Huihui Weng

Associate Professor, weng@nju.edu.cn

His research vision is to achieve a fundamental understanding of fault mechanics, through synergistic efforts in combining theoretical, computational, laboratorial, and observational approaches. His long-term goals aim at answering the following essential questions: What controls the nucleation, propagation, and arrest of earthquake ruptures? Can we anticipate the size of future earthquakes? What controls the slow and fast earthquake cycle? How can we improve the way seismic risk is evaluated?

Research

A new theory connects slow and fast earthquakes

We propose a new model to elucidate the fundamental connections between slow and fast earthquakes.

A new model found to predict earthquake propagation speed

We propose a new model predicting continuum of earthquake rupture speeds due to oblique sliding.

New theory for elongated ruptures

We develop a new 3D theory to describe the rupture propagation in a fault with finite width.

Dynamic rupture simulation for the 2015 Mw7.8 Nepal earthquake

How can we constrain the frictional parameters on the fault?
