(CNN) -- An earthquake with a magnitude of 6.3 shook Indonesia Tuesday at 8:08 p.m. (8:08 a.m. ET), according to the U.S. Geological Survey.
The epicenter of the temblor was 26.6 miles deep in the Molucca Sea, within 100 miles of the Moluccas Islands and Sulawesi, in the eastern part of the Indonesian archipelago.
The quake did not pose an immediate tsunami threat to Pacific coastlines, the U.S. Geological Survey said. But the U.S.G.S. warned that "earthquakes of this size sometimes generate local tsunamis" that could affect areas within a few hundred kilometers of the epicenter.
