[Withdrawn] The Sigma-2 Research Program: Improved Seismic Hazard Assessment Practices Adapted to Site Conditions

Our objective is to introduce the SIGMA-2 R&D program on seismic hazard assessment (“SeIsmic Ground Motion Assessment, 2nd edition”). Built upon SIGMA project (2011-2016) legacy, this program aims at delivering an improved representation of the seismic ground-motion, adapted to local site conditions, with a particular emphasis on low seismicity areas.

The program is funded by a consortium of industrial partners operating, managing, controlling facilities (including nuclear installations), and sharing a common interest in improving seismic hazard assessment (SHA) practices within an open collaboration framework. The program organization has been elaborated so as to strengthen the link between researchers and seismic/civil engineers, by involving international representative from private and public sectors from the realization of research actions to the Scientific Committee supervisory level. Besides, bi-annual workshops offer the opportunity to conduct extensive technical discussions/reviews with end-users and to anticipate future impacts on SHA studies.

A dedicated Scientific Committee has been constituted to monitor the quality of SIGMA-2 scientific outcomes, and to provide guidance on technical aspects. In addition, project deliverables must comply with a formal review process supervised by this Committee.

SIGMA-2 research actions are organized into 6 Work Packages with expected contributions at every step of the SHA process: Fault & tectonics; Earthquake catalogs & parameters; Characterization of ground-motion; Site response; Probabilistic SHA and Inputs for engineers.

The program will go on up to the end of 2021.
