An earthquake measuring 6.9 magnitude on the Richter scale jolted the Big Island of Hawaii on Friday, the US Geological Survey (USGS) said. The quake struck 16 km southwest of Leilani Estates, Hawaii at 12:32 p.m. local time. The epicenter, with a depth of 5 km, was initially determined to be at 19.3702 degrees north latitude and 155.0321 degrees west longitude, Xinhua reported. "This is in almost exactly the same location as the deadly 1975 M 7.1 earthquake," the USGS tweeted.

The Pacific Tsunami Warning Center said there is no tsunami threat to Hawaii following the 6.9-magnitude earthquake.
