Possible link found between earthquakes along the Cascadia and San Andreas faults

Seismic activity on the southern Cascadia Subduction fault may have triggered major earthquakes along the northern San Andreas Fault, according to new research published by the Bulletin of Seismological Society of America. The research refines the recurrence rate for the southern portion of the Cascadia fault to approximately every 220 years for the last 3000 years.
