Some EQ data I put together a while back but for the new people who likely didn't see it.

This is the months when larger quakes happen - 8.0 and up. The summer months are on the low end, while spring and fall are the highest.

OCT = 4
JAN = 5
FEB = 6
JUN = 6
JUL = 6
AUG = 7
MAR = 9 // 9.0 & 9.3 Japan & Alaska
APR = 9
DEC = 9 // 9.1 Sumatra
NOV = 10
SEP = 11

MAY = 13 // 9.6 Chile

SPRING - MAR APR MAY = 9+9+13 = 31
FALL - SEP OCT NOV = 11+4+10 = 25
WINTER - DEC JAN FEB = 9+5+6 = 20
SUMMER - JUN JULY AUG = 6+6+7 = 19
