8 Evolution 2006 Development of the 3 rd generation (SeisComP3 ) within the GITEWS 2 project 2007 Installation at BMKG, Jakarta/Indonesia in May First public release of SeisComP3 in Barcelona/Spain 2009 Release of SeisComP3 Erice in Erice/Italy Improved event parameters schema 2010 Release of SeisComP3 Potsdam in Potsdam/Germany Improved inventory schema 2011 Release of SeisComP3 Zürich in Potsdam/Germany Tailored towards local network monitoring with funding by the SED/ETH 2012 Release of SeisComP3 Seattle in Potsdam/Germany Redesigned configuration framework with funding by IRIS 2 Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

9 Components Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

10 SeedLink Realtime and dialup data acquisition server Implements the SeedLink protocol which is a de facto standard for seismic data distribution Uses Mini-SEED format, the realtime version of SEED, which is the standard format for seismic data exchange. Data are converted to Mini-SEED (and thus homogenized) as early as possible. Supports a wide range of digitizers and protocols such as Quanterra, Guralp, Reftek, Nanometrics, Earthworm, WIN, LISS,... Data access control on station level to distinguish between free and restricted data Well supported by other packages such as Earthworm and SeisGram Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

11 ArcLink Archived waveform and metadata (station information) distribution server Complements SeedLink by providing a longer store of data Implements the ArcLink protocol also used within the EIDA (European Integrated Data Archives) project Distributes waveform data of an SDS archive Distributes metadata in XML or dataless SEED Comes with a web interface similar to.. to allow data requests in a user friendly way Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

12 Processing Distributed processing within a TCP/IP network Independent modules synchronise with a messaging system QuakeML 3 derivative as database schema and communication protocol Automatic phase picker, locator and event associator Built-in magnitudes: MLv, ML, mb, mb, mbc, Mwp Continuous quality parameters for quality control PGA/PGV/response spetra computation e.g. to generate ShakeMaps Database support for MYSQL, PostgreSQL and SQLite3 (others through plugins) Results are stored and distributed as soon as they are availabe 3 Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

13 Analysis Graphical user interfaces to the system to configure and manage it check data quality visualize events analyse waveforms and pick onsets show waveforms in a realtime display or as heliplots get an overview of the current situation of the network monitor state of health Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

14 Interoperability SeisComP3 supports various formats to import/export their data from/to other systems (more formats with plugins): Format Import Export Key files (inventory) X ArcLink (inventory) X X QuakeML 1.2 (event parameters) X StationXML (inventory) X X Dataless SEED (inventory) X X Mini-SEED (waveforms) X X AH (waveforms) X SAC (waveforms) X Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

15 Inventory Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

16 Schema Station metadata (inventory) is a fundamental requirement for data processing. SeisComP3 includes a generic inventory (stations + instruments) schema as a function of time. XML (import/export) and SQL (database) representations are available. Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

17 A tree in time The inventory is defined as a tree. Each network, station, sensor location and stream has associated start and end times Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

18 Example layout A network is a group of stations. A station defines several sensor locations each having a coordinate (latitude, longitude). A sensor location defines several streams which describes the output of the sensor-datalogger combination. Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

19 Architecture Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

20 Architecture Retrieves waveform data from remote stations, archives it and distributes it to clients on request Modules: SeedLink, slarchive and ArcLink Processes waveform data automatically and emits derived parameters such as picks, amplitudes, magnitudes, hypocenters and events Modules: scmaster, scautoloc, scautopick, scamp, scmag and scevent Provides graphical user interfaces to analyse and verify results and waveforms interactively either in realtime or as post event analysis Modules: scrttv, scmv, scolv and scesv Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

21 Architecture Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

22 Acquisition System SeedLink collects waveform data from stations through plugins either realtime, dial-up or offline. Plugins for a wide range of digitizers chain SeedLink2SeedLink Pipe Port: slarchive Scream! SeedLink... wf <SDS> are available. SeedLink is a TCP/IP server and distributes Mini-SEED streams to clients on port (configurable). slarchive stores waveforms in a Mini-SEED SDS archive. ArcLink distributes archived data to remote clients on port (configurable). Port: ArcLink Acquisition Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

23 Processing System Acquisition system provides realtime data and archived data scmaster as messaging server manages metadata (picks, amplitudes,...) exchange between SC3 modules and populates the database. scevent associates origins (locations) with events and chooses the best location and magnitude among all candidates based on configurable rules. Jan Becker (gempa GmbH) SeisComP3 Introduction March 11, / 43

24 Processing & Analysis System Automatic and interactive system each running on dedicated machines. Both systems are connected to the same messaging server and acquistion system.. Jan Becker (gempa GmbH) SeisComP3 Introduction.... March 11, / 43
