EF-PSHA - Probabilistic Seismic Hazard Analysis

Host Institution:

Eidgenössische Technische Hochschule Zürich  (ETHZ), Switzerland


The European Facilities for Earthquake Hazard and Risk (EFEHR) infrastructure provides access to seismic hazard and risk data and products. EFEHR WaaS (Workflow-as-a-Service) infrastructure extends to transnational access and the e-infrastructure and the physical infrastructure needed to run hazard and risk computations, perform sensitivity and uncertainty quantifications, and to make comparisons with physics-based PSHA models or alternative models.

EFEHR relies on sophisticated and computationally demanding workflows using a range of quality-controlled data products combined into a PSHA-input model and using an extensive logic tree for uncertainty representation. EFEHR includes access to computational servers and Global Earthquake Model’s OpenQuake (OQ) open-source engine for hazard and risk integration. It can deliver time-dependent and time-independent hazard curves, seismic hazard maps, uniform hazard spectra, and derived products (e.g., disaggregation). Input computational files and results for the following models:

GEM's OpenQuake open-source software for seismic hazard and risk calculation (https://github.com/gem/oq-engine)

This TA will offer both remote and physical access for training and subsequent development of research projects.

Target community/Users:
