Prepared by the Tsunami Loads and Effects Subcommittee of the Minimum Design Loads for Buildings and Other Structures Standards Committee of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCE
ASCE 7-16 Tsunami Design Zone Maps for Selected Locations provides detailed maps for 62 locations that fall within the Tsunami Design Zone in the United States. As defined in Chapter 6, "Tsunami Loads and Effects," of Standard ASCE 7-16, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, the Tsunami Design Zone consists of the land area between a coastline and the inundation limit line, within which structures are analyzed and designed for inundation by the maximum considered tsunami. Engineers can use these maps to determine quickly whether a structure falls within the Tsunami Design Zone, as indicated by red shading.
For the purpose of identifying the Tsunami Design Zone, these high-resolution PDF maps are considered equivalent to the results served from the ASCE Tsunami Design Geodatabase, http://asce7tsunami.online, and are produced with the runup, GIS point data, and Tsunami Design Zone data in the Geodatabase. Five US states contain a Tsunami Design Zone: Alaska, California, Hawaii, Oregon, and Washington. A Location Key Plan for each state identifies specific areas that have PDF maps; these Location Key Plans correlate to Figures C6.1-1(a) to (i) in Standard ASCE 7-16.
Also included is a report, "Probabilistic Tsunami Design Maps for the ASCE 7-16 Standard," which was prepared for the Structural Engineering Institute by researchers developing the Tsunami Design Geodatabase. This report describes the development of the 2,500-year probabilistic Tsunami Design Zone maps and is suitable as a user's manual.
Structural engineers, architects, and building code officials will find this collection of maps useful in identifying locations that fall within the Tsunami Design Zone as defined by ASCE 7-16.
