This project addresses three important aspects of the neotectonics of the Himalayan foothills and adjacent plains of India-the long-term slip rate on the plate boundary fault, the recurrence interval for great Himalayan-front earthquakes and the amount of strain released within the Himalaya rather than the Himalayan front. The work involves construction of balanced sections using surface outcrops, drilling and seismic reflection profiles, mapping of Quaternary deposits, trenching and geomorphic analysis of river profiles. This research is in collaboration with the Wadia Institute of Himalayan Geology and the Oil and Natural Gas Commission of India. Results are a fundamental interest and of considerable utility in assessment of potential earthquake hazards in the Himalayan Foothills of northwest India.

该项目研究了喜马拉雅山麓和邻近印度平原新构造运动的三个重要方面——板块边界断层的长期滑移率、喜马拉雅前缘大地震的复发间隔以及喜马拉雅山内部而不是喜马拉雅前缘释放的应变量。 这项工作包括利用地表露头、钻孔和地震反射剖面构建平衡剖面、第四纪沉积物测绘、挖沟和河流剖面地貌分析。 这项研究是与瓦迪亚喜马拉雅地质研究所和印度石油和天然气委员会合作进行的。 结果对于评估印度西北部喜马拉雅山麓的潜在地震危害具有重要意义和相当大的实用性。
