This research project improves an engineering understanding of the tsunami damage by verifying tsunami predictive models and estimating the possible effects of tsunamis along the coast of Alaska and Canada (Northern Pacific Coastal region). These areas have been known to be prone to large earthquakes and subsequent tsunamis. This study provides a systematic approach to understand the tsunami runup characteristics for the most densely populated regions near the Gulf of Alaska which are within the reach of a possible tsunami. A time-dependent, two-dimensional numerical model will be developed to study the generation and propagation of a tsunami from a major earthquake offshore of Alaska. The results will then be verified based on actual tsunami data in this region which are available from the Alaska Tsunami Warning Center (ATWC) and from the Institute of Ocean Sciences in Sidney, B.C., and the data on deep sea measurements of the region from the Pacific Marine Environmental Laboratory (PMEL) in Seattle.

该研究项目提高了对 通过验证海啸预测模型和估算海啸损失 海啸沿着阿拉斯加和加拿大海岸可能造成的影响 （北方太平洋沿岸地区）。 这些地区被认为是 容易发生大地震和随后的海啸。 本研究 提供了一个系统的方法来了解海啸的上升 墨西哥湾附近人口最稠密地区的特点 阿拉斯加可能会发生海啸。 一 将建立一个随时间变化的二维数值模型， 研究海啸的产生和传播， 阿拉斯加近海地震 结果将根据 该地区的实际海啸数据，可从 阿拉斯加海啸预警中心（ATWC）和海洋研究所（Institute of Ocean） 悉尼，不列颠哥伦比亚省，和深海测量数据， 太平洋海洋环境实验室（PMEL） 西雅图。
