A strong 6.9 magnitude quake struck southeast of Taiwan Monday, the US Geological Survey said, but no tsunami warning was immediately issued.
The quake, which could be felt as far away as Taiwan’s capital Taipei, hit at 10:59 am (0259 GMT) at a depth of 10 kilometres (six miles) with an epicentre 269 kilometres off the eastern city of Taitung, the USGS said.
There were no immediate reports of casualties or damage, according to the interior ministry’s fire agency.
“The quake hit pretty far out at sea, but we’ll keep monitoring,” an official with the agency told AFP.
Taiwan’s Central Weather Bureau, which uses a different measure from the USGS, gave the magnitude of the quake as 6.6.
