Where to Access SHARE Project Data and Documentation

Updated

SHARE (Seismic Hazard Harmonization in Europe) was an EU Seventh Framework Programme project that ended in 2013, and its data and documentation remain accessible through two main routes: the SHARE Portal's "Data Access" section on share-eu.org, and the outreach materials hosted at efehr.org. If you need the underlying hazard model, maps, or citation details for the 2013 Euro-Mediterranean Seismic Hazard Model (ESHM13), both entry points are still usable even though the project itself is closed.

Accessing Data Through the SHARE Portal

The share-eu.org site is organized around a menu that includes Home, SHARE Portal: Data Access, About SHARE, Work Packages, Documents, Related Projects, Partner Area, EC Resources, and Contact.

  • SHARE Portal: Data Access is the primary entry point for the project's data products.
  • Documents and Work Packages sections hold project documentation and descriptions of the work carried out.
  • Related Projects links to connected initiatives, useful if you need broader context or successor work.

The portal is the natural starting point if you want the model outputs directly rather than summaries.

What the Data Contains (ESHM13)

The main deliverable was the 2013 Euro-Mediterranean Seismic Hazard Model (ESHM13). Key characteristics:

Feature Detail
Output More than 60 time-independent ground motion hazard maps
Spectral ordinates PGA up to 4 seconds
Exceedance probabilities 10⁻¹ to 10⁻⁴ yearly probability
Reference rock velocity vs30 = 800 m/s
Earthquake modelling Area sources, active faults, smoothed background seismicity
Magnitude inclusion All events with Mw ≥ 4.5
Weighting scheme Reflects input data importance by time horizon — geologic knowledge weighted for longer horizons, seismological data for shorter ones

This matters if you are comparing ESHM13 against later models or need to know whether a given map suits a long-horizon (geology-driven) or short-horizon (seismology-driven) use case.

Outreach Materials and Official Documentation

The project's outreach materials — the official poster and brochures — are available at:

www.efehr.org/en/Documentation/specific-hazard-models/europe/overview/

Use this if you want presentation-ready summaries rather than raw model files. The EFEHR (European Facilities for Earthquake Hazard and Risk) site is the more stable long-term host, since SHARE itself concluded in 2013.

Citing SHARE and ESHM13

If you use the data in publications, the site 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.
  • Data and illustration: additional citation details are listed on the site.

Practical Notes

  • The project ended in 2013, so treat all content as a fixed historical release rather than a live, updated dataset.
  • The site does not indicate pricing or login requirements for these resources; check the Data Access page directly to confirm what is openly available versus restricted.
  • For current or updated hazard models, the EFEHR link is the better long-term reference point, since it continues to host SHARE-derived materials.
