Working Group 3

Macro-scale simulation / Earthquake generation and cycles

WG leaders

• Kazuro Hirahara (Nagoya University, Japan)
• Steve Day (San Diego State University, USA)
• Yong-Xian Zhang (CAP, CSB, China)

Aims

• Develop macroscopic domain numerical simulation models for the earthquake generation process (based on continuum mechanics) including the complete cycle from tectonic loading, quasi-static rupture nucleation, to dynamic rupture, to fault lithification and healing.
• Gain understanding of:
  • the earthquake cycle & crustal movement, and
  • seismicity & spatio-temporal patterns of interacting fault systems.

Functions

Construction of macroscopic domain numerical simulation models for long time scale processes and the earthquake cycle. Study of macro-phenomena including stress transfer, long range inter-actions in fault systems, effective constitutive laws (consequences), dynamic rupture processes, and the earthquake cycle.
