EnglishIs the SHARE Project Still Active or Updated?
Updated
No. SHARE (Seismic Hazard Harmonization in Europe) ended in 2013. The project was a Collaborative Project under the European Commission's Seventh Framework Programme, and its site describes the status plainly as "Ended in 2013." The website remains as an archive of the project's outputs — most importantly the 2013 Euro-Mediterranean Seismic Hazard Model (ESHM13) — but it is not an ongoing program with new project activity.
What SHARE was
SHARE's objective was to produce a community-based seismic hazard model for the Euro-Mediterranean region, with update mechanisms built into the design. It aimed to set new standards in Probabilistic Seismic Hazard Assessment (PSHA) by bringing together leading European geologists, seismologists, and engineers.
The project:
- Built a framework for integration across national borders
- Compiled relevant earthquake and fault data
- Developed a hazard model through extensive expert elicitation and multiple community feedback procedures
What it delivered: ESHM13
The main product is the 2013 Euro-Mediterranean Seismic Hazard Model (ESHM13). Key characteristics from the project's own description:
| Feature | Detail |
|---|---|
| Output | More than sixty time-independent ground motion hazard maps |
| Spectral ordinates | PGA to 4 seconds |
| Exceedance probabilities | 10⁻¹ to 10⁻⁴ yearly probability |
| Reference rock velocity | vs30 = 800 m/s |
| Source types | Area sources, active faults, smoothed background seismicity |
| Magnitude threshold | All events with Mw ≥ 4.5 included in hazard computation |
| Weighting | Innovative scheme weighting input datasets by time horizon — emphasizing geologic knowledge for longer time horizons and seismological data for shorter ones |
What "ended" means for users
If you are looking for current hazard data or an actively maintained model, SHARE itself is not the source. The project's own framing is historical: it delivered ESHM13 and a framework, and the outreach materials (official poster, brochures) are hosted at efehr.org rather than maintained as a live service on share-eu.org.
Practical implications:
- For the model and results — cite and use ESHM13 as a 2013 product, not as a continuously updated dataset.
- For documentation — the site's Documents and About sections, plus the EFEHR documentation pages, are the available references.
- For updates — the project description mentions "update mechanisms" as an objective, but the stated project status is ended, so no ongoing update activity should be assumed from this site.
How to cite it
The project lists specific citations:
- SHARE Project: Giardini, D., Woessner J., Danciu L. (2014) Mapping Europe's Seismic Hazard. EOS, 95(29): 261–262.
- ESHM13 models and results: Woessner, J., Danciu L., D. Giardini and the SHARE consortium (2015), The 2013 European Seismic Hazard Model: key components and results, Bull. Earthq. Eng., doi:10.1007/s10518-015-9795-1.
Bottom line
SHARE is a completed project, not an active one. Its value today is as the source of ESHM13 and its documentation. If your task requires a currently maintained European seismic hazard model, treat SHARE's outputs as a historical baseline and look to whatever successor or host service the documentation points to, rather than expecting updates from share-eu.org itself.
