我的研究方向是与流体有关的地震学现象,称之为流体地震学或地震流体力学。地球表面71%的面积被海洋所覆盖,在海洋中经常使用海底压强计、海底地震仪等仪器进行地震学观测,观测数据的成因机制常常涉及较多的流体力学过程,因此数据的理论解析及应用成为难点。研究目标是深刻理解观测数据中伴随的流体力学现象、准确解析数据中包含的地球科学学信息。具体的研究内容包括:海啸及海啸预警、海底压强数据、海底地震仪噪声。

① 海啸及海啸预警

        * 俯冲带地震海啸的耦合生成过程,水内声波的观测及其在海啸预警方面的应用

        * 海啸反演,海啸数据对地震破裂的约束

        * 海啸灾害的概率性评估,考虑区域地质构造条件对海啸概率评估的影响

 海底压强

        * 海啸压强数据的成因机制及其理论解,海底压强计的仪器设计

        * 海底压强数据的应用

③ 海底地震仪的噪声

        * 海底地震仪受到海洋水波、海底洋流产生噪声的力学机制、降噪方法

        * 海底地震仪噪声数据的应用,反推海底洋流信息

(1) Tsunami Downloader

These Python scripts download and display tsunami data from NOAA and IOC. It will be convenient to check if tsunamis are generated after an earthquake.

(2) pcomcot

pcomcot solves linear and nonlinear shallow water wave equatios to simulate the generation, propagation and runup of tsunami waves. It is parallelized using MPI, and can use multiple nested grids. The algorithm and codes are developed based on the COrnell Multigrid COupled Tsunami package (COMOCT). This released version is tested against a few benchmarks, and it is stable, although the user manual needs further improvements.
