Death toll rises to 13 after three bodies found on hiking trail. Helicopters continue to evacuate tourists trapped by landslides.

More than 600 people still stuck in tunnels or areas isolated by landslide. 84 buildings were "severely damaged" by the earthquake, most of them in Hualien County, a city of 100,000 on the eastern coast and located about a hundred kilometers southeast of the capital Taipei. Wednesday's earthquake was the largest to hit Taiwan since a 7.6 magnitude earthquake in 1999.
