How do I get earthquake hazard maps for locations outside of the U.S.?

We know of no current "zone" designations for sites outside of the United States. For locations outside the United States for which seismic design is required for military facilities, there exists a standard based on probabilistic spectral ordinates in the manner of the International Building Code and are declared to reflect the 2015 version of that code. These spectral ordinates can be found in the document "UFC 3-301-01, Unified Facilities Criteria (UFC), Structural Engineering." We know of a version representing a date as late as September 2016. You can obtain this document by Googling this string: UFC 3-301-01, September 2016. The spectral ordinates can be found in Table F-3.

A seismic zone is used to describe an area where earthquakes tend to focus; for example, the New Madrid Seismic Zone in the Central United States. A seismic hazard zone describes an area with a...
