The Applied Technology Council is a nonprofit research organization based in California which studies the effects of natural hazards on the built environment and how to mitigate these effects, particularly earthquakes. It was founded through the efforts of the Structural Engineers Association of California in 1973. [1]
In addition to evaluating earthquake hazard following notable changes in seismic activity, CEPEC is also tasked with evaluating earthquake predictions. For example, CEPEC evaluated the 2004 earthquake prediction by Keilis-Borok [5] and a 2015 prediction following the La Habra earthquake [6] and concluded that no action should be taken as a ...
The Alder Creek Bridge in Manchester, California, is located within an Alquist-Priolo Earthquake Fault Zone. [ 2 ] Buildings built before 1972 may still lie on top of active faults, and those buildings can remain where they were originally built, unless they undergo a major remodel where more than 50% of the building changes.
Earthquake modification techniques and modern building codes are designed to prevent total destruction of buildings for earthquakes of no greater than 8.5 on the Richter Scale. [4] Although the Richter Scale is referenced, the localized shaking intensity is one of the largest factors to be considered in building resiliency.
Crews work on a portion of a 104-inch diameter earthquake-resistant ductile iron pipe on the Colorado River aqueduct recently. The pipe was added to the five-mile-long Casa Loma Siphon system that ...
The 2015 Uniform California Earthquake Rupture Forecast, Version 3, or UCERF3, is the latest official earthquake rupture forecast (ERF) for the state of California, superseding UCERF2. It provides authoritative estimates of the likelihood and severity of potentially damaging earthquake ruptures in the long- and near-term.
Fire insurance has become more costly—if it's available at all—in California, leading more Golden State homeowners to turn to the FAIR Plan, a government-backed insurer of last resort.
Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes.With better understanding of seismic demand on structures and with recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged.
