■Earth Systems Science Computational Centre (ESSCC), The University of Queensland :

ESSCC, formerly named Queensland University Advanced Centre for Earthquake Studies (QUAKES), conducts research on the physics of earthquakes and solid earth processes from the micro to global scales using supercomputer simulation. Earthquake nucleation and fault behaviour is controlled by microscopic interactions and group behaviour of rock grains along faults. The QUAKES group of ESSCC is focussed on simulation based research to study the nonlinear physics of interacting fault systems and micro-mechanics of fault zones. Part of this work aims to fill a fundamental gap in the knowledge of the earthquake generation process by developing a microscopic based numerical simulation capability (LSMearth).

A new integrated CoE for observational and computational earth science with the objective of building an advanced research and education sytem that can promote effectively study of future variations predictability of a multi-sphere earth system in which processes with different rules intertwine intricately in different space-time scales, based upon verification of necessity and randomness of the earth evolution process.

■ Research Organisation for Information Science and Technology (RIST):

Governmental organisation responsible for the national Earth Simulator Project in Japan under Science and Technology Agency to model earth processes (ocean, atmosphere, solid-earth).

■ Crustal Activity Modelling Program (CAMP):

Multi-institutional program within Japan's Earth Simulator Project. Institutions: Tokyo University, Earthquake Research Institute, Geographical Survey of Japan, Building Research Institute, National Research Institute for Earth Science and Natural Disaster Prevention.
