(CNN) — At least two people are dead and 198 injured in the 6.4 earthquake that struck off the east coast of Taiwan just before midnight Tuesday, said Jeff Lin with the Hualien Police Department.

The quake was centered in the East China Sea about 21 kilometers north-northeast of Hualien City. Light shaking was felt in the capital of Taipei, about 120 kilometers north of Hualien City, according to reports sent to the USGS.

Three buildings have collapsed, including the Marshal Hotel in Hualien City. Lin described the other two collapsed buildings as “city department buildings.”

The injured are mainly from the Marshal Hotel, and a few of the injured are from the department buildings. Officials had no numbers for missing people. In addition, two bridges in the area were damaged and have been closed, Lin said.

A 5.1 aftershock also hit Hualien City shortly after the larger earthquake, according to USGS. There have been several other strong quakes in the area in the last few days.

Cellphone video from Hualien City shows a large building leaning at a dangerous angle as sirens are heard in the background. The video shows people gathering near the building and shining flashlights on windows.

Taiwanese President Tsai Ing-wen said in a tweet that armed forces and government agencies are responding.

“Relief measures are underway,” Tsai tweeted. “Stay safe.”

Flights to the Hualien area have been canceled, Hsu Kuo-Yung, the spokesperson for the Taiwanese government, said in a news conference shown on CNN affiliate SET TV.

Hsu Kuo-Yung said the railway department hasn’t given a full status report of the damage yet but he said it seems the railways have not been damaged much. Some roads have also been damaged.

‘Nerves are jangled’

Laura Lo, a worker at the 7-Eleven convenience store across the street from the Marshal Hotel, said the first and second floors of the hotel appeared to be severely damaged and police officers were conducting rescue operations there.

Her store also suffered broken glass from the quake, she said, and many roads in the area were closed.

An employee at the Park City Hotel down the street told CNN that he felt the quake but there was no damage at his location.

Margaret K. Lewis, a Seton Hall University Law School professor living in Taipei, said she felt prolonged swaying at her modern high-rise apartment building in Beitou District, in the northern part of the city.

“Nothing broken, and two children slept peacefully through the event. We have since felt a few mild aftershocks,” Lewis said in an email. “Nerves are jangled, but otherwise all appears well. I have not been outside to look for damage, but my expectation is that my area is generally fine.”
