An earthquake of magnitude 6.7 hit near the China-Russia border today, but there were no immediate reports of casualties or damage.
The quake, which occurred at 1.13am (Irish time), was centred midway between the Russian city of Vladivostok and Chongjin, North Korea's third largest city.
It struck at a depth of 563km, the US Geological Survey said.
The Pacific Tsunami Warning Centre put the coordinates at 42.7 north and 130.9 east.
Early estimates put the magnitude at 6.9.
The USGS later put the figure at 6.7, a powerful quake but one with effects on the surface likely to be minimised by the extreme depth.
