A 6.1-magnitude earthquake jolted Taiwan on Thursday, the US Geological Survey said, shaking buildings and disrupting traffic.
In the capital Taipei, highrises swayed while some panicked schoolchildren fled their classrooms in eastern Yilan county, according to reports.
The quake was felt across the island and a highway connecting Yilan and Hualien was shut down due to falling rocks, authorities said.
An official at the Hualien county fire department told AFP that two people, including a male Malaysian tourist, were injured by falling rocks and that the department was planning to send in medics by helicopter.
