Lokasi Pelaporan: Jakarta (Area terbuka DKI Jakarta)

Banten|Jakarta, 16 September 2026- ISI BERITA UTAMA
Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) kembali mengeluarkan peringatan tegas dan imbauan waspada terkait potensi gempa bumi skala besar (Megathrust) yang bersumber di zona Selat Sunda tanggal (12\/9\/26).

Berdasarkan kajian BMKG dan Badan Riset dan Inovasi Nasional (BRIN), potensi gempa di segmen ini diperkirakan dapat mencapai magnitudo hingga 8,9.

Detail Estimasi Dampak Bencana:
Potensi Tsunami & Waktu Tempuh Gelombang:

Pesisir Jakarta: Gelombang tsunami akibat Megathrust Selat Sunda diperkirakan membutuhkan waktu sekitar 2,5 jam untuk menjalar hingga ke Pesisir Utara Jakarta, dengan estimasi ketinggian tsunami mencapai sekitar 0,5 meter.

Pesisir Banten & Jawa Barat: Berbeda dengan Jakarta, wilayah pesisir Banten dan Jawa Barat yang letaknya sangat dekat dengan pusat gempa berpotensi terdampak gelombang tsunami jauh lebih tinggi, yaitu melebihi 1,5 meter.

Guncangan dan Ancaman Kerusakan Bangunan di Jakarta:
Ancaman utama bagi ibu kota bukan hanya tsunami, melainkan guncangan gempa dahsyat dengan skala intensitas dirasakan mencapai 6 hingga 7 MMI (Modified Mercalli Intensity).

Karakteristik tanah DKI Jakarta yang mayoritas berupa lapisan aluvial lunak dapat memperkuat getaran gempa (amplifikasi), sehingga berisiko tinggi merusak struktur bangunan gedung tingginya maupun infrastruktur pemukiman.

Ancaman Tambahan (Sesar Aktif Darat):
Selain zona Megathrust Selat Sunda, wilayah Jakarta dan sekitarnya juga dibayangi bahaya guncangan dari jalur sesar aktif darat, salah satunya Sesar Cimandiri. Meskipun berskala menengah, guncangan dari sesar ini tetap mampu merobohkan konstruksi yang tidak bersertifikasi tahan gempa.

PANDUAN MITIGASI DAN KESIAPSIAGAAN (BMKG & BPBD)
Hingga saat ini belum ada teknologi yang mampu memprediksi waktu pasti terjadinya gempa bumi. Oleh karena itu, kesiapsiagaan mandiri dan respon cepat adalah hal mutlak yang wajib dipahami:

Penghuni Gedung Tinggi \/ Perkantoran:
Tetap tenang, hindari panik berlebihan.

Segera berlindung di bawah meja yang kokoh dan prioritaskan perlindungan pada area kepala.

Dilarang menggunakan lift. Gunakan tangga darurat secara tertib saat kondisi telah stabil.

Masyarakat Kawasan Pesisir:
Terus memantau Early Warning System (EWS) dari BMKG.
Apabila merasakan guncangan gempa kuat lebih dari 7,0 SR atau berdurasi panjang, segera lakukan evakuasi mandiri ke tempat yang lebih tinggi tanpa menunggu sirine tsunami.

Pemerintah & Pengembang (Developer):
Wajib menguji dan memperketat evaluasi ketahanan struktur gedung serta infrastruktur publik terhadap risiko guncangan gempa tinggi (standar earthquake-resistant building).
