A powerful earthquake struck southeastern Taiwan on Sunday, knocking down at least one building in a small town.

The quake struck at 2:44 p.m. (0644 GMT) about 50 kilometers (30 miles) north of the city of Taitung at a depth of 10 kilometers, the United States Geological Survey said.

Its initial magnitude was reported as a magnitude 7.2, but USGS later downgraded it to a magnitude 6.9 quake. The Taiwan Meteorological Bureau recorded a magnitude of 6.8.

Japan’s Meteorological Agency and the Pacific Tsunami Warning Center issued tsunami warnings shortly after the quake, but both later sent updated bulletins saying high waves were no longer a threat.

Live TV footage from the affected Japanese islands did not immediately show signs of high waves.

In Taiwan, at least one building with a supermarket on the ground floor collapsed in the city of Yuli, according to the island’s semi-official Central News Agency.

Video footage posted by CNA showed panicked residents running toward the building, which had collapsed, kicking up a thick cloud of dust.

The Taiwan Railway Administration (TRA) said a train derailed at Dongli train station in Hualien after being hit by concrete from a canopy that had come loose during the quake.

Photos shared on social media showed the train’s six carriages parked at an angle in the station.

TRA said the 20 passengers on board had been evacuated and no injuries had been reported.

Tremors were also felt in the capital, Taipei, as residents posted videos of chandeliers and paintings on social media.

A magnitude 6.6 quake struck the same region on Saturday, and since then there have been multiple tremors with minimal damage in a mountainous, sparsely populated rural region.

But Sunday’s quake was much stronger.

The China Earthquake Network Center said tremors were felt in coastal areas such as Fujian, Guangdong, Jiangsu and Shanghai.

Taiwan is regularly hit by earthquakes due to the island’s proximity to the intersection of two tectonic plates.

The mountainous island lies on the “Ring of Fire,” an arc of intense seismic activity that stretches through Southeast Asia and across the Pacific Basin.

Most of Taiwan’s population lives on the flat west coast and in the capital, Taipei.

The scenic east coast is more remote and less populated, but a major tourist magnet.

Earthquakes hit it regularly, and most cause minimal damage, but the island also has a long history of deadly concussions.

Hualien, a tourist hotspot, was hit by a 6.4 magnitude earthquake in 2018, killing 17 and injuring nearly 300.

In September 1999, a 7.6 magnitude tremor killed around 2,400 people in the deadliest natural disaster in the island’s history.
