California Tsunami Risk: Understanding the Threat and Preparing

In-Depth Analysis

California's diverse coastline faces varying tsunami risks, influenced by both distant and near-source events.

**Southern California:** A magnitude 9.3 earthquake in Alaska could send 15-foot waves to Marina del Rey and Santa Monica Pier. Near-source events could bring 30-foot waves to Catalina Island. The city of Los Angeles has an estimated 23,000 residents in the tsunami hazard area, while Long Beach has 31,000.

**Central Coast:** Santa Cruz and Monterey counties could see tsunamis within minutes of underwater landslides. A near-source tsunami could bring waves of up to 15 feet in the city of Marina.

**Bay Area:** A distant-source tsunami could result in waves of 32 feet at Ocean Beach in San Francisco and 31 feet in Pacifica. More than 1,300 people could be injured or killed if evacuation is delayed by just 30 minutes.

**North Coast:** Del Norte and Humboldt counties face significant risk from the Cascadia subduction zone. Flooding could reach up to 50 feet in Crescent City.
