A cluster of earthquakes struck the island republic of Taiwan early Tuesday, the strongest having a magnitude of 6.1, according to the U.S. Geological Survey.

There were no reports of casualties in the quakes, although there were further damages to two multi-story buildings that had been evacuated following a magnitude 7.4 quake that hit the island earlier this month, killing 13 people and injuring over 1,000. That earthquake was centered along the coast of the rural and mountainous Hualien County.

It was the strongest earthquake in the past 25 years in Taiwan and was followed by hundreds of aftershocks

According to the USGS, Tuesday’s quake of 6.1 magnitude had its epicenter 28 kilometers (17.5 miles) south of the city of Hualien, at a dept of 10.7 kilometers. The half-dozen other quakes ranged from magnitude 4.5 to magnitude 6, all near Hualien. Taiwan’s own earthquake monitoring center put the magnitudes of the initial quake at 6.3. Such small discrepancies are common between monitoring stations.

Rescuers searched for dozens of people out of contact on April 4, a day after Taiwan’s strongest earthquake in a quarter century damaged buildings, caused multiple rockslides and killed nine people.

In the eastern coastal city of Hualien near the epicentre, workers used an excavator to put construction materials around the base of a damaged building to stabilise it and prevent a collapse. Mayor Hsu Chen-wei previously said 48 residential buildings were damaged. Some of the damaged buildings tilted at precarious angles with their ground floors crushed.

More than 1,000 people were injured in the quake that struck on Wednesday morning. Of the nine dead, at least four were struck inside Taroko National Park, a tourist attraction famous for its scenes of canyons and cliffs in Hualien County, about 150 km (90 miles) from the island’s capital Taipei.

“Nearly 150 people were either still trapped or out of contact on April 4,” the National Fire Agency said.

About two dozen tourists and some others were stranded in the park. The Health and Welfare Ministry said 64 others were workers at a rock quarry. Six workers from another quarry were airlifted from the area where access was cut off because roads were damaged by falling rocks.

Several people, including six university students, were also reported to be trapped. Around 50 people, mostly employees at the hotel earlier reported to be in the national park, were out of contact with authorities.

For hours after the quake, TV showed neighbours and rescue workers lifting residents through windows and onto the street from damaged buildings where the shaking had fused shut the doors. It wasn’t clear on Thursday morning if any people were trapped in the damaged buildings.

The temblor and aftershocks caused many landslides and damaged roads, bridges and tunnels. The national legislature and sections of Taipei’s main airport had minor damage.

Taiwan measured the initial quake’s strength as 7.2 magnitude while the U.S. Geological Survey put it at 7.4. The Central Weather Administration has recorded more than 300 aftershocks from Wednesday morning into Thursday.

Taiwan is regularly jolted by earthquakes and its population is among the best prepared for them. It also had stringent construction requirements to ensure buildings are quake-resistant.

The economic losses caused by the quake are still unclear. The self-ruled island is the leading manufacturer of the world’s most sophisticated computer chips and other high-technology items that are sensitive to seismic events.

Hualien was last struck by a deadly quake in 2018 that killed 17 people and brought down a historic hotel. Taiwan’s worst recent quake on September 21, 1999, a magnitude of 7.7 temblor, caused 2,400 deaths, injuring around 1,00,000 and destroying thousands of buildings.
