A major earthquake hit off the coast of western Sumatra, Indonesia, on Monday, the U.S. Geological Survey reported.

The preliminary magnitude was put at 7.5 by the USGS.

It said the quake, which hit at around 10:42 a.m. ET (9:42 p.m. local time) was located 150 miles west of Bengkulu, Sumatra, near the Mentawi islands off Sumatra.

The USGS said the epicenter of the temblor was 8.8 miles deep.

A tsunami warning was issued by the Indonesian earthquake monitoring agency, which measured the quake at 7.2.

The Pacific Tsunami Warning Center said historical data suggested any wave it created would not be destructive.
