Software package for seismological data acquisition, quality control,
archiving and automated/manual analysis in real-time
SeisComP3 originally developed within the GITEWS project
(NOT available for MS Windows)

2. 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
Uses/supports standards: SEED, SeedLink, QuakeML based data model used
for storage and communication, ArcLink
GUI‘s for quick manual interaction/review, waveform visualization, event
visualization and state-of-health monitoring
Framework for seismological software development
Inter-process communication between modules using TCP-based
messaging to allow distributed processing; communications managed
by central mediator; C++

3. SeisComP3 Some Features Automatic P picker (STA/LTA; AR-AIC)
Automatic global phase associator/locator (LocSAT); grid search
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

4. SeisComP3 Some Features
Station inventory XML schema (dataless SEED import)
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 of locator and traveltime tables
Offline mode to work with mseed or XML files; replay
Automated moment tensor (Hamburg Univ.)

10. Metadata is required for stations to be processed by SeisComp
(1) create key-files
import_dlsv -p “acquisition:iris” dataless_II.SSS1
import_dlsv -p “acquisition:iris” dataless_IU.SSS2
import_dlsv -p “acquisition:stat3” dataless_NN.SSS3
import_dlsv -p “acquisition:stat4” dataless_NN.SSS4
profile in ~/seiscomp3/acquisition/key/profile_iris
SRCADDR=‘rtserve.iris.washington.edu’
SRCPORT=‘18000’
(2) sesicomp config and choose option ‘W’
(3) sync_dlsv dataless_NN.SSS (updates the DB)

~ 1000 stations, ~100 TB

26. 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
