Figure 1. Maps of earthquake rate change following the Landers earthquake (a) and the
Hector Mine earthquake (b). The quantity that is mapped is
N
in equation
(1) that is calculated for
nonoverlapping spatial windows with dimensions of 0.5 x 0.5 deg. The time
windows are tpost = 10 days,
tpre = 100 days, and
tlt is between January 1985 and January 2002. The
stars indicate the epicenters of the Landers and the Hector Mine earthquakes.
Aftershock activities are examined in four regions that are indicated by solid
rectangles and are labeled as North1, North2, LVC, and South.
