An earthquake with a preliminary magnitude of 7.3 struck 93 miles north-northwest off the coast of Kota Ternate, Indonesia, on Saturday, the U.S. Geological Survey reported.

The quake was later downgraded to a magnitude-7.1.

The quake struck at 10:31 a.m. local time at a depth of 29.2 miles, according to the USGS.

No Pacific-wide destructive tsunami is expected, but “hazardous tsunami waves are possible for coasts located within 186 miles of the earthquake epicenter,” according to the National Weather Service Pacific Tsunami Warning Center.

The estimated time of arrival for the initial tsunami wave along Indonesia’s coast is within the next six hours, the warning center said.

The Pacific Tsunami Warning Center said it will update its warning within the hour.
