Abstract: Seisan is a software package for the routine processing of 
earthquake data. The development of the software was started by JH in 
the late 80s due to the need for a processing tool of the new digital 
seismic network in Norway. The software was designed to be also useful 
for others and soon developed into a toolbox that was used at a number 
of mostly local seismic observatories. Today, Seisan is very widely used 
around the world mostly at local seismic networks, volcanic 
observatories and by individual researchers. It provides all essential 
tools needed for the basic processing of earthquake data to obtain the 
location, magnitude, source parameters and fault plane solution. In 
addition it has a number of programs for basic research and export 
support for some standard research software. Data are stored in a simple 
directory based database system, which has allowed for consistent 
long-term storage of waveform and parametric data. Seisan is very open 
in the sense that it can work with data from a wide variety of 
acquisition and processing systems. Seisan can for example read 
continuous data from a seiscomp or bud archive system. One can also use 
Seisan on data and response files extracted from a SEED volume. It is 
also rather simple to extract data from Seisan for processing in another 
system or for usage in research. Seisan works on the standard operating 
systems Microsoft Windows, Linux, Solaris and MacOS. It is distributed 
with the entire source code, a manual and training material. Seisan may 
not have the bells and whistles of some more modern systems, but due to 
its efficient ways in the processing presents an attractive and robust 
solution for many.
