Tsunami Hazard Assessment Special Series: Vol. 1, Tsunami Hazard Assessment for Guam

摘要

Several Pacific Ocean Basin tsumanis occurred in the mid 20th century, causing oestruction to United States coastal communities over a wide spatial scale. The destruction and unpredented loss of life following the December 2004 Sumatra tsunami provided a reminder of the potential hazard posed to coastal communities and served as the catalyst for the formation of a partnership between the Pacific Risk Management 'Ohana and the National Oceanic and Atmospheric Administration Center for Tsunami Research. The goal of this partnership is to conduct comprehensive tsunami hazard assessments for Pacific communities within the United States and her territories in support of hazard mitigation efforts that leverage multi-level agency collaboration for the benefit of the Pacific community 'Ohana (or family). Of the specific communities identified for tsunami hazard assessment, the island of Guam was chosen as the pilot study with the goal of identifying earthquake sources with the greatest potential to impact Guam, its population, and economy. The scope of this study includes five tsunami-vulnerable sites along the coastline of Guam for which 725 probable earthquake scenarios are considered.
