XCORLOC

XCORLOC EARTHQUAKE LOCATION PACKAGE 

XCORLOC is a Fortran computer program package for relocating earthquakes using compressional and/or shear-wave seismic data. The program can perform phase arrival (e.g., single event, static-station term, and source-specific station term) and waveform cross-correlation relocation sequentially or separately.

Bug reports, questions, enhancements, etc.

The program has been tested on both MAC and LINUX systems, but is made available without warranty.  Users of the program are free to make modifications to the programs to meet their particular needs. Tell me about your improvements and bug fixes, and we will add them to the code for everyone's benefit.

(1) topography file format (2019/4/5)

nxtopo,nytopo - number of data points along longitude, number of data points along latitude

xntopo(ix) - longitudes of data points, ix varies from 1 to nxtopo

yntopo(iy) - latitudes of data points, iy varies from 1 to nytopo

topo(ix,iy) - topography data at a given (longitude, latitude) point, in meters. Above sea level is positive.
