inverseTAPE {RFOC}

Inverse Moment Tensor

Description

Inverse moment tensor from Tape angles.

Usage

inverseTAPE(GAMMA, BETA)

Arguments

GAMMA

Longitude, degrees

BETA

CoLatitude, degrees

Details

Uses Tape and Tape lune angles to estimate the moment tensor. This function is the inverse of the SourceType calculation. There are two solutions to the systems of equations.

Vectors are scaled by the maximum value.

Value

Moment tensor list:

Va

vector, First solution

Vb

vector, First solution

Note

The latitude is the CoLatitude.

Either vector can be used as a solution.

Orientation of moment tensor is not preserved int he lune plots.

Examples

lats = seq(from = -80, to = 80, by=10)
    lons = seq(from=-30, to=30, by=10)

i = 3
j = 3
 u =  inverseTAPE( lons[i], 90-lats[j] )
