TsunamiReady
Communities
(as of January 7, 2005)
California
TsunamiReady Communities
- University
of California at Santa Barbara: The University of California
at Santa Barbara was the first higher learning institution to be recognized
as TsunamiReady. Situated on a coastal peninsula, UCSB is accessed (and
exited) through the use of two roadways that are both less than five
feet above sea level. Fault lines immediately offshore, coupled with
low lying areas surrounding the UCSB campus make this coastal area particularly
vulnerable to tsunami damage.
- Crescent
City, Calif.: Crescent City, California is vulnerable to tsunamis
because it is situated on a low-lying portion of a headland that concentrates
the energy of approaching tsunamis. This community's vulnerability has
been demonstrated by past events, most notably the 1964 tsunami that
resulted in 11 deaths — the only known tsunami fatalities to ever
occur in the lower 48 states. Crescent City was a good candidate for
TsunamiReady status because it is a well defined, concentrated community
with good evacuation routes, and because it had an existing culture
of tsunami awareness.
Oregon
TsunamiReady Communities
- Cannon
Beach, Ore.:
Cannon Beach is located on the northwest Oregon coast and is a popular
tourist destination and host to thousands of visitors every week. The
Cannon Beach Fire Department and city leaders have been very proactive
in tsunami education and outreach. They have established tsunami evacuation
routes, signage, inundation maps and marshalling areas in safe zones.
The community has six tsunami warning sirens, which are tested on a
monthly basis. This community conducts semi-annual tsunami and earthquake
drills.
- Manzanita,
Ore. (including nearby Nehalem, Ore. and Wheeler, Ore.):
These three communities are located on the northwest Oregon coast and
were just recognized as TsunamiReady in Oct 2004. Manzanita is also
a very popular tourist destination. These three small coastal communities
separated by only a few miles and worked jointly on their certification
because they share resources (e.g., 911 center, EOC, etc.) and back
each other up in terms of resources. The community leaders in these
communities have also been proactive in their preparedness activities.
They have established tsunami evacuation routes, signage, inundation
maps, marshalling areas and also conduct an effective tsunami education
and outreach program. They have three tsunami warning sirens and also
conduct semi-annual tsunami drills in the schools and communities.
Washington
TsunamiReady Communities
- Long
Beach, Wash.:
Long Beach, Wash. is located on the southwest coast of Washington State
and has a very proactive tsunami preparedness program. The Long Beach
peninsula is approximately 20 miles long and 3 miles wide. The county
and state government agencies and city leaders have conducted a very
aggressive tsunami education and outreach program to educate the residents
and visitors of the threat. They have established evacuation routes,
signage, marshalling areas, inundation maps, and conduct annual drills
with the local schools and communities.
- Ocean
Shores, Wash.: The
nation's first TsunamiReady community, Ocean Shores is the most visited
tourist community along the Washington coast. The community is vulnerable,
resting on a sand spit which is susceptible to liquefaction. Of note,
a major Cascadia Subduction Zone earthquake and subsequent tsunami event
would reach the shore of the community in less than 30 minutes.
- Quinault
Indian Nation:
The residents of the nation's first Native American TsunamiReady community
are vulnerable because the tribal population resides at the mouth of
the Quinault River. According to tribal legend, the January 26, 1700
tsunami inundated the tribe. A major Cascadia Subduction Zone earthquake
(such as the 1700 event) and subsequent tsunami event would reach shore
in less than 30 minutes.
Alaska
TsunamiReady Communities
- Seward,
Alaska: Seward was the first community to be recognized as
TsunamiReady in Alaska in January 2002. Seward’s mayor at that
time knew firsthand of the disastrous effects of tsunamis, because he
lived through the 1964 tsunamis as a young boy. During the Great Alaskan
Earthquake, a section of Seward’s waterfront slid into the bay
triggering a series of tsunamis that inundated the community a mere
20 minutes later. Twelve people were killed and the destruction was
extensive — 14 million dollars (in 1964 dollars).
- Kodiak,
Alaska:
Kodiak was recognized as TsunamiReady in February 2004, and like Seward,
the impetus for community preparedness is rooted in Kodiak’s painful
memories of the 1964 tsunamis which caused great destruction to the
island archipelago. Several Native villages were destroyed, and the
city of Kodiak was seriously damaged where 158 homes were destroyed.
Twenty-three people died in Chenega, about a third of the population
of the village, and there were eight deaths in Kodiak, six of which
were fisherman trying to save their boats from the 30-foot waves that
overtook the harbor and waterfront. The death toll was significantly
reduced in Kodiak due to residents moving to higher ground immediately
after the earthquake; however, approximately 600 people were made homeless
out of a population of 2,658.
- Homer,
Alaska: Homer was recognized as TsunamiReady in January 2003.
Homer is primarily a fishing, fish processing, trade and service center,
and it enjoys a considerable seasonal visitor industry. During summer
months, the population swells with students and others seeking cannery
or fishing employment. The community preparedness activities associated
with TsunamiReady are of particular importance in Homer, where they
are thought to be most vulnerable to locally generated tsunamis. Homer
is located across the inlet from a series of volcanoes, which are capable
of producing tsunamis through debris avalanches, lahars or pyroclastic
flows. Tsunamis generated in this way are likely to happen rapidly after
an eruption and potentially without warning.
- Sitka,
Alaska: Sitka
was recognized as TsunamiReady in July 2003. Sitka’s location
on the outer coast of the Alaskan Panhandle makes it vulnerable to local
tsunamis and Pacific-wide tsunamis. Four major earthquakes have been
linked to the nearby Queen
Charlotte-Fairweather fault system in the last century, one of which
triggered the largest tsunami in recorded history. The 1958 Lituya Bay
earthquake, which was felt as far away as Seattle, Wash., caused a large
rockslide depositing the contents of an entire mountainside into the
bay. The gigantic wave that resulted scoured the shores of the bay down
to bedrock and uprooted trees as high as 540 meters above sea level.
Fishing boats were carried on the wave at a reported height of at least
30 meters over the spit at the entrance to the bay and tossed into the
open ocean.
Hawaii
TsunamiReady Communities
- Maui
County, Hawaii:
Maui County is composed of the islands of Maui, Lanai, Molokai and Kahoolawe.
It was recognized as TsunamiReady in November 2004. The four islands
of Maui County are vulnerable to locally generated tsunamis, most likely
from the Big Island area of Hawaii, which would reach them within 15
to 20 minutes. Maui County is also vulnerable to Pacific-wide tsunamis
from the Aleutian Islands to the north and from Chile to the southeast.
These islands are vulnerable because of the large year-round tourist
population, the main seaport and airport are very close to the ocean,
and most of the main roads run near the ocean. Because of their vulnerability,
WFO Honolulu, the Pacific Tsunami Warning Center, and State and County
Civil Defense have conducted extensive outreach activities in the area.
Maps of the tsunami inundation zone and evacuation routes for all four
islands are in every telephone book.
- Kauai
County, Hawaii: Kauai County is composed of the islands of
Kauai and the privately owned island of Niihau. Kauai County was recognized
as TsunamiReady in October 2004. The biggest threat to the county is
from Pacific-wide tsunamis originating in the Aleutian Islands and Chile.
To a lesser extent, Kauai is vulnerable to a locally generated from
the Big Island of Hawaii. As with Maui County, Kauai is vulnerable because
of the large year-round tourist population, the main seaport and airport
are very close to the ocean, and most of the main roads run near the
ocean. Because of their vulnerability, WFO Honolulu, the Pacific Tsunami
Warning Center and State and County Civil Defense have conducted extensive
outreach activities in the area. Maps of the tsunami inundation zone
and evacuation routes for Kauai are in every telephone book.
