How do nearby earthquakes affect Yosemite?

 

 

"At half-past two o'clock of a moonlit morning in March, I was awakened by a tremendous earthquake, and though I had never before enjoyed a storm of this sort, the strange thrilling motion could not be mistaken, and I ran out of my cabin, both glad and frightened, shouting, 'A noble earthquake! A noble earthquake!' feeling sure I was going to learn something"--John Muir, The Yosemite

California is earthquake country. Most of these earthquakes occur west of here, across the Great Valley along the San Andreas Fault, but some large earthquakes have been closer:

  • 1980 magnitude 6 earthquakes near Mammoth Lakes
  • 1872 magnitude 7.4 Owens Valley earthquake

Such events are felt in Yosemite, but do they change it?
