[S01-1-03] Over 20 years of HYPOSAT: Newest developments

Johannes Schweitzer (NORSAR / Univesity of Oslo, Norway)

About 20 years ago, the first versions of HYPOSAT, a free software package to locate seismic events at local, regional and teleseismic distances were developed and presented (Schweitzer, 1997). In 2001, a paper was published describing the principal features of the program package and the software package was officially released (Schweitzer, 2001). Later, a detailed manual became part of the IASPEI New Manual of Seismological Observatory Practice (Schweitzer, 2002).
During the last decade, many new features steering the inversion process and correcting for effects that can influence seismic travel times were implemented in HYPOSAT and many options to handle input and output data were included. Today's program version can run on Unix and Linux platforms.
The program package has been used by many researchers worldwide. These users have helped to improve the software by reporting problematic results and bugs and requested additional input / output options.
In this talk an overview will be presented over the principal ideas behind HYPOSAT. Additionally, many of the recently implemented features will be explained and discussed.
