The city of Arena Cove , which has changed little during the 19th and 20th centuries , is no stranger to natural disasters . The city and the Point Arena Lighthouse were damaged during the 1906 San Francisco earthquake , and the wharf was damaged beyond repair during severe storms in 1983 and was rebuilt in 1986 . Distant earthquakes have created danger in the form of tsunami , but only mild effects have been observed . A wave arrived at the cove following the 1946 Aleutian Islands earthquake and a wave arrived after the 1964 Alaska earthquake
