Overview of Technical Developments for Capacity Building in Strong Motion in NERA NA3

Overview •  Political discussion crucial but not the core part of the presentations in this session

•  Present a framework for accessing strong motion data from Europe in a coordinated manner

•  2 main parts:

§  Discovery of, and access to, strong motion data as rapidly as possible after an earthquake

§  Creation of a high quality, updated, strong motion catalogue for researchers

•  Also create a on-line, interactive inventory for strong motion station in greater European region

•  All data available on a webportal

Strong motion databases in Europe FP 4

FP 5 Ambraseys et al. group

Collecting, compiling and processing of strong-motion data (uniform structure of data & metadata)

Actually maintained by the University of Iceland

FP 6 Homogeneous accelerometric database

Automatic processing

FP 7 Follow up of NERIES. Goals: dynamic database

2007-2010: Improvements of national strong-motion databases (e.g. Italy, Turkey)

Strong-motion databases (no portal, no improvement or homogenization of collected data) FP 7

Collection of European data. Data are published after the revision of metadata by a board of experts. Finalised to the evaluation of GMPE and GM variability

NERA NA3 Main Objective

Build European integrated databanks of strong-motion records and associated metadata relevant and accessible to both earthquake engineering and seismology communities that reflects the state of the art and research needs in these fields.

‘Peer-reviewed’ databanks using manual processing

Rapidly available databanks using automatic processing

RRSM ESM

EIDA (European Integrated Data Archives) Italy (INGV), France (RESIF), Germany (GFZ, BGR), Switzerland (SED), ORFEUS Centralised access to distributed waveform archives All VEBSN stations included -  All EIDA nodes run ArcLink with SeisComp3 dB

-  Data hosted at distributed node -  Metadata maintained locally by each node -  Metadata for whole system synchronised at each node

-  Discovery of entire dataset possible from each node -  Request for data made at any individual node will reroute data request to node which has the data

Rapid, Raw Strong Motion (RRSM) data (automatic, near real time, back to ~2000)

Engineering Strong Motion (ESM) data

(regular manual updates)

Generic seismic data (currently: Event / Broadband Waveform

RRSM Event / Parameter dB (SC3)

Processed ESM event waveforms

Static ESM Event / Parameter dB + waveforms

Station Book -  Online, interactive station book for all strong motion stations

-  Automatically will includes stations in EIDA / RRSM -  Other stations can be included manually through website

-  Additional metadata (eg sensor / datalogger type, vault type, free field, geology) not in EIDA dB can also be manually included

Strategy for future

-  NERA NA3 efforts will demonstrate technical feasibility for rapid and high quality data dissemination using modern tools

-  How to continue and nurture these efforts in Europe

-  EPOS: long term strategy for Earth Sciences

-  Strong motion is part of Seismological Observations section

-  Strong motion can become part of ORFEUS mandate

-  Provides a neutral coordinating body that can encourage open realtime and archive data, establish MoUs – like it has done with Seismology

-  EPOS also will secure technical continuity of RRSM / ESM

Questions to Address at this meeting.

-  How do regular strong motion networks join in these efforts?

-  Political: what setup do you want?

-  Technical:

-  joining RRSM (realtime / EIDA)?

-  Joining ESM?

-  Continue with individual dissemination tools?
