Overview || Agenda || Attendees


The APEC Cooperation on Earthquake Simulations (ACES) is a multi-lateral grand challenge science research cooperation of APEC (the Asia Pacific Economic Cooperation). The ACES program is fundamentally a coordinated international effort linking complementary nationally based programs, centers and research teams, whose mission is:

1. 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,
2. To foster collaboration between the relevant complementary programs of participating APEC member economies,
3. To foster development of the required research infrastructure and research programs.

The meeting will consist of plenary sessions plus half-day sessions related to the ACES working groups:

WG 1: Microscopic simulation
WG 2: Scaling physics
WG 3: Macro-scale simulation/Earthquake generation and cycles
WG 4: Macro-scale simulation/Dynamic rupture and wave propagation
WG 5: Computational Environment and Algorithms
WG 6: Data assimilation and understanding
WG 7: Model applications

In addition to the oral presentations, participants will be invited to bring posters on their research. Meeting attendees are encouraged to submit an extended abstract for the meeting. Guidelines for abstracts will be provided to accepted participants after February 15th. Full peer-reviewed papers will be published following the meeting.

The complete agenda is now online as well as a list of Participants and lodging information.The conference rate for hotel rooms is $145/night (plus tax).
