- Abstract
- Hypoinverse is a computer program that processes files of seismic station data for an earthquake (like p wave arrival times and seismogram amplitudes and durations) into earthquake locations and magnitudes. It is one of a long line of similar USGS programs including HYPOLAYR, and HYPOELLIPSE. If you are new to Hypoinverse, you may want to start by glancing at the section SOME SIMPLE COMMAND SEQUENCES to get a feel of some simpler sessions. This document is essentially an advanced user's guide, and reading it sequentially will probably plow the reader into more detail than he/she needs. Every user must have a crust model, station list and phase data input files, and glancing at these sections is a good place to begin. The program has many options because it has grown over the years to meet the needs of one the largest seismic networks in the world, but small networks with just a few stations do use the program and can ignore most of the options and commands.
