East Helanshan Fault, northern China

Welcome Guest   ( Sign In )

Overview

This dataset contains a 100 km long section of the East Helanshan Fault on the western side of the Yinchuan Graben in northern China. This fault was the site of the devastating 1739 Yinchuan earthquake. Surface fault scarps are visible in the point cloud for much of the fault length. The point cloud data were constructed via photogrammetric methods from data acquired by Airbus Defence and Space (Pleiades 1A) and funded by the Natural Environment Research Council (NERC), UK.
