This research program advances understanding of earthquake processes at scales from tsunamigenic megathrusts to induced seismicity and improves seismic hazard mitigation and response in Canada and worldwide. In the long-term, this knowledge will contribute to the fundamental understanding of earthquake cycles. Tsunamigenic earthquakes are a major hazard, as tragically documented by devastating events (e.g. Indian Ocean, Japan). While high-quality data are increasingly available, significant gaps in methods and understanding exist. Although induced earthquakes are not associated with devastation, significant concerns exist that they can cause damage and little is known about the governing processes and scales.

该研究项目促进了对地震过程的理解，从海啸引发的特大逆冲到诱发的地震活动，并改善了加拿大和世界范围内地震灾害的缓解和反应。从长远来看，这些知识将有助于对地震周期的基本理解。海啸性地震是一种主要的灾害，正如毁灭性事件（如印度洋、日本）所悲惨记录的那样。虽然高质量的数据越来越多，但在方法和理解上存在重大差距。虽然诱发地震与破坏无关，但人们仍然非常担心它们会造成破坏，而且人们对其控制过程和规模知之甚少。
