Earlier shocks
A 6.8-magnitude earthquake struck off the coast of Indonesia’s Talaud Islands on Jan. 10, the GFZ said.
The GFZ said the earthquake occurred at a depth of 77 km (47.85 mi).
Indonesia’s geophysical agency BMKG recorded a slightly higher magnitude of 7.1 at a depth of 17 km and recorded several aftershocks.
The BMKG said the earthquake was not expected to generate tsunami waves.
Residents of Manado, located on the northern tip of Sulawesi island, reported feeling the tremors strongly, but there were no immediate reports of damage.
A magnitude 4.6 earthquake struck North Sumatra on the morning of December 28, the National Center for Seismology (NCS) said.
In a post on X, the agency said: “EQ M: 4.6, Date: 28/12/2025 07:45:56 IST, Latitude: 0.41 N, Long: 99.75 E, Depth: 64 km, Location: North Sumatra, Indonesia.”

In early October, a stronger earthquake measuring 6.6 on the Richter scale hit West Papua, Indonesia, according to the NCS. The earthquake struck at 11:57 am (IST) with an epicenter at 2.26 degrees south latitude and 138.86 degrees east longitude at a depth of 55 kilometers.
Earthquakes, volcanic eruptions and tsunamis frequently affect Indonesia, a nation of more than 270 million people due to its location on the “Ring of Fire”.
The Ring of Fire, or Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
It’s a horseshoe-shaped belt roughly 40,000 km long and about 500 km wide that contains two-thirds of all the world’s volcanoes and 90 percent of Earth’s earthquakes.
