Effects of Tsunamis in the Gulf of Alaska

这项研究项目通过验证海啸预测模型和估计阿拉斯加和加拿大(北太平洋沿岸地区)沿岸海啸的可能影响，提高了对海啸破坏的工程学理解。众所周知，这些地区容易发生大地震和随后的海啸。这项研究提供了一种系统的方法来了解阿拉斯加湾附近人口最稠密地区的海啸助推特征，这些地区在可能发生的海啸范围内。一个与时间相关的二维数值模型将被开发出来，以研究阿拉斯加近海大地震引发的海啸的产生和传播。然后，将根据阿拉斯加海啸预警中心(ATWC)和不列颠哥伦比亚省悉尼海洋科学研究所提供的该地区的实际海啸数据，以及西雅图太平洋海洋环境实验室(PMEL)关于该地区深海测量的数据来验证结果。

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.
