Action 5.1.2 : Recurrence models for low seismicity areas

Technical Issue

Simple double truncated GR model may not be most adequate to describe seismicity

Proposed Approach

  • Study alternative models to truncated GR: models less sensitive to Mmax
  • Assess influence of zones and discretization, develop zones with uniform occurrence rates by classification k-means clustering for French territory
  • Develop composite (hybrid) models distinguishing moderate and high magnitude rates, construct and assess impact of different aggregates for moderate to high magnitudes by simulation (to be confirmed)
