A strong earthquake has struck the Pacific island of Guam. There are no immediate reports of damage and no tsunami alert has been issued.
The 7.1-magnitude quake hit the island at 12.09 pm local time (0209 GMT) on Sunday, with its epicentre at a depth of 30km, Japan's meteorological agency said.
Residents of Guam said high-rise buildings swayed and goods fell off supermarket shelves.
But two hours after the quake, local television reported no damage to buildings on Guam, an island east of the Philippines which is home to a major US military base.
"We felt it. It was swinging back and forth for a minute or two," Patrick Chan, a meteorologist at the US National Weather Service, said.
"It's not expected to cause a tsunami," the Guam-based meteorologist said.
The Pacific Tsunami Warning Centre, based in Hawaii, said in a statement that there was "no destructive widespread tsunami threat".
Neither Guam nor the Philippines have issued tsunami warnings.
