China's Launching Drones to Fight Back Against Earthquakes

The 1556 earthquake that killed an estimated 830,000 people in the Shaanxi Province is but the deadliest example of China's long history with the natural disaster. The 1920 Haiyuan quake killed 273,000; the 1976 Tangshan earthquake claimed about 232,000 lives. Whether or not they hold to the historic view that earthquakes indicate heaven's displeasure, the modern Chinese aren't sitting idle as the ground trembles. Starting in the mid-1960s, the country established a system to improve prediction capabilities, response training, and public communications to reduce the impact of calamities. They enlisted satellites to shape post-disaster responses, but since quakes have a habit of knocking out the ground-based systems that deliver their images to those who need them, a view from space isn't always much help.
