California has experienced notable seismic events in the past year:

April 14, 2025: A magnitude 5.2 earthquake struck near Julian in San Diego County, felt as far north as Los Angeles. No significant damage was reported, but it served as a reminder of the region's seismic vulnerability. Los Angeles Times+3The Guardian+3The US Sun+3
December 5, 2024: A magnitude 7.0 earthquake occurred off the coast of Northern California near Cape Mendocino. The quake prompted a tsunami warning, later canceled, and caused power outages and minor structural damages in Humboldt County. Wikipedia, la enciclopedia libre
February 15, 2025: Two earthquakes exceeding magnitude 3.5 were recorded northwest of Malibu, contributing to the series of seismic activities in Southern California. CBS News

These events underscore the continuous seismic activity in California and the importance of preparedness.

Despite California's high seismic risk, earthquake insurance coverage remains relatively low:

Coverage Rate: Approximately 10% of California residents have earthquake insurance. The North Bay Business Journal+1CBS 8+1
Policy Details: Earthquake insurance typically includes deductibles ranging from 2% to 20% of the insured property's value, which can be a deterrent for some homeowners. NAIC
Recent Changes: The California Earthquake Authority has raised rates by an average of 6.8%, reflecting increased construction costs and risk assessments. CBS 8

The low uptake of earthquake insurance could lead to significant financial strain on individuals and the state in the event of a major earthquake.

Casualties: 57 deaths and over 9,000 injuries. ScienceDirect+2Wikipedia+2San Fernando Sun+2
Economic Loss: Estimated at $40 billion in 1994 dollars, which is approximately $85.7 billion when adjusted to 2025 values. Wikipedia

If a similar earthquake were to occur today:

Insurance Coverage: With only about 10% of homeowners insured, a vast majority would bear the full brunt of repair and rebuilding costs.
State and Federal Aid: The financial burden on government resources would be substantial, potentially diverting funds from other critical areas.
Economic Disruption: Infrastructure damage could lead to significant business interruptions, job losses, and long-term economic downturns in affected regions.

The combination of low insurance coverage and high potential damages highlights a significant vulnerability in California's disaster preparedness.

To mitigate the risks and potential economic fallout of major earthquakes:

Increase Public Awareness: Educational campaigns to inform residents about the benefits and costs of earthquake insurance.
Incentivize Insurance Uptake: Subsidies or tax incentives for homeowners who purchase earthquake insurance or retrofit their homes for seismic safety.
Enhance Building Codes: Strengthen regulations to ensure new constructions are more resilient to seismic activity.
Emergency Preparedness: Encourage residents to develop and maintain emergency kits and plans.
Infrastructure Investment: Allocate funds to reinforce critical infrastructure, such as bridges and utilities, to withstand earthquakes.
