SAN FRANCISCO, Dec. 18 (UPI) -- Doorknob hangars saying "Be Tsunami Ready" are being distributed throughout San Francisco to coincide with updated inundation maps, officials said.
The hangars, printed in English and Chinese, show a map of the areas likely to be swamped by a major tsunami, including all of Ocean Beach east to 46th Street and the zoo.
Newly updated inundation maps released Thursday by the state cover shorelines in 30 California coastal communities and show every harbor and inlet that would be threatened by a major sea wave, The San Francisco Chronicle reported Friday.
Major earthquakes along the Aleutian islands in Alaska could trigger tsunamis as far south as California. The 1964 Alaskan quake, with a magnitude of 9.2, killed 11 people in California when it sent waves 7 to 21 feet high between Crescent City and Monterey, state geologist John Parrish said.
"The danger is always present, and it could be worse," Parrish told the Chronicle.
