When to flee on foot


An interactive map from the California Geological Survey shows which neighborhoods in the Bay Area must be evacuated on foot in the event of a tsunami risk.

When zoomed out, the map appears to show the land of the Bay Area in green and the surrounding water in yellow. But zoom in and you can see some coastal areas are in the yellow zone as well – and those are the most tsunami risk areas after a big earthquake.

“If you find yourself in the yellow danger zone, immediately evacuate on foot to a green zone after feeling a long-lasting earthquake,” the map advises.

Some areas near the baylands or the beach are notorious for staying put – the headquarters of Facebook and Oracle, for example, and the San Francisco Airport.

But if your home or work is in the yellow zone, the agency encourages you to chart your route to safety. Among these places:

  • Oracle Park and Chase Center. At the first, you just have to go to King Street.
  • Many San Francisco waterfront attractions including the Ferry Building, Pier 39, and Crissy Field.
  • All the treasure island. But Yerba Buena Island is in the green.
  • Most of Alameda.
  • Oakland International Airport.

The new map portions update the information for Santa Clara, San Francisco, Contra Costa, San Luis Obispo, Santa Barbara, and Orange counties. Thirteen of the state’s 20 coastal counties now have updated maps. For more information, visit the CGS website.
