthquakes originating around Mount Sinabung,\nreducing the potential for an eruption.<\/p>\n
Based on a comprehensive analysis and evaluation conducted by the\nGeological Agency through 15 October 2026, Mount Sinabung\u2019s activity\nlevel was lowered from Level III (Alert) to Level II (Watchful),\neffective from 09:00 WIB on 17 October 2026.<\/p>\n
Nevertheless, residents, visitors and tourists are advised not to\ncarry out activities within a 3-kilometre radius of the summit, or\nwithin a 4-kilometre sectoral radius in the south-eastern sector of\nMount Sinabung.<\/p>\n
The Geological Agency also emphasised that villages whose residents\nhave been relocated should not be used again as permanent settlements.\nDaily activities may continue outside the recommended exclusion\nzones.<\/p>\n
\u201cResidents, visitors and tourists should comply with the new\nrecommendations if Mount Sinabung\u2019s activity increases and\/or its alert\nlevel rises,\u201d Armen said.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/mount-sinabungs-alert-status-downgraded-to-watchful-1792255819", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
