Key Details Regarding 1906 and the Salton Region:
Triggered Activity: The massive, 42-second shake of the main 1906 quake triggered separate seismic events in Southern California, specifically affecting areas near the Salton Sea.
Context of the Area: At the time of the 1906 quake, the Salton Sea was just forming, having been created in 1905 by a failure in an irrigation berm on the Colorado River.
Rupture Length: The 1906 earthquake ruptured nearly 300 miles, but this rupture did not reach the southernmost portion of the San Andreas Fault near the Salton Sea.
Regional Seismicity: Studies indicate that the 1906 event did cause triggered slip in the Salton Trough. [1, 2, 3, 4]
