New research shows lack of seismic activity in the southern San Andreas fault in California may be due to the drying of the nearby Salton Sea and provides clues on future potential earthquake triggers, including projects aimed to refill the body of water.
The southern San Andreas fault in California is in a seismic drought, going more than 300 years without an earthquake.shows the lack of seismic activity may be due to the drying of the nearby Salton Sea and provides clues on future potential earthquake triggers, including projects aimed to refill the body of water.One of the largest faults in the world, the 800-mile-long San Andreas marks the meeting of the North American and Pacific plates in western California.
Earthquakes generally form when two tectonic plates are essentially stuck at their edges because of friction, “If previous earthquakes on it occurred every 180 years, plus or minus forty years, why is it that we sit on 300 years without an earthquake?Understanding the history of this fault and what may have caused ruptures in the past helps us inform our understanding of what might happen in the future.”The team created a computer model that simulated how a full lake affected the fault. They found high water levels in Lake Cahuilla prompted activity along the fault in two aspects.
“The correlation between the stressing rate from lake loading … and the observed earthquake likelihood is astounding,” Götz Bokelmann, a geophysicist at the University of Vienna and who was not involved in the study, said in an email. “If this holds up, then this will be quite important.”
