An earthquake with a preliminary magnitude of 6.8 struck Thursday morning in the region where China, Russia and North Korea meet, the U.S. Geological Survey reported.

The temblor hit about 9:15 a.m., and office towers in Beijing swayed slightly for about a minute.

The USGS said the quake was centred on the Russian coast along the sea of Japan, 61 miles (98 km) west-southwest of Vladivostok, Russia and about 70 miles (110 km) east from Yanji city in northeast China’s Jilin province.

A man at the Jilin province earthquake bureau said the agency was trying to get more information and did not have any immediate details.
