Over a decade has passed since Hurricane Katrina brought destruction to New Orleans and the Gulf Coast, leaving 1,245 dead and $108 billion in property damage. More than a million people were displaced and communities destroyed. The region has come a long way since then, but it will never be the same. Katrina remains the country’s worst natural disaster. Here in Southern California, earthquakes, rather than hurricanes, pose risks to our lives, health, and socioeconomic futures. The risks are more pronounced in dense areas — places where there are more people and infrastructure that can be affected.
