SeisComP3Software for seismological analysis in real-time
Software package for seismological data acquisition, qualitycontrol, archiving and automated/manual analysis in real-time
SeisComP3 originally developed within the GITEWS project
(NOT available for MS Windows)
• Originally designed as acquisition and archiving software for GEOFON
• SeedLink as core protocol became a de-facto standard in Europe since 2001
• Since 2003 development of simple automatic analysis tools
• Since 2005 with global associator/locator, interactive analysis (SH, SeisComP2)
• ArcLink for distributed archives (waveforms and meta data)
• Mid of 2006 start of SeisComP 3 core (communication, database) - TWS
• SeisComP 3 GUI development starting in end of 2006
• Installation at BMG (Indonesia) in May 2007
SeisComP3Software for seismological analysis in real-time
SeisComP3Software for seismological analysis in real-time• Software package for seismological data acquisition, quality control, archiving and automated/manual analysis in real time
• Inter-process communication between modules using TCP-based messaging to allow distributed processing; Communications managed by central mediator
• Uses/supports standards: SEED, SeedLink, QuakeML data model used for storage and communication
• GUI‘s for quick manual interaction/review, waveform visualization, event visualization and state-of-health monitoring
• Framework for seismological software development
SeisComP3Features• Automatic P picker (STA/LTA; AR-AIC in progress)
• Automatic global phase associator/locator (LocSAT)
• Magnitudes implemented: ML, MJ, mb, mB, Mw(mB), Mwp, Mw(Mwp) Slower magnitudes have no high priority, but will be implemented (e.g. Ms)
• Manual interaction where necessary; relocator choice (LocSAT, NonLinLoc)
• Remote processing/review
• SeisComP 3 uses (broadband!) mB as default magnitude for large earthquakes
• Written in C++ with most functionality available as library functions
• Database support as module (MySQL, SQLite, PostgreSQL)
• Scripting interface for the Python language
• Station inventory improved schema• Use of full instrument response (e.g. MT, strong motion data)• Abstract locator interface to allow use of not just LocSat• NonLinLoc fully integrated as relocator option (ETH funded)• Choice in scolv of locator and traveltime tables• scolv offline mode to work with mseed files• some new magnitudes incl. broaband Ms• automated moment tensor (Hamburg Univ.)• .....
SeisComP3Recent achievements
Originally developed for teleseismic (tsunamigenic) earthquakes – flexibility for monitoring local earthquakes
Upcoming Features
•Multiband picker•Different velocity models•QuakeLink (based on jabber protocol)•Support of MacOS•Other fast magnitudes available (Mwp) or planned (Mwpd, mBc, ...)•Oracle support planned
