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

Interoperability

systems (more formats with plugins):

Inventory


http://www.gempa.de

. . . . . .

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.


http://www.gempa.de

. . . . . .

A tree in time

The inventory is defined as a tree.

Each network, station, sensor location and stream is only defined within an

epoch.


http://www.gempa.de

. . . . . .

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.

Architecture


http://www.gempa.de

. . . . . .

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

Pipe

SeedLink collects waveform data from stations

through plugins either realtime, dial-up or

offline. Plugins for a wide range of digitizers

are available. SeedLink is a TCP/IP server and

distributes Mini-SEED streams to clients on

port 18000 (configurable).

slarchive stores waveforms in a Mini-SEED SDS

archive.

ArcLink distributes archived data to remote

clients on port 18001 (configurable).


http://www.gempa.de

. . . . . .

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.


http://www.gempa.de

. . . . . .

Processing & Analysis System

Automatic and interactive system each running on dedicated machines. Both

systems are connected to the same messaging server and acquistion system.

Explicit support

� Amplitude calculations

I Data are integrated once to velocity and processed as usual

→ no explicit strong motion amplitudes/magnitudes yet

� Waveform parametrization

I Prefers broadband data over strong motion unless it is clipped

Screenshots

The following screenshots were made with a test system running playbacks

of event data provided by SED. They show neither the correct origin time

nor the official solution issued by the SED!

Playbacks were done with only accelerometric data for demonstrational

purposes without special configuration. Only the picker was tuned for local

earthquakes and usage of full responses was enabled4.

SDK

� SeisComP3 can be extended with plugins and with new modules

� It comes with an SDK (Software Development Kit) which gives access to

waveforms, the database and the messaging system in a unified way

� Plugins can add support for new database backends, new acquisition

systems, new picker-, magnitude- or location methods, data exporter, data

importer and more

� C++ and Python are the programming languages that are supported by the

SDK which allows integration with e.g. ObsPy5

� With realtime data transmission there are no unecessary site visits to collect

data and check state of health

� All monitoring and data processing can be automated

� Spend more time on studies instead of maintenance

� SeisComP3 is free of charge for non commercial usage

Realtime data allows for maximum usage of data

� Failures are rapidly identified and fixed before the earthquake occurs

� Stations can be improved as noise is known

� Data can be continuously archived and used for locating earthquakes even if

trigger levels have not reached

� Allows implementing realtime data products such as ShakeMaps and source

inversion
