主要从事震源破裂过程、活动构造、及构造应力场解析等研究。在日本攻读博士期间,主要利用高密度地震台网数据,系统分析了近年来全球大震震源的破裂过程及关键震源参数,比如破裂速度、破裂尺度、和持续时间等,发现了超剪切破裂在大型走滑断层型地震中存在的普遍性,提出并发展了一种新的震源成像方法。博士毕业后,主要从事基于全球实时地震观测数据流的大震破裂过程自动分析方法及软件研制。独立设计开发了一套从获取实时数据流、数据校验、并行计算、到结果输出及网站展示的浅源大地震(Mw≥7.5)震源破裂和信息发布系统。该系统目前已在中国地震局等机构运行测试和应用。近年来基于台阵技术,提出并论证了一种新的大震震级标度和快速测定大震破坏场的方法,其成功推广可能为快速准确地震救援和海啸预警提供基础。发表学术论文共计30余篇,主要发表在国际重要地学SCI期刊如EPSL、JGR、GRL、BSSA等主流杂志,被国际主流杂志广泛引用。
目前主要研究方向为:
1. 实时地震学
基于近年来全球密集地震台网,系统研究地震震源物理过程。并基于实时地震数据流,探索快速地震减灾及海啸预警新方法。
2. 诱发地震
基于地震震源机制、地震精定位等手段,研究三峡地区微震的发震应力场及区域构造应力环境,及其与库水渗流场变动的关系。
3. 大震破裂过程分析
持续追踪近年来大震破裂过程特征,开发震源破裂研究新方法,深入认识大震破裂过程及其特征。
