At least four people were feared dead and nearly 60 were injured on Wednesday by a powerful earthquake in Taiwan that damaged dozens of buildings and prompted tsunami warnings that extended to Japan and the Philippines before being lifted.
Officials said the quake and series of strong aftershocks were the strongest to shake the island in decades and warned of more tremors in the days ahead.
“The earthquake is close to land and it’s shallow. It’s felt all over Taiwan and offshore islands,” said the director of Taipei’s Central Weather Administration’s Seismology Centre, Wu Chien-fu.
Strict building regulations and disaster awareness appear to have prevented a major catastrophe for the island, which is regularly hit by earthquakes as it lies near the junction of two tectonic plates.
Wu said the quake was the strongest since one of 7.6-magnitude struck in September 1999, killing around 2,400 people in the deadliest natural disaster in the island’s history.
Wednesday’s magnitude-7.4 quake struck just before 8:00 a.m. local time (0000 GMT), with the United States Geological Survey putting the epicentre 18 kilometres (11 miles) south of Taiwan’s Hualien City, at a depth of 34.8 kilometres.
“I wanted to run out, but I wasn’t dressed. That was so strong,” said Kelvin Hwang, a guest at a hotel in the capital, Taipei, who sought shelter in the lift lobby on the ninth floor.
Social media was flooded with shared videos and images from around the country of buildings swaying as the quake struck.
Dramatic images were shown on local TV of multi-storey structures in Hualien and elsewhere leaning over after it ended.
Roads to Hualien, a mountain-ringed coastal city of around 100,000 people were reported blocked by landslides.
The Central Emergency Operations Center said one person on a hiking trail was suspected to have been crushed to death by a dislodged boulder, adding nearly 60 people had been treated for quake-related injuries.
In Taiwan, Japan and the Philippines, authorities initially issued a tsunami warning but by around 10 am (0200 GMT), the Pacific Tsunami Warning Center said the threat had “largely passed”.
In the capital, the metro briefly stopped running but resumed within an hour, while residents received warnings from their local borough chiefs to check for any gas leaks.
Taiwan is regularly hit by earthquakes as the island lies near the junction of two tectonic plates, while nearby Japan experiences around 1,500 jolts every year.
Across the Taiwan Strait, social media users in China’s eastern province of Fujian, which borders the southern province of Guangdong, and elsewhere said they also felt strong tremors.
China, which sees self-ruled Taiwan as a renegade province, was “paying close attention” to the quake and “willing to provide disaster relief assistance,” state news agency Xinhua said.
The vast majority of quakes around the area are mild, although the damage they cause varies according to the depth of the epicentre below the Earth’s surface and its location.
The severity of tsunamis — vast and potentially destructive series of waves that can move at hundreds of kilometres per hour — also depends on multiple factors.
Japan's largest earthquake ever recorded was a huge 9.0-magnitude underwater shock in March 2011 off the northeast coast of Japan, which caused a tsunami resulting in approximately 18,500 deaths or disappearances.
The 2011 disaster also caused three reactors at the Fukushima nuclear plant to melt down, leading to Japan's worst post-war disaster and the most severe nuclear accident since Chernobyl.
On New Year's Day this year, Japan experienced a significant earthquake when a 7.5-magnitude tremor struck the Noto Peninsula, leading to the deaths of over 230 people, many of whom were in older buildings that collapsed.
