# PSGRN and PSCMP (packaged as fomosto backend)
|
||||
|
||||
Code to calculate synthetic stress/strain/tilt/gravitational fields on a
|
||||
layered viscoelastic halfspace.
|
||||
|
||||
PSGRN and PSCMP have been written by Rongjiang Wang.
|
||||
|
||||
Packaging has been done by Hannes Vasyura-Bathke.

# 1. number of subfaults (<= NSMAX in pscglob.h), latitude [deg] and east

# longitude [deg] of the regional reference point as origin of the Cartesian
|

# coordinate system: ns, lat0, lon0
|

#
|

# 2. parameters for the 1. rectangular subfault: geographic coordinates
|
||||
# (O_lat, O_lon) [deg] and O_depth [km] of the local reference point on
|
||||
# the present fault plane, length (along strike) [km] and width (along down
|
||||
# dip) [km], strike [deg], dip [deg], number of equi-size fault
|
||||
# patches along the strike (np_st) and along the dip (np_di) (total number of
|
||||
# fault patches = np_st x np_di), and the start time of the rupture; the
|
||||
# following data lines describe the slip distribution on the present sub-
|
||||
# fault:
|

#
|
||||
# pos_s[km] pos_d[km] slip_along_strike[m] slip_along_dip[m] opening[m]
|
||||
#
|
||||
# where (pos_s,pos_d) defines the position of the center of each patch in
|
||||
# the local coordinate system with the origin at the reference point:
|
||||
# pos_s = distance along the length (positive in the strike direction)
|

# pos_d = distance along the width (positive in the down-dip direction)

# faults (each causes a third part of the volume of the point inflation)

# with orientation orthogonal to each other. the results obtained should
|

# be multiplied by a scaling factor 3(1-nu)/(1+nu), where nu is the Poisson
|

# ratio at the source. The scaling factor is the ratio of the seismic

# a plate openning with the same volume change.
