A strong and shallow earthquake registered by the USGS as M6.7 hit 43 km ESE of Palu, Indonesia, at 03:27 UTC on June 16, 2026. The agency is reporting a depth of 10 km (6.2 miles). EMSC is reporting the same magnitude and depth.

The epicenter was located 43 km (27 miles) ESE of Palu (population 373 218), 69 km (43 miles) WNW of Poso (population 47 477), 161 km (100 miles) N of Masamba (population 38 024), 209 km (130 miles) N of Palopo (population 184 681), and 209 km (130 miles) N of Rantepao (population 40 438), Indonesia.

16 000 people are estimated to have felt severe shaking, 165 000 very strong, 574 000 strong, 676 000 moderate, and 3.2 million light.

The USGS issued a Yellow alert for shaking-related fatalities and economic losses. Some casualties and damage are possible, and the impact should be relatively localized.
