Although it’s possible for a very large quake on one fault to send tremors along the span of another fault, faults usually break in segments, so it would normally take very potent quakes to do that.
Though it hasn’t ruptured in recorded time, Donnellan said the Elsinore fault, which links up with other potentially devastating faults, is capable of “producing very big quakes.”
