The “big one” might not come alone: Two major West Coast faults may strike back to back
New research suggests that earthquakes on the Cascadia subduction zone and northern San Andreas fault might occur in rapid succession, potentially affecting multiple major West Coast cities simultaneously. Analysis of 3,100 years of ocean sediments indicates past instances where quakes on these systems happened just minutes to hours apart, including around the significant 1700 Cascadia earthquake. }
