UC’s Seismic Ratings. UC’s seismic performance ratings for earthquake resiliency are based on the existing California buildings code. The ratings levels are: I - IV = Compliant with the UC Seismic Safety Policy. V = Will require further evaluation and, if rating is confirmed, must be addressed in order of priority. VI = Priority for improvement
Early earthquake warning systems typically use seismometers to detect incoming fast P-waves. When shaking is felt, a signal is sent to the local seismic authority, which rapidly sends out an alert to those in the region who are likely to feel shaking, hopefully before the more damaging S-waves arrive.
Current approaches in seismic design for new buildings, and proposed earthquake ratings systems for existing buildings, consider each building individually, without interaction with its neighbors.
