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.

该项目介绍了喜马拉雅山麓新山麓的新遗传学的三个重要方面和印度的相邻平原 - 板边界断层的长期滑移速率，大喜马拉雅 - 弗朗特地震的复发间隔以及喜马拉雅省内释放的压力量比喜马拉雅阵线。 这项工作涉及使用表面露头，钻孔和地震反射曲线，第四纪沉积物的映射，沟槽和河流剖面的地貌分析来构建平衡部分。 这项研究与瓦迪亚喜马拉雅地质学院和印度石油和天然气委员会合作。 结果是评估印度西北部喜马拉雅山麓丘陵的潜在地震危害的基本利益和相当大的效用。
