Query: The time distribution of aftershock magnitudes, fault geometry and
  aftershock prediction   We have analyzed, for the first time, the time cumulant of magnitudes of an
aftershock sequence since the mainshock. This comes out to be a remarkable
straight line whose slope is characteristic of the fault zone. This will
provide an useful tool in understanding the temporal distribution of
aftershocks after a specific mainshock.
