• Description:
  Phase alignment (synchronization) is a generalized property of interacting oscillators. If such interactions apply to earthquakes, they should manifest as time ‐dependent variations in earthquake productivity organized according to a characteristic elastic loading period. De fining this period as renewal interval, the time required to accumulate the elastic potential energy released in a rupture, gives a consistent scaling property that can be used to search for temporal organization. We test for the expected structure in earthquake productivity using three different statistical tools optimized for differenttemporal sensitivities: Schuster spectra for events with short renewal intervals (0 –25 years), Fourier power spectra for events with short and intermediate renewal intervals (0 –100 years), and topological data
