ABSTRACT

Guidelines for Design of Structures for Vertical Evacuation from Tsunamis   [open pdf - 7MB]

"The project was undertaken to address the need for guidance on how to build a structure that would be capable of resisting the extreme forces of both a tsunami and an earthquake. This question was driven by the fact that there are many communities along our nation's west coast that are located on narrow spits of land and are vulnerable to a tsunami triggered by an earthquake on the Cascadia subduction zone, which could potentially generate a tsunami of 20 feet in elevation or more within 20 minutes. [...] This publication presents the following information: (1) General information on the tsunami hazard and its history; (2) Guidance on determining the tsunami hazard, including the need for tsunami depth and velocity on a site-specific basis; (3) Different options for vertical evacuation from tsunamis; (4) Determining tsunami and earthquake loads and structural design criteria necessary to address them; and, (5) Structural design concepts and other considerations."
