Taipei. Taiwan’s strongest earthquake in a quarter century rocked the island during the morning rush Wednesday, damaging buildings and creating a tsunami that washed ashore on southern Japanese islands. There were no immediate reports of deaths or injuries, and the tsunami threat largely passed about two hours later.

A five-story building in the lightly populated southeastern coastal city of Hualien near the epicenter appeared heavily damaged, collapsing its first floor and leaving the rest leaning at a 45-degree angle. In the capital, tiles fell from older buildings and within some newer office complexes, while debris fell from some building sites. Schools evacuated their students to sports fields, equipping them with yellow safety helmets. Some also covered themselves with textbooks to guard against falling objects as aftershocks continued.

Train service was suspended across the island of 23 million people, as was subway service in Taipei, where a newly constructed above-ground line partially separated. The national legislature, a converted school built before World War II, also had damage to walls and ceilings.

Traffic along the east coast was at a virtual standstill, with landslides and falling debris hitting tunnels and highways in the mountainous region. Those caused damage to vehicles, though it wasn’t clear if anyone was hurt.

Despite the quake striking at the height of the morning rush hour just before 8 a.m. local time, the initial panic faded quickly on the island that is regularly rocked by temblors and prepares for them with drills at schools and notices issued via public media and mobile phone.

Still, the earthquake was strong enough to scare people who are used to such shaking.

“Earthquakes are a common occurrence, and I’ve grown accustomed to them. But today was the first time I was scared to tears by an earthquake,” Taipei resident Hsien-hsuen Keng said. ”I was awakened by the earthquake. I had never felt such intense shaking before.”

She said her fifth-floor apartment shook so hard that “apart from earthquake drills in elementary school, this was the first time I had experienced such a situation.”

There was still no word on casualties from the epicenter near the city of Hualien, where a deadly quake in 2018 collapsed a historic hotel and other buildings. Taiwan’s worst quake in recent years struck on Sept. 21, 1999, with a magnitude of 7.7, causing 2,400 deaths, injuring around 100,000, and destroying thousands of buildings.

The Japan Meteorological Agency said a tsunami wave of 30 centimeters (about 1 feet) was detected on the coast of Yonaguni island about 15 minutes after the quake struck. Smaller waves were measured in Ishigaki and Miyako islands. Japan sent military aircraft to gather information about the impact around the Okinawa region.

Meanwhile, Based on tsunami modeling and analysis by the Meteorology, Climatology, and Geophysics Agency (BMKG), the earthquake in Taiwan does not have a tsunami potential in Indonesia.

"Therefore, the public is advised to remain calm and not believe in false information (hoaxes) or information whose accuracy cannot be verified," the Head of the Earthquake and Tsunami Center of BMKG, Daryono, said.

Taiwan’s earthquake monitoring agency gave the magnitude as 7.2 while the U.S. Geological Survey put it at 7.4. It struck about 18 kilometers south-southwest of Hualien and was about 35 kilometers (21 miles) deep. Multiple aftershocks followed, and the USGS said one of the subsequent quakes was 6.5 magnitude and 11.8 kilometers (7 miles) deep. Shallower quakes tend to cause more surface damage.

The earthquake was felt in Shanghai and several provinces along China’s southeastern coast, according to Chinese media. China and Taiwan are about 160 kilometers (100 miles) apart. China issued no tsunami warnings for the Chinese mainland.

Taiwan lies along the Pacific ”Ring of Fire,” the line of seismic faults encircling the Pacific Ocean where most of the world’s earthquakes occur.
