探测和监测滑坡的早期预警系统(EWSS)是一个巨大的挑战。由于灾难性山体滑坡的高成本，它们很重要，而且具有挑战性，因为很难确定各种引发滑坡的因素。虽然取得的成功数量非常有限，但从地面、飞机和太空进行的地球观测(EO)的最新进展极大地提高了我们探测和监测活跃山体滑坡的能力。越来越多的岩土工程理论表明，破坏前的行为可以为即将发生的灾难性破坏的位置和时间提供线索。在本文中，我们以中国最近的两个滑坡为例，证明了卫星雷达观测可以用来探测灾难性滑坡的变形前兆，并且可以通过实时的现场观测来实现早期预警。我们提出了一个新颖和令人兴奋的框架，利用EO技术来构建一个可操作的滑坡EWS。
Early warning systems (EWSs) to detect and monitor landslides are a great challenge. They are important due to the high cost of catastrophic landslides and are challenging because of the difficulty in identifying a diverse range of landslide-triggering factors. While there has been a very limited number of successes, recent advances in Earth observation (EO) from the ground, aircraft, and space have dramatically improved our ability to detect and monitor active landslides. A growing body of geotechnical theory suggests that prefailure behavior can offer clues to the location and timing of impending catastrophic failures. In this article, we use two recent landslides in China as case studies to demonstrate that satellite radar observations can be used to detect deformation precursors to catastrophic landslides and that early warnings can be achieved with real-time, in situ observations. We propose a novel and exciting framework that employs EO technologies to build an operational landslide EWS.
