This is kind of interesting. The equivalent of the Oregon Geologic Survey, DOGAMI, has a geologic hazard map of the state that the City of Newport has used as the basis for a geologic hazard building code. This article describes some Recent and proposed changes to that code.

But I found it interesting that the City Council approved a motion to only display the hazard maps in grayscale at City Meetings because the red color used on the DOGAMI map for high risk areas might scare people off from buying a property.
