APEC Cooperation for Earthquake Simulation

ACES

ACES is a multi-lateral grand challenge science research cooperation of APEC (the Asia Pacific Economic Cooperation). The project is sponsored by Australia, China, Japan and USA and involves leading international earthquake simulation and prediction research groups.

ACES aims to develop realistic supercomputer simulation models for the complete earthquake generation process, thus providing a "virtual laboratory" to probe earthquake behavior. This capability will provide a powerful means to study the earthquake cycle, and hence, offers a new opportunity to gain an understanding of the earthquake nucleation process and precursory phenomena.

The project represents a grand scientific challenge because of the complexity of phenomena and range of scales from microscopic to global involved in the earthquake generation process. It is a coordinated international effort linking complementary nationally based programs, centres and research teams.

In 2003, it was agreed to work towards establishment of a frontier international research institute on simulating the solid earth named the international Solid Earth Virtual Research Observatory institute (iSERVO).

		Mission

	to develop realistic numerical simulation models for the physics and dynamics of the complete earthquake generation process and to assimilate new earthquake observations into such models,
	to foster collaboration between the relevant complementary programs of participating APEC member economies,
	to foster development of the required research infrastructure and research programs.

		Brief description

Earthquakes are one of the most costly and deadly natural disasters. APEC member economies are struck by the vast majority of the world's earthquakes and have a particularly high earthquake risk (see the world seismicity map). This has resulted in more than 800,000 deaths in APEC member economies of the approximately 1.3 million deaths associated with earthquakes this century.

The scientific method relies on development of a theoretical framework or simulation model describing nature. While no such model exists for the complete earthquake generation process, conceptual developments in understanding earthquake physics, numerical simulation methodology and advances in High Performance Computing offer the possibility to develop such models. The APEC Cooperation for Earthquake Simulation (ACES) would capitalize on this new opportunity and the complementary strengths of the earthquake research programs of individual APEC member economies.

It aims to develop numerical simulation models for the complete earthquake generation process (see a snapshot of a numerical earthquake simulation), to assimilate new earthquake observations into such models, to foster collaboration between the relevant programs of participating member economies, and to foster development of required research infrastructure and research programs.

Development of such simulation models represents a grand scientific challenge because of the complexity of phenomena and range of scales involved from microscopic to global (see the figure). The models would provide powerful new tools for studying earthquake precursory phenomena and the earthquake cycle. They would have direct application to earthquake hazard studies and earthquake engineering, and the potential to yield spin-offs in sectors such as mining, geophysical exploration, high performance computing, material science, engineering and geotechnical.

		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).
