Inaugural ACES Workshop

31 January - 5 February, 1999, Brisbane & Noosa, Qld, Australia

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.

ACES workshops are the principal forum for international scientists of the cooperation to interact. The first workshop aims to allow the working groups to form and for researchers to become familiar with the complementary work of other participants, discuss the state of the science, and identify initial working group goals and/or activities.

Workshop themes

Themes of the workshop will be addressed in a series of sessions related to the five Working Groups of ACES. Click on the session numbers to obtain detailed information regarding each session.

Venue

The workshop will be held at The University of Queensland in the city of Brisbane - a delightful city located on the picturesque Brisbane river and at Noosa Heads - a vibrant tropical coastal town just north of Brisbane, renowned for its beautiful beach, surfing, and unspoiled coastal headland national reserve.
