SHARE Annual Meeting 15-16 June 2010
The 1st Annual Meeting of SHARE on June 15 / 16, 2010, brought together over 60 dedicated scientists and invited experts from all over Europe. The two-day meeting was hosted by INGV in Rome and had a full agenda, yet sufficient time was reserved for discussions of particular hot-topics of the Work Packages (WP).
The meeting provided participants with an up-to-date overview of where SHARE stands after 1 year of operations, and with still 2 years to go. Of eleven deliverables scheduled for the past year, 7 were finished, there are minor delays (1-2 months) for 3 deliverables one has been postponed for 6 months. With regard to the milestones; all have been met except for the one on the complex IT-infrastructure because of an IT-review meeting that might be beneficial for SHARE development.
The management and coordination of the project (WP1) is working well. An infrastructure has been set up to support exchange of information and to support project management. This website contains all tasks and deliverables and future reports, has a workspace for each WP and indicates the progress.
WP2 is focused on defining engineering requirements and applications. In this first year a hazard output specification document was produced, which guides outputs of Work Packages 4,5 and 6, based on the specific EC8 end-user needs.
Earthquake sources and activity rates is the title of WP3, by far the largest SHARE Work Package, which prepares the basic datasets for the PSHA as main objective. Over the first 12 project months, the WP has returned important results on three main sets of input data that are essential for further developments in SHARE:
- The compilation of a new earthquake database is well underway bringing together and building on results from the EC-FP6 project NERIES and catalog work by the GeoForschungszentrum Potsdam (GFZ). The final database will be delivered in the first half of year 2.
- A new European Seismic Source Zone Model (SSZM) has been harmonized out of
national and regional programmes; special attention was given to the finer details of models across boundaries and will be delivered in the next months. - The compilation of the first pan-European database of active faults and seismogenic sources is well underway and will be delivered as well in the first half of year 2. The database will include at least 316 fully-parameterized seismogenic sources more than at the start of the project, covering over than 20.000 km more).
In addition, WP3 has supplied a simplified 3D geotectonic model suitable for defining the application regions for the ground motion prediction equations to be used in different tectonic regimes of Europe.
Work Package 4 deals with strong ground modeling. Within the first year a high-quality update of the strong-motion database was delivered bringing together data from all over the world. Furthermore the available and relevant Ground Motion Prediction Equations (GMPEs) have been selected and partly implemented in the Seismic Hazard Engine, while required adjustments were carried out.
The Seismic Hazard Assessment Work Package, WP5 is, in accordance with SHARE’s Description of Work still in a preparatory phase. A source specification document and a quality assurance report have been produced within the scope of the WP that is a step towards new standards in PSHA for future projects.
WP6 Computational Infrastructure has produced a definition of typologies and the development of a community data model (shaML). Proof-of-concept calculations with the Seismic Hazard Engine have been carried out. These do not include complex logic tree weighting and results are therefore not to be used. Requirement reports on graphical user interface design and functionality of the SHARE portal accompanied with an initial implementation during the GEM1-project are finished.
The last Work Package is on dissemination. WP7 has produced a fully functional website displaying all the relevant information on the project, highlights and news. It is based on a content management system, which includes automatic registration for the SHARE newsletter. The website is easy to maintain and adapt to changing needs as the project proceeds.
Besides a view on the current status, the various WP representatives provided the participants with an outlook of future developments. The session dedicated to single WPs proved to be essential in order to make some necessary decisions, especially in the scope of WP3. The requirements from the hazard assessment and IT-workpackage were clarified as well theas 
timeline and additional data to be provided for building the hazard model. In the end, the hazard model shall contain a traditional areal source zone model as well as models based on the combination of fault sources and smoothed seismicity approaches.
At the end of the meeting, the General Assembly discussed the general progress of the project and approved minor changes to the breakdown of work structure and the budget. All participating institutions have a vote in the assembly and as during the first assembly there seemed to be unanimous agreement of them on the project and the way forward.
Session Announcement - 33rd General Assembly of the European Seismological Commission, Moscow, Agust 2012: SHARE together with other regional programs of GEM have suggested a session "SHR-1: Recent Developments in Probabilistic Seismic Hazard and Seismik Risk Assessment: Applications, Improvements, Shortcomings and Perspectives". Looking forward to your contributions! Abstract submission deadline is March 31, 2012.
