SEISANEarthquake Analysis Software
Lars Ottemöller and Jens Havskov (University of Bergen)
Peter Voss (GEUS)
Background
• Development started in the late 80s• Large number of software contributors• Steady improvements, now Version
9.1• Basics unchanged• Supported operating systems: Solaris,
Windows, Linux and MacOS
Who uses SEISAN
• Geographically widely used(Norway, UK, France, Spain, ..., India, Iran, Philippines, ..., Central and South America, South and East Africa, ...)
• 15% of data sent to ISC in SEISAN format
• National and regional seismic networks• Volcano observatories• Researchers
What can you do with SEISAN
• Import/Export data• Store data (waveform and parametric)• Observatory routine:
– Analyse earthquake data (signal processing, phase identification, ...)
– Compute earthquake parameters (location, magnitude, ...)
– Fault plane solution– Seismicity maps– Produce bulletin and catalogue search
• Research platform, several additional data processing tools
Philosophy• Open source• Open system• Non-commercial• Multi-platform • Integrate essential tools and data
storage into one package• Provide documentation• Provide support• Provide training
SEISAN Help
• Manual (PDF and HTML)• Training document• Seisan Webpage
http://www.uib.no/rg/geodyn/artikler/2010/02/software
• Mailing list: [email protected]
• Authors: [email protected]@[email protected]
Other software
• SAC(http://www.iris.edu/manuals/sac/index.htm)
• Geotool (CTBTO)• Seismic Handler
(http://www.szgrf.bgr.de/sh-doc/index.html)• Giant/Pitsa
(http://www.geo.uni-potsdam.de/forschung/software/giant.html)
• …• Link on Orefus and IRIS
Data Types
•Waveform data•Calibration data•Parametric data
Waveform data
• Created by digitising analogue output from seismometer and time stamping
• Consists of amplitude and time• Translates into ground motion using
instrument response information• Written out by data acquisition
system• Waveform formats understood
directly by SEISAN: SEISAN, SEED, miniSEED, SAC, GSE
Waveform data files
• Single or multiple channels• Data identifier: Station code, Channel
code, Network code, Location code• Timing information• Data values
• Used for: Recording, analysis, archival, data exchange, …
Waveform data into SEISAN
• Conversion of data created by data logger
• Conversion of data provided by another agency (IRIS, ORFEUS, ...)
• Data written out by near real-time processing system (Earthworm, Seislog, SeisComP, ...)
• Automated data collection: SEISNET
Waveform ConversionExamples
• Rdseed: SEED -> miniSEEDSEED -> SAC…
• Wavetool: (mini)SEED <-> SEISAN
SAC <-> SEISANGSE <-> SEISAN
• …
Parametric data
• Derived from waveform data• Observations:
– Arrival times and residuals– Amplitudes– Polarities
• Computed:– Hypocenter location– Magnitudes– Fault plane solution
