Updated Washington Tsunami Design Zone for the
New Washington State Building Code
By the Washington Geological Survey
(Continued from page 8)
The Washington Geological Survey (WGS) investigates the potential impacts of tsunamis on Washington State. From
this research, WGS has developed models that simulate specific aspects of how a tsunami could affect waterways and
inundate land. These include quantifying inundation (flooding caused by a tsunami), current velocities (the speed that
water will flow during a tsunami), arrival times of waves, and wave duration for a range of tsunami scenarios.
Building Codes and the Washington Tsunami Design Zone (WA-TDZ)
To make critical structures such as hospitals, police stations, and vertical evacuation refuges more resilient to tsunamis,
the latest update to the Washington State Building Code (the 2021 International Building Code with amendments)
requires certain structures located in areas affected by tsunamis to adhere to specific engineering and construction
standards. To determine if a location could be inundated by a tsunami—and therefore must adhere to these higher
engineering standards—engineers use a product from the Washington Geological Survey called the Washington
Tsunami Design Zone (WA-TDZ). The WA-TDZ delineates inundation areas and compiles the best available tsunami
modeling from WGS and from partners for this purpose.
Accessing the WA-TDZ
The WA-TDZ is hosted on the WGS website on its own dedicated page.

Tsunami Safety Rules Flyer in Braille Now Available in English
and Spanish for the Visually Impaired Community in the Caribbean
By Glorymar Gomez and Christa von Hillebrandt-Andrade, International Tsunami Information Center-
Caribbean Office and Gladymar Aponte, Industries for the Blind
IFB Solutions (Industries for the Blind) in Cabo Rojo, Puerto Rico, is a sewing company that specializes in tailoring
ARMY uniforms. Many of their employees have severe visual impairments and are experienced machine operators. For
the CARIBE WAVE 24 tsunami exercise on March 21, eleven of these employees received an orientation on
earthquakes and tsunamis and recommendations in the case of a tsunami threat. All employees were given a copy of the
Tsunami Safety Rules flyer in Braille, for them to read and provide feedback on the content. These tsunami flyers, the
first of its kind, were produced by the Caribbean Office of the International Tsunami Information Center. Thi j
educational material is available in English and Spanish, and copies can be shipped by request. ITIC-CAR coordinated this
activity with Gladymar Aponte from IFB Human Resources and Adam Ramos from IFB Production. For copies of the

Santa Cruz Harbor, California Tabletop Exercise March 6, 2024
By Yvette LaDuke, California Governor's Office of Emergency Services (Cal OES)
On March 6, 2024, the California Tsunami Program (CA Governor's Office of Emergency Services and CA Geological
Survey) hosted a tabletop exercise for response officials in Santa Cruz County. The exercise focused on the Santa Cruz
Harbor tsunami response process and the role county officials hold in supporting harbor area tsunami response.
Participants in the exercise included Santa Cruz Harbor, County Fire, County Sheriff's Office, City Fire, City Police,
County Office of Emergency Services, County 9-1-1 Dispatch, National Weather Service, CA State Parks, U.S. Coast
Guard Station Monterrey, and Marine Exchange. r
Participants had robust discussion during the exercise which focused on the
following objectives: f '
• NTWC alerts and California's tsunami response process.
-4
• Local procedures/actions when receiving tsunami alerts. r
• Processes for communicating tsunami alerts and messaging to response
r
personnel and the public.
• Operational coordination and information sharing, and methodology for securing and evacuating the harbor and
surrounding area.
• Gaps in available resources and coordination needs for harbor evacuation during tsunamis.
Information shared during the tabletop exercise will be used by local officials to update their tsunami response plan and
protocols which will be tested during a full-scale tsunami evacuation exercise planned for March 2025. This exercise will
be the first time California has hosted an evacuation exercise for people who live on their boats or operate a business
within a harbor or marina.

Evacuation Route Wayfinding Assessment
By Elyssa Tappero, Washington Emergency Management Division
Washington State has completed an evacuation wayfinding assessment years in the making thanks to two rounds of
funding from the National Tsunami Hazard Mitigation Program (NTHMP) and a partnership with the University of
Washington.
Starting in 2022, Washington Emergency Management Division (WA EMD) partnered with the University of Washington
to have teams of undergraduate and graduate students assess the state's 1,050+ miles of mapped tsunami evacuation
routes. This assessment provided vital information about where more signs were needed and the conditions and
accessibility of designated evacuation routes.
Students collected a wealth of data in the field, including photos, GPS coordinates, locational accuracy, and conditions of
current signage; GPS coordinates and photos of all locations where new signs were recommended; and notes and

Regarding communities, several were observed to have participated by organizing their own self-managed evacuation
drills, without intervention from Emergency Management or our office. In the municipality of Patillas, the GUPE
organization (Guardarraya Unidos por un Patrimonio Educativo, Inc., name in Spanish), from the "La Guardarraya"
community, organized an evacuation drill in which residents, several agencies, and local organizations participated. In the

educating themselves on the topic of tsunamis. Many coastal communities, such as San Jose in Mayaguez and Villa del
Carmen in Ponce, organized a tsunami evacuation drill. It was observed that many institutions outside the tsunami
evacuation zone also participated in Caribe Wave, recognizing the importance of being prepared for the danger of
tsunamis.
Finally, 27 out of 41 municipalities with siren systems activated their mass alert systems as part of the exercise. At the
state level, E.A.S., W.E.A., NOAA Weather Radio, and other alert systems were activated as part of the communication
protocol in case of a tsunami. All PTWC alert messages were received and disseminated by the Tsunami Warning Focal
Points (TWFP) on time according to the communication protocol. Although we still have a long way to go, we can be
certain that we are headed in the right direction.

simulated products included information on earthquake location, magnitude, estimated wave arrival time/heights, and
potential areas under threat and forecasted wave heights.
Full-scale exercises, drills, seminars, and communication tests were some of the many activities that were organized by
the individual countries for CARIBE WAVE. According to the TsunamiZone website, the majority of the participants
from across the region were from K-I2 Schools and Districts. High levels of participation were also recorded for State
Government, Colleges, and Universities, as well as a significant number of businesses, health care organizations, hotels,
tourism groups, volunteer radio groups, and people with disabilities. Puerto Rico had 135,343 people registered, while
the United States Virgin Islands had a total of 23,670 registrants (more than 20% of their total population). Details on
CARIBE WAVE were widely disseminated, with many organizations and individuals sharing their participation through
social media platforms.
