Editing Ferndale, California (section)

===Earthquakes===
Ferndale's location near the [[Mendocino triple junction]], a [[subduction]] fault associated with the offshore interaction of the [[Pacific Plate|Pacific]], [[North American Plate|North American]], and [[Gorda Plate|Gorda]] [[Plate tectonics|tectonic plates]], makes it extremely susceptible to [[earthquake]]s. Earthquakes affected Ferndale in the 19th century, but the first to receive widespread news coverage was the [[1906 San Francisco earthquake]], which damaged more than 40 structures in the downtown, with severe damages to the two brick buildings, and 98 percent of chimneys thrown down. The earthquake was estimated at a [[Mercalli intensity scale|Mercalli intensity]] of VII (''Very strong'') at Ferndale.<ref name="Dengler">{{cite journal  | last =Dengler  | first =Lori  | title =The 1906 Earthquake on California's North Coast | journal =Bulletin of the Seismological Society of America  | volume =98 | issue =2  | pages =918–930   | date =April 2008   | url =http://bssa.geoscienceworld.org/content/98/2/918.full | doi = 10.1785/0120060406| bibcode =2008BuSSA..98..918D}}</ref>

On January 22, 1923, a 7.2 [[Richter magnitude|magnitude]] [[List of earthquakes in California|earthquake]] centered off [[Cape Mendocino]] was said to be nearly as great a shock in Ferndale as the 1906 earthquake and produced a [[tsunami]].<ref>{{citation|last1=Stover|first1=C.

Smaller earthquakes were recorded from the 1920s through the 1980s, but the next big earthquake to strike Ferndale was actually three earthquakes collectively named the [[1992 Cape Mendocino earthquakes]].

Almost 2 years after that earthquake, on December 5, 2024, the [[2024 Cape Mendocino earthquake]] struck the city. With a magnitude of 7.0, and having an epicenter of only 62 miles (100&nbsp;km) southwest of Ferndale, the earthquake was felt in the city and the rest of [[Humboldt County, California|Humboldt County]]. It also sparked a tsunami warning, but due to the nature of the earthquake, no tsunami materialized.<ref>{{Cite web |last1=Lin |first1=Rong-Gong, II |last2=Wiley |first2=Hannah |last3=Garrison |first3=Jessica |last4=Solis |first4=Nathan |last5=Vives |first5=Ruben |date=2024-12-05 |title=7.0 earthquake rattles Northern California, spurs anxiety before tsunami warning is canceled |url=https://www.latimes.com/california/story/2024-12-05/earthquake-northern-california |access-date=2024-12-06 |website=Los Angeles Times |language=en-US}}</ref>
