Evacuation Map
TSUNAMI
Evacuation for a distant tsunami will generally be
indicated by a STEADY 3-MINUTE SIREN BLAST and
an announcement over NOAA weather radio that the
local area has been put into an official TSUNAMI
WARNING. In isolated areas along beaches and bays
you may not hear a warning siren. Here, A SUDDEN
CHANGE OF SEA LEVEL should prompt you to move
immediately inland to high ground. If you hear the
3-minute blast or see a sudden sea level change, first
evacuate away from shoreline areas, then turn on your
local broadcast media or NOAA weather radio for further
information.

Be prepared! Assemble emergency kits with at
least a 3-day supply for each family member.
A DISTANT TSUNAMI will take four hours or more to
come onshore. You will feel no earthquake, and the
tsunami will generally be smaller than that from a local
earthquake. Typically there is time for an official warning
and evacuation to safety.

4. After evacuation, check with local emergency
officials if you think that you have special skills and
can help, or if you need assistance with locating lost
family members.
3. Stay away from potentially hazardous areas
until you receive an ALL CLEAR from local officials.
Tsunamis often follow river channels and dangerous
waves can persist for several hours. Local officials
must inspect all flooded or earthquake-damaged
structures before anyone can go back into them.
2. If you need help evacuating, tie something
WHITE (sheet or towel) to the front door knob. Make it
large enough to be visible from the street. If the
emergency is a distant tsunami, then help may arrive.
In the event of a local tsunami, it is unlikely that
anyone will help you, so make a plan and be prepared!
1. Evacuate on foot, if at all possible. Follow
evacuation route signs and arrows.
FOR BOTH LOCAL AND DISTANT TSUNAMIS:
A LOCAL TSUNAMI can come onshore within 15 to 20
minutes after the earthquake—before there is time for an
official warning from the national warning system.
Ground-shaking from the earthquake may be the
only warning you have. Evacuate quickly!
Recent research suggests that tsunamis have struck
the Oregon Coast on a regular basis. They can occur
any time, day or night. Typical wave heights from
tsunamis occurring in the Pacific Ocean, over the last 80
years, have been 20–45 feet at the shoreline. However,
because of local conditions a few waves have been
much higher—as much as 100 feet or more.
We distinguish between a tsunami caused by an
undersea earthquake near the Oregon coast (LOCAL
TSUNAMI) and an undersea earthquake far away from
the coast (DISTANT TSUNAMI).
A tsunami is a series of sea waves, usually caused by
a displacement of the ocean floor by an undersea
earthquake. As tsunamis enter shallow water near land,
they increase in height and can cause great loss of life
and property damage.

Seaside
Tsunami Evacuation Map:
The Oregon Department of Geology and Mineral
Industries is publishing this brochure because the
information furthers the mission of the
Department. The map is intended for emergency
response, and should not be used for site-specific
planning.
The evacuation zone on this map was developed
by the Oregon Department of Geology and
Mineral Industries in consultation with local
officials. It is intended to represent a worst-case
scenario for a local tsunami from an earthquake
near the Oregon Coast. The evacuation routes
were developed by local emergency officials and
reviewed by the Oregon Department of
Emergency Management.
