Washington, August 15: An earthquake with a magnitude of 6.6 hit the Mariana Islands region on Sunday, continuing a series of strong aftershocks 24 hours after a 7.2 tremor, US geologists said.
There have been 10 quakes of magnitude 5.0 or stronger since the powerful quake on Saturday morning but all were in a remote area of the Pacific Ocean and well away from populated areas.
The latest quake struck at 9:01am (2301 GMT on Saturday) at a depth of 22.5 kilometres (14 miles) and centred 570 kilometres from the Northern Marianas capital Saipan, the US Geological Survey said.
The Hawaii-based Pacific Tsunami Warning Centre said there was no indication of any widespread tsunami threat.
