Shaky 11th ACES (APEC Cooperation for Earthquake Science) International Workshop !

Icebreaker magnitude 4.6 quake near Blenheim

The 11th ACES International Workshop was held in Blenheim, New Zealand. International attendees were greeted with a magnitude 4.6 quake during the icebreaker. ACES is a multi-lateral grand challenge science research cooperation of APEC ( The project is supported by Australia, China, Japan, and USA (core members) as well as Canada, Chinese Taipei, New Zealand, and South Korea (members). Topics included seismic and tsunami hazard, earthquake nucleation, dynamic rupture simulations and active fault geology. I presented on “High-frequency Ground-shaking Simulations for Alpine Fault Earthquake Scenarios” highlighting the need for ground motion simulations towards Alpine Fault hazard estimate, the uniqueness of the fault geometry, and the urgent opportunity to study a shallow major plate boundary fault at the end of its seismic cycle !
