New Delhi, Aug 12: An earthquake of magnitude 6.4 on Richter scale struck remote part of Alaska on Sunday, the US Geographical Survey confirmed. The tremors were felt at 6:58 am on Sunday. No reports of injuries or any damage to property were reported.

The agency said that the earthquake had a depth of about 6 miles (9.9 kilometers.) State seismologist Mike West told the Anchorage Daily News that the quake was the biggest recorded in the North Slope by a substantial amount. “This is a very significant event that will take us some time to understand,” he told the Daily News.

The previous most powerful quake in the North Slope was in 1995 at magnitude 5.2, West told the newspaper. The newspaper says that Alyeska Pipeline said the earthquake did not damage the trans-Alaska pipeline.

At 7:14 a.m., a magnitude 5.1 earthquake hit another area in northern Alaska. The USGS says the earthquake hit a spot about 340 miles (549 kilometres) northeast of Fairbanks.

According to USGS data and the earthquake centre, several strong aftershocks were also felt following the quake.
