GFZ (GEOFON; Potsdam) Winfried Hanka, Joachim Saul, Andres Heinloo, ... GEMPA (Potsdam) Bernd Weber, Jan Becker, ... SeisComP3 Software for seismological analysis in real-time www.seiscomp3.org 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)
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++
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
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.) SeisComP3 Some Features
