SeisComP3Software for seismological analysis in real-time

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)

www.seiscomp3.org

SeisComP3Software 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++

SeisComP3Some 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.)
