Description

Use Rake Angle to determine style of faulting

Usage

foc.icolor(rake)

Arguments

rake	degrees, rake angle of fault plane

Details

The styles are determined by the rake angle

strikeslip abs(rake) <= 15.0 or abs((180.0 - abs(rake))) <= 15.0

rev-obl strk-slp (rake >= 15.0 and rake < 45) or (rake >= 135 and rake < 165)

oblique reverse (rake >= 45.0 and rake < 75) or (rake >= 105 and rake < 135)

reverse rake >= 75.0 and rake < 105.0

norm-oblq strkslp (rake < -15.0 and rake >= -45) or (rake < -135 and rake >= -165)

oblq norm (rake < -45.0 and rake >= -75) or (rake < -105 and rake >= -135)

normal rake < -75.0 and rake >= -105

Value

index (1-6)
