Ukuran:

BMKG telah memasang lebih dari 20 tsunami gauge, 20 lebih sensor seismograf, dan high frequency radar di sekitar Selat Sunda untuk memantau aktivitas Gunung Anak Krakatau, namun hingga kini belum ditemukan anomali kenaikan muka air laut maupun indikasi tsunami. Hasil pemantauan melalui tiga rekaman magnet bumi di Lampung Selatan, Serang, dan Sukabumi menunjukkan kecenderungan penurunan aktivitas erupsi dibandingkan erupsi pada 4 dan 5 September 2026. Informasi tersebut disampaikan Kepala BMKG Teuku Faisal Fathani dalam rapat terbatas yang dipimpin Presiden Prabowo Subianto pada Senin (7/9/2026).

Poin-Poin Utama

BMKG installed over 20 tsunami gauges around the Sunda Strait to monitor Mount Anak Krakatau activity.
No sea level rise anomaly or tsunami indication detected from Mount Anak Krakatau eruption as of monitoring.
BMKG Head Teuku Faisal Fathani delivered the update during a limited cabinet meeting on September 7, 2026.
President Prabowo Subianto led the virtual meeting from Merdeka Palace, Jakarta, covering NTT earthquake, Anak Krakatau eruption, and forest fires.
BMKG monitors Mount Anak Krakatau eruption through three geomagnetic recorders in South Lampung, Serang, and Sukabumi.
Eruption activity showed declining trend compared to September 4 and 5, 2026 events.
Geomagnetic disturbance amplitude and volcanic lightning strikes decreased relative to the September 4 night and September 5 eruptions.
BMKG data on magnetic fields and volcanic lightning indicates a decay process in eruption activity.
Over 20 seismograph sensors installed around Sunda Strait to monitor eruption and potential flank collapse.
Sensor network prepared for possible tsunami similar to the 2018 event.
BMKG deployed high frequency radar to monitor wind wave conditions along Carita to Tanjung Lesung coast.
Radar configured into tsunami mode to detect incoming tsunamis within approximately 150 km range.
2018 Sunda Strait tsunami referenced as benchmark for current preparedness measures.
