2. Software for seismological analysis in real-time
SeisComP3
Software for seismological analysis in real-time
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

3. Software for seismological analysis in real-time
SeisComP3
Software 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

4. SeisComP3 Features 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

6. SeisComP3 Recent achievements 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.)
.....

7. Originally developed for teleseismic (tsunamigenic) earthquakes – flexibility for monitoring local earthquakes

9. 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

29. Interactive Analysis Advantages of automatic processing:
updates are send continuously while processing
faster in case of a dense network
Disadvantage:
solutions are not reviewed
=> Quality through Quantity
Advantages of manual processing:
faster at the beginning especially in case of a less dense network
solutions are reviewed
updates only in case of new analysis
slower in case of a dense network
=> Quality depending on qualification of the seismologist

32. Future of SeisComP3
GITEWS project, by which the development of SC3 was
financed, ended in March 2010
Gempa is a spin-off from GFZ and is providing long term
support for SC3
Business model is based on:
Support & Maintainance
Training
Software development
