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. Defining 
 this period as renewal interval\, the time required to accumulate the elas
 tic potential energy released in a rupture\, gives a consistent scaling pr
 operty that can be used to search for temporal organization. We test for t
 he expected structure in earthquake productivity using different statistic
 al tools optimized for different  sensitivities.  These tests show structu
 re in the arrangement of earthquakes in time that could be used to improve
  forecasting skill and advance our understanding of global earthquake inte
 ractions.  \n\nBackground reading:\n\nBendick\, R. and Mencin\, D. (2020)\
