Thanks decimon.

When its natural dimensions were in place, Lake Cahuilla and its surrounding region experienced in a 1,000-year period five earthquakes on the Southern San Andreas that are believed to have been larger than magnitude 7. The temblors occurred about 180 years apart. It's been more than 300 years since the last one... the sediments deposited over several millennia on the lake floor.. coincident... between several flooding events and rupture of step-over faults... Stress models showed that the predominantly normal faults with vertical displacement in the Salton Sea are more vulnerable to sudden increases in vertical loads caused by lake filling. Those failures may have triggered the movement of California's primary fault in several instances, the researchers said. No such sequence has taken place since the lake assumed its current dimensions.

Present day Lake Cahuilla is a man made lake, and the men who designed it joke about the shape they designed it to fit. (IMHO, with maturity levels of 3rd graders)
