Ukuran:

BMKG menyatakan peluang tsunami akibat erupsi Gunung Anak Krakatau berada di bawah 40 persen, berdasarkan pemantauan sensor tsunami gauge dan High-Frequency Radar Array yang tidak menunjukkan anomali muka air laut signifikan, meskipun tercatat gangguan geomagnetik dan petir vulkanik dengan intensitas lebih rendah dari letusan awal. Abu vulkanik dari erupsi telah menyebar hingga ke Jakarta, Jawa Barat, Banten, Lampung, dan Bengkulu pada ketinggian hingga 50.000 kaki. BMKG mengoptimalkan pemantauan terpadu selama 24 jam dan mengimbaup masyarakat pesisir Selat Sunda untuk meningkatkan kewaspadaan namun tetap tenang.

Poin-Poin Utama

BMKG stated the potential tsunami from Anak Krakatau eruption is low at 40%.
20 tsunami gauge sensors around the Sunda Strait showed no water level anomalies.
High-Frequency Radar Array at Carita and Tanjung Lesung recorded tsunami probability under 40%.
Sea wave height near Anak Krakatau remained around 1 meter.
BMKG recorded geomagnetic disturbances and volcanic lightning as secondary phenomena.
Sensors in South Lampung and Serang detected geomagnetic disturbances correlating with increased volcanic lightning.
The intensity of these secondary disturbances was smaller than the initial eruption.
BMKG conducts 24/7 integrated multi-instrument monitoring for national preparedness.
BMKG collaborates with PVMBG-Badan Geologi for precise, fast, and accurate data analysis.
BMKG advised coastal residents along the Sunda Strait to stay alert but calm.
Volcanic ash from the eruption reached Jakarta and West Java on September 6, 2026 at 07:00 WIB.
At altitudes up to 20,000 ft, volcanic ash spread eastward-southward covering parts of Jakarta, Banten, and West Java.
At altitudes up to 50,000 ft, volcanic ash spread southwestward-northwestward covering Banten, Lampung, and Bengkulu.
The second ash cluster also reached the southern Sunda Strait and the Indian Ocean west of Bengkulu, Lampung, and Banten.
Weather forecast for Anak Krakatau from September 6-8, 2026 is clear to cloudy with east-southeast winds at 31-37 km/h.
