Earthquake damage in Oregon: Preliminary estimates of future earthquake losses by Yumei Wang has been released as DOGAMI Special Paper 29. Wang, a geotechnical engineer, analyzed all faults with a 10% chance of causing an earthquake in the next 50 years and projected potential damage. Wang stresses that these are preliminary figures. "There are two things we could not incorporate into this study that would significantly increase these figures. One is a tsunami. The other is an inventory of unreinforced brick or masonry buildings." The cost of the report is $10. Buy

Using Earthquake Hazard Maps. A Guide for Local Governments in the Portland Metropolitan Region has been released as DOGAMI Open-File Report O-98-04. It was prepared by Spangle Associates, Urban Planning and Research of Portola, California, for Metro, the regional government for the Portland metropolitan area, and originally published by Metro. This guide describes how local governments use earthquake hazard maps prepared by DOGAMI to reduce damage and losses in earthquakes. It is addressed to local government staff and elected and appointed officials who regulate the use and development of land and construction of buildings and prepare for and manage disaster response and mitigation. The guide focuses on local government actions but recognizes that all levels of government, businesses, community organizations, households, and individuals play roles in reducing a community's vulnerability to earthquakes. The cost of the report is $10. Buy

An introduction and explanation are contained in a text file. Over 15,000 earthquakes are included in the database, which was compiled from a variety of databases covering the Pacific Northwest. Depending on the completeness of the record, each earthquake record includes data on date and time of the event, location and depth of the epicenter, magnitude and intensity of shaking, source of data, and information on the quality of determinations of location and magnitude of the earthquake. When used in a database software program, this catalog can be searched to find earthquakes by size, time, and geographic area. Price of this report is $10. Buy
