Project Definition Workshop on M9 Disaster Science
March 13-14, 2019
The goal of this two-day workshop is to initiate new international collaborations on particular aspects of M9 Disaster Science, topics related to a Magnitude 9 subduction zone earthquake and the resulting tsunami and landslides. Topics of particular interest include i) Probabilistic tsunami hazard assessment (PTHA), ii) Early warning systems, iii) Observations and remote sensing, iv) Hazard modeling, and v) Community planning.
The workshop will bring together researchers who study potential M9 events on
the Cascadia Subduction Zone with potential collaborators having similar interests
from Japan and Chile.
Several Japanese researchers from Tohoku University and the
International Research Institute of Disaster Science
(IRIDeS)
will participate, along with a number
of researchers involved with the Chilean
Research Center for Integrated Disaster Risk Management
(CIGIDEN).
Many workshop participants will also be joining the
M9
Project Final Stakeholders Workshop on March 12, 2019.
Post-workshop updates:
- Following this successful workshop, several participants attended the
World Bosai Forum in Sendai, Japan in November, 2019. This conference
on disaster hazards and resiliance
included a special session on the M9 collaborations. The
slides from that session and a session report
publication include some updates regarding on-going collaborations.
- On March 1-2, 2020, a field trip to coastal Washington communities took
place to follow up on some of the workshop activities. This is described
in the workshop report linked below.
- This Workshop Report
was submitted to the
UW Global Innovation
Fund, and also includes some photographs.
Participants:
The list of break-out groups
for the first afternoon now has participants listed, in many cases with a link
to their one-page lightning talk self-introduction slide.
All participant slides
Support
The workshop is supported in part by the
the UW / Tohoku University Open
Academic Space (UW-TU:AOS) project and the
UW Global Innovation Fund,
with travel support also provided by both Tohoku University and CIGIDEN.
Additional funding has been provided by the
UW M9 Project
(from an NSF Hazard SEES grant), the
Department of Applied Mathematics,
and the
Department of Civil and Environmental Engineering.
Meeting space is provided in part by
the eScience Insitute.

Optional field trip to
Port Townsend and
Discovery Bay.
This trip will be led by Brian Atwater and Carrie Garrision-Laney.
[Itinerary and information]
In Port Townsend we will have lunch and take a look at the latest
tsunami
inundation maps recently published by the State of Washington.
In Discovery Bay we will walk out into the marsh to view the evidence of past
earthquakes and tsunamis.
Sandy tsunami deposits at Discovery Bay record as many as nine
tsunamis between 2,500 and 300 years ago.

further information about the day and what to wear.
