Calculate passive slip and considering stress shadow

PassiveSlip

You can estimates Mechanical Coupling Distribution using MCMC, or do forward simulation by Est_PassiveSlip.m.
Usage of main script, Est_PassiveSlip

 EST_PassiveSlip('option1','option2')

'option1' is calculation method: 'fwd', forward simulation; 'mcmc', MCMC estimation
'option2' is MCMC algorithm: 'mh', Metropolis-Hasting method; 're', Replica exchange method
If you enter no option (i.e. just type EST_PassiveSlip), MCMC estimation using MH method will run.

• Required files to run

  • Block line files.
    File name requires block number, such as 01_hoge.txt, 02_fuga.txt
    File format is Lon. and Lat. in 1st and 2nd columns, respectively. Note that the block line must be closed line (i.e. first and last rows must be equal).

  • (Option) Shape or trimesh files of Block boundaries.

  • Observation data file
    File format is

    Site_ID  Lon  Lat  Hig  vE  vN  vU  sigmaE  sigmaN  sigmaU  weight
    

    Units of each value are below
    Lon, Lat: (deg)
    Hig: (m)
    vE, vN, vU, sigmaE, sigmaN, sigmaU: (mm/yr)

  • Parameter files

    • PARAMETER/Parameter.txt
      Parameters to run the script.

    • PARAMETER/opt_bound_par.txt
      Optimize the point interval of block boundary.

    • PARAMETER/interp_randwalkline.txt
      Interpolate the udline in which the up- and down-dip limit (Zu and Zd) of mechanical coupling region.
      File format is

        Lon_Zd_1 Lat_Zd_1 Zd_1 Lon_Zu_1 Lat_Zu_1 Zu_1
        Lon_Zd_2 Lat_Zd_2 Zd_2 Lon_Zu_2 Lat_Zu_2 Zu_2
