HYPOSAT 6.2 and HYPOMOD 2.2 – The User Manual

HYPOSAT is a program developed to locate single seismic sources and HYPOMOD is a program to calculate residuals of observed data for a given seismic source location. Both programs utilize observed onset time, backazimuth (i.e., station-to-event azimuth, BAZ) and ray-parameter observations. Additionally, all possible travel-time differences between different onsets at individual stations can be included in the location process (e.g., the onset-time difference between the phases PcP and P (tPcP – tP) gives additional constraint for the source depth). If amplitude and period measurements are available for P or S onsets or for surface waves, individual station and network magnitudes can also be estimated.
