Background

The Taiwan-Japan-New Zealand Seismic Hazard Workshop is an annual collaborative event that brings together experts from Taiwan, Japan, New Zealand, and other countries to discuss advancements and challenges in seismic hazard assessment. Initiated in 2013, the workshop has evolved to address various topics, including probabilistic seismic hazard assessment (PSHA), ground motion prediction, active fault studies, and risk analysis. The collaboration aims to enhance the understanding of seismic hazards in island arc regions, improve national seismic hazard models, and develop strategies for disaster resilience. Each year, the workshop features presentations, discussions, and field trips, fostering knowledge exchange and strengthening partnerships among participating countries.

Goals and/or Strategic Focus

The Taiwan-Japan-New Zealand Seismic Hazard Workshop aims to enhance seismic hazard assessment through international collaboration, focusing on:

  • Advancing Probabilistic Seismic Hazard Assessment (PSHA): Developing and refining PSHA methodologies tailored to the complex tectonic settings of Japan, New Zealand, and Taiwan.
  • Integrating Multidisciplinary Research: Combining geological, seismological, and engineering studies to improve the accuracy of seismic hazard models.
  • Validating Hazard Models: Utilizing data from recent significant earthquakes to assess and enhance the reliability of national seismic hazard models.
  • Fostering Knowledge Exchange: Providing a platform for sharing research findings, discussing challenges, and exploring innovative approaches to seismic hazard assessment.
  • Promoting Disaster Resilience: Applying research outcomes to inform risk mitigation strategies and strengthen infrastructure resilience against seismic events.

By focusing on these strategic areas, the workshop seeks to improve earthquake preparedness and contribute to the safety and resilience of communities in seismically active regions.

Objectives

The Taiwan-Japan-New Zealand Seismic Hazard Workshop has several key objectives:

  • Enhancing Probabilistic Seismic Hazard Assessment (PSHA): The workshop aims to improve PSHA methodologies by addressing challenges specific to island arc regions like Japan and Taiwan. This includes refining seismic activity models to account for low-probability earthquakes and developing robust ground motion evaluation techniques.
  • Fostering International Collaboration: A central goal is to strengthen partnerships among Japan, New Zealand, Taiwan, and other nations. By sharing experiences and research findings, the workshop seeks to collectively advance seismic hazard assessment practices.
  • Validating and Improving Hazard Models: The workshop provides a platform for participants to evaluate existing National Seismic Hazard Maps (NSHMs) against recent earthquake data. This collaborative validation process aims to enhance the accuracy and reliability of these models.
  • Promoting Knowledge Exchange: Through presentations, discussions, and field trips, the workshop facilitates the sharing of the latest research and practical experiences. This exchange is crucial for addressing common challenges in seismic hazard assessment and for developing innovative solutions.
  • Advancing Risk Assessment and Mitigation: By integrating geological, seismological, and engineering research, the workshop aims to inform risk mitigation strategies. This holistic approach is essential for enhancing infrastructure resilience and disaster preparedness in seismically active regions.

Collectively, these objectives guide the workshop's efforts to improve earthquake preparedness and contribute to the safety and resilience of communities in seismically active areas.
