“Advances of International Collaboration on M9 Disaster Science: ProgressReports” World Bosai Forum Scientific Session (2019/11/12）
Theme: international research collaboration, M9 Cascadia Earthquake, University of Washington, CIGIDEN
Place: Sendai CityOn November 12, 2019, during the 2nd World Bosai Forum, the scientific session “Advances ofInternational Collaboration on M9 Disaster Science: Progress reports” was held, jointly organizedby IRIDeS/Tohoku University, University of Washington-Seattle (United States) and the ResearchCenter for Integrated Disaster Risk Management (CIGIDEN) (Chile).
This event was a continuation of international research collaboration between disaster scientists
from the three countries, connected to the M9 Project at the University of Washington. The M9
Project, https://hazards.uw.edu/geology/m9/, is a multi-year interdisciplinary project with the goalof reducing the catastrophic potential effects of a Cascadia megathrust (magnitude 9) earthquake
predicted for the west coast of the U.S., on social, built, and natural environments through theadvancement of methodologies, early warnings, and community planning. This scientific session
at the WBF was a follow-up event to the “Project Definition Workshop on Disaster Risk Science”
held 13-14 March 2019 at the University of Washington in Seattle. This ongoing collaboration
session has been supported by: IRIDeS, Tohoku University; the Core Research Cluster of DisasterScience,Tohoku University; and the University of Washington-Tohoku University: Academic OpenSpace (UW-TU:AOS)
This scientific session was organized for the purpose of sharing the progress of ongoinginternational collaboration between the members. Chaired by Assoc. Prof. Elizabeth Maly (DisasterInformation Management and Public Collaboration Division), the session started with opening
remarks from Prof. Randall LeVeque (UW), followed by updates on ongoing comparative researchon adaptive planning introduced by Assoc. Prof. Naoko Kuriyama (Kobe University), adaptive plansdeveloped in Washington State introduced by Prof. Daniel Abramson and PhD student Lan Nguyen(UW), and the example of recovery in Chile by Dr. Jorge Leon (Universidad Tecnica Federico Santa
Maria, Valparaiso and CIGIDEN, Chile). On behalf of Prof. Patricio Catalan (Universidad Federico
Santa Maria and CIGIDEN, Chile), Dr. Jorge Leon shared the advances of Probabilistic Tsunami
Hazard Analysis in Chile, followed by presentations about: real-time tsunami inundation anddamage forecasts by Prof. Shunichi Koshimura (Hazard and Risk Evaluation Research Division);
evaluation of tsunami loads on vertical evacuation structures by Assoc. Prof. Michael Motley (UW);and simulation-based surrogate models for probabilistic tsunami risk assessment and two-scaletsunami simulation by Prof. Kenjiro Terada (Regional and Urban Reconstruction ResearchDivision), Associate Prof. Shuji Moriguchi (Regional and Urban Reconstruction Research Division)
and Yuya Yamaguchi. Prof. Terada facilitated a discussion session, followed by closing remarks
from Prof. Koshimura. In addition to the presenters, other collaborators and participants fromIRIDeS included Assoc. Prof. Anawat Suppasri (Hazard and Risk Evaluation Research Division)and Assoc. Prof. Erick Mas (Hazard and Risk Evaluation Research Division) and from UW-Seattle,
Prof. Loyce Adams and Dr. Carrie Garrison-Laney.
The presentations included updates on ongoing research collaboration between the members ofdifferent institutions and published outcomes. Attended by 50 people, the session including lively
discussion during the question and answer portion, and led to the development of additional futureplans for research collaboration.
