While earthquakes are a major geologic hazard, many outstanding questions remain about the mechanisms that control their occurrence, magnitude and frequency. Society and the economy are affected not only by large tectonic earthquakes, but also moderate-size events induced by human activities such as resource extraction. By integrating geophysical observations with numerical modeling, Prof. Liu's research program investigates the source mechanism of natural and anthropogenic earthquakes, focusing on processes that operate across timescales and in various types of tectonic settings. The research outcomes of this program will promote the transition from conceptual understanding towards quantitative prediction of earthquakes and hazard assessment.

虽然地震是一种主要的地质灾害，但关于控制地震发生、震级和频率的机制仍然存在许多悬而未决的问题。社会和经济不仅受到大型构造地震的影响，而且还受到人类活动（例如资源开采）引发的中等规模事件的影响。通过将地球物理观测与数值模拟相结合，刘教授的研究项目研究了自然和人为地震的震源机制，重点关注跨时间尺度和各种构造环境的过程。该项目的研究成果将促进地震和灾害评估从概念性理解向定量预测的转变。
