Magnitude 6.8 earthquake strikes off Indonesia's Talaud Islands, GFZ says

The quake was at a depth of 77 km (47.85 miles), GFZ said.

The Indonesian geophysics agency BMKG reported 7.1 magnitude reading, at 17 km depth. It also reported a few subsequent quakes.

BMKG said the quakes do not have the potential to trigger tsunami waves.

Some people in Manado on the northern tip of Sulawesi island said the quake was felt strongly there. There were no immediate reports of damage.

Indonesia straddles the so-called Pacific Ring of Fire, an area of high seismic activity where multiple tectonic plates meet and earthquakes are frequent.
