Huadong Valley

The Huadong Valley, also called the Hualien-Taitung Valley or East Longitudinal Valley, is a long narrow valley between the Central Mountain Range and the Coastal Mountain Range of eastern Taiwan, running about 180 kilometers from Hualien City in the north to Taitung City in the south. It is believed to mark the northern terminus of the Philippine Mobile Belt, a tectonic boundary zone, and its floor is built from the alluvial plains of the Hualien, Xiuguluan and Beinan rivers, which all flow into the Pacific Ocean.
