Magnitude 5.7 earthquake — Ternate, Indonesia

A magnitude 5.7 earthquake struck the Molucca Sea, north-west of Ternate in Indonesia’s North Maluku region, at 20:16 UTC on 4 August 2026 (05:16 local time on 5 August). The USGS event record places the quake about 127 km north-west of Ternate, at a depth of 35 km, with an epicentre near 1.5066°N, 126.4856°E. European-Mediterranean Seismological Centre data independently recorded a magnitude of 5.7, while giving a slightly different depth estimate of 44 km, reflecting normal differences between seismic agencies’ solutions.

Rapid impact information indicated limited expected effects. The Global Disaster Alert and Coordination System assigned a green alert and assessed the likely humanitarian impact as low; it estimated around 4,000 people were exposed to light, Modified Mercalli intensity IV shaking. The available event information did not indicate severe shaking or a major anticipated impact, although such early assessments are estimates and can be revised as additional observations are reviewed.
