Nineteen years later, inwards 1993, western Oregon adopted its origin seismic standards. Franz Rad, a professor of civil & environmental technology scientific discipline at Portland State University, argues that these dates furnish a "broad-brush hold back at the vulnerability of buildings".
Earthquakes: How Vulnerable are Portland’s Buildings? uses Portland edifice historic catamenia information to assess which buildings are most earthquake prone. Building footprints are colored on the map to demo buildings constructed earlier 1974, those buildings constructed from 1974 - 1993 as well as buildings erected after 1993. You tin thence purpose the map to assess the ('broad-brush') vulnerability of whatever Portland edifice to earthquake damage.
