Exploring structural controls on great earthquake rupture and architecture of the Sumatra-Andaman convergent margin: A regional seismic reflection survey in collaboration with the

该项目将在2008年nerc赞助的前往受2004年12月苏门答腊地震影响地区的游轮上进行为期7天的MCS附加活动。要验证的假设是，向陆向（与向海向相反）的逆冲促进了变形前沿的破裂，从而有可能发生海啸性地震。结果表明，苏门答腊地区存在这种向陆向向的逆冲构造，并通过对地震资料的收集和分析提出了约束其变形样式的建议。根据英国/NERC的合同，这些数据将作为德国船只的附加设备收集。更广泛的影响包括对世界上一个产生海啸的非常易震地区有了更深入的了解，并与国际（英国和德国）科学家进行了明显的社会关联和合作。此外，pi将努力让代表性不足的学生参与研究。

This project will conduct a 7-day MCS add-on to a 2008 NERC-sponsored cruise to the area affected by the December 2004 Sumatran earthquake. The hypothesis to be tested is that landward-vergent (as opposed to seaward-vergent) thrusting promotes rupture to the deformation front, and consequent possibility for tsunamigenic earthquakes. The PIs suggest that such landward-vergent thrusting is present in the Sumatra area, and propose to constrain the deformation style by collection and analysis of seismic data. The data will be collected as an add-on to a German vessel under contract to UK/NERC.Broader impacts include greater understanding of a very seismogenic area of the world that produces tsunamis with the obvious societal relevance and collaborations with international (UK and German) scientists. In addition the PIs will make an effort to get underrepresented students involved in the study.
