Rare earthquake felt in Hong Kong

HONG KONG—A rare earthquake rattled Hong Kong early Thursday, prompting concerned local residents to call the authorities, the Hong Kong Observatory said.

There were no reports of damage from the quake, which had a magnitude of 4.2, the US Geological Survey said, adding that it struck at a relatively shallow depth of 19 kilometers (11.5 miles) at 02:34 (1834 GMT).

It hit the Chinese province of Guangdong, some 119 kilometers northeast of Dongguan – a factory hub – which is around 100 kilometers from Hong Kong.

The Hong Kong Observatory measured the quake at 4.5 magnitude and said it was felt by residents in the glitzy financial hub.
