These “Clockwork” Earthquakes Puzzled Scientists for Decades — New Indiana University Study Explains Why

Deep beneath the eastern Pacific Ocean about 1,000 miles off the coast of Ecuador, a fault line on the seafloor has been generating magnitude 6 earthquakes with almost clocklike regularity for at least three decades. The earthquakes strike every five to six years, in nearly the same places, at nearly the same size.
