While California's latest tsunami warning in Half Moon Bay prompted widespread evacuations, the state has experienced several notable tsunami events throughout its history. Here's a look at some of the most memorable tsunamis that have impacted California's shoreline.
1964 Alaska Tsunami A massive 9.2 earthquake in Alaska triggered powerful waves that struck Northern California, causing extensive damage to Crescent City. The tsunami killed 12 people and destroyed much of the city's downtown area.
1960 Chilean Tsunami Following a 9.5 magnitude earthquake in Chile, tsunami waves reached California's coast roughly 15 hours later. While damage was limited, the event demonstrated how distant earthquakes could impact California's shores.
2011 Japan Tsunami The devastating earthquake and tsunami in Japan sent waves across the Pacific, causing approximately $100 million in damage to California harbors and marinas. Santa Cruz and Crescent City were particularly affected.
1927 Point Arguello A local earthquake generated tsunami waves that struck the central California coast near Lompoc. While relatively small, this event highlighted that local seismic activity could create tsunami conditions.
2022 Tonga Volcano The underwater volcanic eruption in Tonga created tsunami waves that reached California, causing minor flooding and strong currents in coastal areas, particularly affecting harbors and marinas.
These historic events have shaped California's tsunami preparedness systems, including evacuation protocols and warning systems that continue to protect coastal communities today.
