Chilling pictures show the huge damage caused after a huge earthquake struck the east coast of Taiwan.
A tsunami warning has been issued after the US Geological Survey (USGS) initially measured the quake at a dangerous magnitude 7.2 and with a depth of just over 6 miles, before it was downgraded to 6.9.
Shaking was felt in the capital of Taipei, though the epicentre of the quake is reported to have been in Taitung county, which has a population of over 100,000.
The US Tsunami Warning Centre has issued a threat alert, while Japan's Meteorological Agency warned of waves up to 1-mete high could reach their shores.
Yonaguni island in Japan is only around 70 miles east of Taiwan, though Taiwan itself only issues Tsunami warnings if the earthquake is over magnitude 7.0.
The USGS said people reported an intensity of nine on their community determined intensity scale (CDI), which is deemed to have 'violent' shaking and heavy damage.
Initial reports indicate some damage including a possible derailed train carriage and a collapsed two-storey residential building, but it is not clear if there are any casualties.
Unverified video footage from the quake appears to show the Gaoliao Bridge in Yuli Township in a state of complete collapse.
It is the second major earthquake in as many days as a 6.4 magnitude tremor rocked the self-governing island on Saturday and several aftershocks have been felt since.
It was unclear if there were any casualties in the Saturday earthquake as grim footage revealed collapsed buildings and rocked trains.
The strength of the quake is reported to have been unexpected due to the large tremor the day before.
Geoscientist Dr. Steven J. Gibbons said on Twitter that Sunday's earthquake looked "likely very dangerous" and "that it is about a 1 in 20 chance that an earthquake will be followed by a larger aftershock".
Taiwanese TV company TVBS reporter Tingting Lius said before the recent earthquake: "As of 8.55am on Sunday, a total of 47 aftershocks were felt in Taiwan.
"The central weather bureau also didn’t rule out [the] possibility of an aftershock with magnitude more than 5 happening over the next few days."
Serious quakes have been reported in the past and over 100 people died as recently as 2016. A 7.3 magnitude quake killed more than 2,000 people in 1999.
Buildings are usually protected in some way against geological events and the famous Taipei 101 has a huge steel pendulum within the skyscraper to stop it from swaying during a tremor.
