Trees as indicators of past movements on the San Andreas Fault
R. E. Wallace, Valmore C. LaMarche Jr.
1979, Earthquake Information Bulletin (USGS) (11) 127-131
Trees are sources of information about fault movements that have occurred before the earliest historical reports. This kind of evidence can be used to improve estimates of when earthquakes will recur on faults known to be seismically active and to identify active faults that have no record of movement during...
