Chinese and American scientists have deployed an airborne LiDAR and 3D system to map the Haiyuan fault zone in Asia. The equipment uses laser light pulses to gauge distances and map components of the terrain. It's creating the most precise calculations of the fault zone. "In the future, we can expect that more and more concepts or models of fault activity would benefit from this unprecedented survey technique," the scientists say. Eventually they hope to be able to "assess potential risk for future earthquake hazards."
