Venezuela quake: Devastation is urgent warning for California

Key Points:

• Two powerful earthquakes of magnitudes 7.2 and 7.5 struck Venezuela near Caracas, causing at least 188 deaths, nearly 1,500 injuries, and widespread destruction, particularly collapsing non-ductile concrete buildings vulnerable to seismic shaking.
• Non-ductile concrete buildings, lacking sufficient steel reinforcement, have historically caused significant fatalities in earthquakes, including in California during the 1971 Sylmar and 1994 Northridge quakes, prompting updated building codes and retrofit requirements in some California cities.
• Despite improvements in seismic safety codes for new construction, many older concrete buildings in California remain vulnerable due to lack of retrofitting, posing a serious risk in a major earthquake similar to those recently experienced in Venezuela.
• The seismic risk in Caracas is comparable to that of Los Angeles and San Francisco, with similar tectonic plate movements and earthquake potential, underscoring the importance of preparedness, retrofitting, and community planning in California.
• Residents are encouraged to retrofit vulnerable buildings, secure household items, store emergency supplies, and develop family and neighborhood earthquake response plans to mitigate damage and enhance safety during future seismic events.
