Final Version of the EXTENDED ABSTRACTS ON-LINE has been released on DECEMBER 28, 2000 !!



ACES aims to develop realistic super-computer simulation models for the physics and dynamics of the complete earthquake generation process,and to assimilate new earthquake observations into such models. During the inaugural ACES Workshop held in 1999 in Brisbane and Noosa, Australia, five working groups were formed and initial WG goals were identified. At a subsequent Working Group Meeting held in Tokyo in January, 2000, two new WG's were established and WG leaders were nominated to animate WG interactions and organize WG sessions at major workshops.

The 2nd workshop to be held in October 2000aims to allow:

 - progress to be presented since the inaugural workshop including cooperative activities and complementary research towards the initial WG goals,

- discussions of the present state of the art in earthquake physics and computational science, and

- workshop-style interactions aimed at allowing interactive work to be achieved, fostering exchange of ideas between ACES participants and identifying new WG goals and/or activities.

By popular request after the inaugural workshop,the 2nd workshop will have no parallel sessions and will have more time for workshop style activities and discussions. Sessions are being organized by convenors.

Workshop themes
The major theme of the 2nd workshop is "Microscopic and macroscopic simulation of fault zone processes and evolution, earthquake generation and cycles, and fault system dynamics".
The theme will be addressed in a series of sessions (below). An additional special session will be held on collaborative software systems and models.

Session 1: Micro-physics underlying earthquake nucleation and frictional behaviour of complex fault zones: observations and simulation

Convenors: P. Mora (Australia), Y. Bai (China) & T. Tullis (USA) & T. Yamashita (Japan)

Session 2: Scaling physics and emergent behaviours at the micro and macro-scales: theory, simulation and observation

Convenors: W. Klein(USA), M-F. Xia (China), D. Sornette (France) & M. Ohnaka (Japan)

Session 3: Physically-based simulation of earthquake generation and the earthquake cycle

Convenors: S. Day (USA), Y-X. Zhang (China) & K. Hirahara (Japan)

Session 4: Simulation of earthquake rupture, wave propagation and standard models for different tectonic settings

Convenors: K. Olsen (USA), H. Igel (Germany) & T. Furumura (Japan)

Session 5: Assimilation of geodetic data and seismic activity data into simulation models

Convenors: A. Donnellan (USA), S-K. Zhou (China) & T. Sagiya (Japan)

Session 6: Earthquake hazard quantification in space and time: simulation based predictions, preliminary forecasting models, and forecast tests and evaluations

Convenors: X-C. Yin (China), D. Jackson (USA) & N. Hirata (Japan)

Session :
Collaborate software systems and models

ACES aims to develop realistic supercomputer simulation models for the physics and dynamics of the complete earthquake generation process, and to assimilate new earthquake observations into such models.
The simulation capability will provide a virtual laboratory to study earthquake behaviour and the earthquake cycle. This capability offers a new opportunity to gain an improved understanding of the earthquake nucleation process, precursory phenomena, and space-time earthquake patterns, and thus provides a means to develop improved models for earthquake hazard quantification and forecasting.

The Inaugural Workshop of ACES was held in Brisbane and Noosa in Australia in February,
