Accelerometric Station Book

Stephanie Godey (EMSC)

Reinoud Sleeman (KNMI/ORFEUS)

NERA NA3 team: EMSC, KNMI, ETH, INGV, CNRS, METU

Set up a unique and reliable international registry of strong motion stations

ORFEUS coordination workshop, Nov 2012, Istanbul


Create an accelerometric station repository

Long term archive (international standards)

Up-to-date, accessible station information

International reference registry

Increase use and processing of station recordings by the scientists and engineers community

Ensure the sustainability of the data

Goal

ORFEUS coordination workshop, Nov 2012, Istanbul


Accelerometric station inventory na3 approach
Accelerometric Station Inventory – NA3 approach

  • Up-to-date station information crucial and common both for RRSM and ESM

  • Create a living, on-line and up-to-date inventory of all strong motion instruments in the greater European region

  • Development, initial population, hosting and technical maintenance (of the registry database) will be done by EMSC, ODC, NERA NA3 partners and the various network operators responsible for ensuring up-to-date station information.

  • Inventory will be accessible using a web browser and can (partly) be updated by network operators

ORFEUS coordination workshop, Nov 2012, Istanbul


Why is metadata important
Why is metadata important?

They are the Rosetta Stone - making it possible to decode

information well into the future.

Increases accessibility: “tell me where sites are in a

region”, or “which deployments were recording in a specific

time frame”, or “what instruments operate in this region”, etc.

Carefully created, they create both short and long-term benefits

by capturing “tribal knowledge” when it’s still available, like equipment

(serial numbers), sample rates, gains, documenting an accurate history

of ground motion. Remember: people forget !

Carefully created metadata makes your waveform data valuable !

Data preservation is important

EOS

Policy

Statement

Earth and Space data are a world heritage. Properly documented and archived, they will help future scientists understand the system……..and taking proper care of such data is our responsibility and our obligation (for future generations) …….

Current global registries
Current global registries

International registry of network codes

Federation of Digital Seismograph Networks (FDSN)

Unique network codes (max 2 characters; SEED)

Broadband community

www.fdsn.org

International registry (IR) of station codes

Maintained by ISC / NEIC

Unique station codes (max 5 characters; SEED)

www.isc.ac.uk

ORFEUS coordination workshop, Nov 2012, Istanbul


Recent initiative orfeus wg 1
Recent initiative: ORFEUS WG-1

  • FDSN and IR do not include instrument type or response information

  • ORFEUS WG-1: Broad band metadata database (Josep Vila; GFU )

Initial population of database from dataless SEED (metadata)

ORFEUS coordination workshop, Nov 2012, Istanbul


Recent initiative orfeus wg 11
Recent initiative: ORFEUS WG-1

  • FDSN and IR do not include instrument type or response information

  • ORFEUS WG-1: Broad band metadata database (Josep Vila; GFU )

  • Some remarks:

Initial population of database from dataless SEED (metadata)

Currently populated with BB stations (potentially in Europe about 1500 EIDA stations)

Network operator is responsible for correct, complete and up-to-date metadata information ( not experienced how easy this is to do)

DB populated with dataless SEED; additional fields to be filled in by operator - could serve as prototype for NA3 stationbook

Independent verification of metadata remains needed by (sophisticated) software

FSDN proposal for StationXML (most likely to be accepted in 2 weeks)

ORFEUS coordination workshop, Nov 2012, Istanbul


Additional (non-SEED) information interactively inserted by network operator

ORFEUS coordination workshop, Nov 2012, Istanbul


… but more than 3000 stations (est. 2008) stations

during the NERIES project serving

different needs and different

communities (public, seismologists,

engineers…)

ORFEUS coordination workshop, Nov 2012, Istanbul


Which metadata

Characterizing accelerometric station requires: network operator

Usual information, similar to a seismic station

Location

Response (history)

Sample rate

:

Site characterization

Geophysical description of the site

Geophysical site analysis type (borehole, noise array, H/V, etc)

Output of the site analysis (dispersion curves, traveltime

velocity, vs30)

Station characterization

Morphology

Ownership

Photos …

Which metadata?

Standard formats:

- SEED (dataless)

- FDSN Station XML (in review)

Additional information for SM stations:

No standard formats !

Nera na3 initiatives

Set up a unique and reliable international registry of accelerometric stations

Merging earthquake monitoring metadata and earthquake engineering information

Instrumental metadata via ‘authorized’ datacenters (EIDA)

View and update interface for network operators (station and site characterization)

Open user access

NERA NA3 initiatives

ORFEUS coordination workshop, Nov 2012, Istanbul


Behind the scene
Behind the scene accelerometric stations

  • Collaboration ODC+EMSC

  • Automatic update of EIDA real time accelerometric station

  • information through SeisComp3 database

  • Manual update via web interface for other information and non

  • real time stations

ORFEUS coordination workshop, Nov 2012, Istanbul


Viewing interface
Viewing interface accelerometric stations

  • Work in collaboration with Orfeus WP1 on broad band stations

  • Several national example to follow

Geoscope view interface

ORFEUS coordination workshop, Nov 2012, Istanbul


Update interface
Update interface accelerometric stations

  • Limited to network operators

  • Content responsibility to the operators

Itaca update interface

ORFEUS coordination workshop, Nov 2012, Istanbul


Operators
Operators accelerometric stations

  • What does it bring you?

  • Store your station information in a single repository

  • Enter international collaboration and data exchange

  • Maintain accurate information alive for the scientific community

  • Requirements

  • Register your network to FDSN

  • Preferably register your stations to the ISSR

  • Instrument response information

ORFEUS coordination workshop, Nov 2012, Istanbul


Developments
Developments accelerometric stations

  • 1,000 stations from NERA NA3 participants will be inserted in the database

  • Collaborations with USGS for common initiatives

  • Collaborations with working groups on site characterization (NERA JRA1)

  • Collaborations with other ongoing projects: Sigma

  • We need your feedback and your approval !

Station Book @ EMSC

(based on RRSM DB)

required:

- FDSN network code

- ISC station code

● SB stations without SEED metadata will not be populated into the RRSM DB @ ODC

● Raw and processed event waveform data stored @ ODC; continuouus waveforms deleted after 6 months

ORFEUS coordination workshop, Nov 2012, Istanbul


  • metadata must be shared in standard format (dataless SEED, FDSN

  • StationXML) which makes metadata “portable” amongs

  • heterogeneous systems

  • Whenever anything changes at a site, new metadata should

  • be exchanged with archives and/or other networks using it.

ORFEUS coordination workshop, Nov 2012, Istanbul
