Kabul: A 6.9 magnitude earthquake hit the sparsely populated southeastern part of Taiwan on Sunday, the island’s weather bureau said, derailing train carriages, causing a convenience store to collapse and trapping hundreds on mountain roads.
The weather bureau said the epicentre was in Taitung County, and followed a 6.4 magnitude temblor on Saturday evening in the same area, which caused no casualties.
The U.S. Geological Survey measured Sunday’s quake at a magnitude 7.2 and at a depth of 10 km (six miles).
Taiwan’s fire department said all four people were rescued from a building housing a convenience store that collapsed in Yuli, while three people whose vehicle fell off a damaged bridge were rescued and taken to hospital.
The Taiwan Railways Administration said six carriages came off the rails at Dongli station in eastern Taiwan after part of the platform canopy collapsed, but the fire department said there were no injuries.
The U.S. Pacific Tsunami Warning Center issued a warning for Taiwan after the tremor but later lifted the alert. Japan’s weather agency lifted a tsunami warning for part of Okinawa prefecture.
Taiwan lies near the junction of two tectonic plates and is prone to earthquakes.
More than 100 people were killed in a quake in southern Taiwan in 2016, while a 7.3 magnitude quake killed more than 2,000 people in 1999.
