Rescue services search for people in a damaged building in Hualien, eastern Taiwan, 07 February 2018, after a magnitude 6 quake hit Hualien on the night of 06 February 2018.
The magnitude 6.4 quake, which hit near the coastal city just before midnight on Tuesday, injured 260 people and caused four buildings to collapse.
Nervous residents endured more than 200 aftershocks, including a 5.7 quake late yesterday and smaller tremors early this morning.
Firefighters climbed ladders hoisted against windows to reach residents inside apartments.
The force of the tremor buckled roads and disrupted electricity and water supplies to thousands of households, the fire agency said.
Mainland Chinese, Czech, Japanese, Singaporean and South Korean nationals were among the injured.
"With the solidarity and affection that characterizes the relations between our peoples and governments, we want to convey to you (President Tsai Ing-wen) and to the grieving families, the most heartfelt condolences", the Nicaraguan government said in a statement.More news: Pentagon confirms it is planning a huge military parade

Rescue efforts are underway in the city as emergency workers and volunteers work to shift rubble and search for trapped people.
But the mountains that rise up behind the city - and bestow Taiwan's east coast with such majestic beauty - are a testament to the deadly tectonic fault lines that run through the island. A major focus of the rescue effort was a residential building tilted at about a 40-degree angle.
Tsai said she "ordered search and rescue workers not to give up on any opportunity to save people, while keeping their own safety in mind". Residents were directed to shelters where they were provided with food, water and a place to sleep.
Speaking from a crisis centre in Taipei, cabinet spokesperson Hsu Kuo-yung said rail links appeared to be unaffected and the runway of Hualien airport was intact.
"We discovered the body of a Chinese woman at the hotel in Yun Tsui (building) earlier this morning and located another person who's a hotel staffer", he said.
Latin America has offered its condolences to Taiwan, after the Chinese region was struck by a 6.4 magnitude quake late Tuesday. Five people involved in the construction of the complex were found guilty of negligence and given prison sentences.
