Software hypoDD to compute double-difference hypocenter locations
hypoDD is a Fortran program that implements the double-difference earthquake location algorithm of Waldhauser & Ellsworth (2000). The program package includes source codes, user guide, and several example data sets and is freely available from this site and via anonymous ftp. The file below, BugList_1.1, lists errors found in the current version (hypoDD_1.1) and tells you how to fix them. Thanks to those who pointed them out.
