Earthquake Indonesia Today: Live Map and Latest Quakes

Key context

What is normal in Indonesia

Over the 30 years 1996-2025, USGS recorded 6,536 earthquakes of M5 or more in Indonesia: about 218 a year, or 18 a month. The past 12 months had 271, about 24% more than the 30-year average. Quakes of M6 or more average 17.4 a year here (521 in 30 years), and 13 of them happened in the past 12 months.

Busy years usually mean one large quake and its aftershocks: the peak year here was 2007 with 419. Counts cover the Indonesian archipelago from Aceh to Papua and its surrounding trenches. They come from the USGS ComCat catalog, which records small quakes more completely in the US than elsewhere, so compare like with like.

Plates and faults

Indonesia sits where the Indo-Australian Plate dives beneath the Sunda Plate along the Sunda Trench, south and west of Sumatra and Java, at 5-7 cm per year. This megathrust produced the M9.1 Sumatra-Andaman quake and the Indian Ocean tsunami of 26 December 2004, and the M8.6 Nias quake three months later.

East of Bali the picture gets complicated: the Australian Plate collides with the Banda Arc, two slabs sink under the Molucca Sea, and strike-slip faults cut through Sulawesi and Papua. Indonesia has quakes at all depths, down to more than 600 km under the Banda and Flores seas.

• Sunda megathrust (west of Sumatra, south of Java)
• Great Sumatran Fault (along Sumatra's mountains)
• Flores back-arc thrust (north of Bali, Lombok and Flores)
• Palu-Koro Fault (Sulawesi, 2018 Palu quake and tsunami)
• Banda Arc and Molucca Sea (many deep quakes)
• New Guinea fold belt and faults (Papua)

Where the recent quakes were

Of the 124 quakes of the past 30 days, 90 were shallow (less than 70 km deep), 31 intermediate (70-300 km) and 3 deep (more than 300 km). 124 reached M4 or more. The places USGS named most often were Ruteng, Indonesia (17), Tambolaka, Indonesia (12), Tobelo, Indonesia (8).

Official sources and warnings

• BMKG (Meteorology, Climatology and Geophysics Agency): Indonesia's official source for quake reports and tsunami warnings (InaTEWS); its InfoBMKG app sends alerts.
• BNPB (National Disaster Management Agency): national disaster response.

What to do in an earthquake

If you feel shaking: Drop, Cover and Hold On until it stops. Stay away from windows and heavy furniture, and do not run outside during the shaking. On a coast, strong or long shaking is a natural tsunami warning: move to high ground or inland at once, on foot if you can. Then follow your local officials; this page is not a warning service.

In Indonesia, follow BMKG warnings. On any coast, if shaking is strong or long, or the sea pulls back, move to high ground immediately without waiting for an official warning.
