It could save their lives!

If
you are in school and you hear there is a tsunami warning, you
should follow the advice of teachers and other school personnel.
- If you are at home and hear there is a tsunami warning, you
should make sure your entire family is aware of the warning.
Your family should evacuate your house if you live in a tsunami
evacuation zone. Move in an orderly, calm, and safe manner to
the evacuation site or to any safe place outside your evacuation
zone. Follow the advice of local emergency and law enforcement
authorities.
- If you are at the beach or near the ocean and you feel the
earth shake, move immediately to higher ground. DO NOT wait for
a tsunami warning to be announced. Stay away from rivers and
streams that lead to the ocean as you would stay away from the
beach and ocean if there is a tsunami. A regional tsunami from a
local earthquake could strike some areas before a tsunami
warning can be announced.
- Tsunamis generated in distant locations will generally give
people enough time to move to higher ground. For locally
generated tsunamis, where you might feel the ground shake, you
may only have a few minutes to move to higher ground.
- High,
multi-story, reinforced concrete hotels are located in many
low-lying coastal areas. The upper floors of these hotels can
provide a safe place to find refuge should there be a tsunami
warning and you cannot move quickly inland to higher ground.
Local Civil Defense procedures may, however, not allow this type
of evacuation in your area.
Homes
and small buildings located in low lying coastal areas are not
designed to withstand tsunami impacts. Do not stay in these
structures should there be a tsunami warning.
- Offshore reefs and shallow areas may help break the force of
tsunami waves, but large and dangerous waves can still be a
threat to coastal residents in these areas. Staying away from
all low-lying coastal areas is the safest advice when there is a
tsunami warning.
IF YOU ARE ON A SHIP OR BOAT
-
Since tsunami wave activity is imperceptible in the open ocean,
do not return to port if you are at sea and a tsunami warning
has been issued for your area. Tsunamis can cause rapid changes
in water level and unpredictable dangerous currents in harbors
and ports.
- If there is time to move your boat or ship from port to deep
water (after you know a tsunami warning has been issued), you
should weigh the following considerations:
- Most large harbors and ports are under the control of a harbor
authority and/or a vessel traffic system. These authorities
direct operations during periods of increased readiness (should
a tsunami be expected), including the forced movement of vessels
if deemed necessary. Keep in contact with the authorities should
a forced movement of vessels be directed. - Smaller ports may
not be under the control of a harbor authority.
If
you are aware there is a tsunami warning and you have time to
move your vessel to deep water, then you may want to do so in an
orderly manner, in consideration of other vessels. Owners of
small boats may find it safest to leave their boat at the pier
and physically move to higher ground, particularly in the event
of a locally-generated tsunami. Concurrent severe weather
conditions (rough seas outside of the harbor) could present a
greater hazardous situation to small boats, so physically moving
yourself to higher ground may be the only option.
- Damaging wave activity and unpredictable currents can affect
harbors for a period of time following the initial tsunami
impact on the coast. Contact the harbor authority before
returning to port making sure to verify that conditions in the
harbor are safe for navigation and berthing.
As dangerous as tsunamis
are they do not happen very often. You should not let this
natural hazard diminish your enjoyment of the beach and ocean.
But, if you think a tsunami may be coming, the ground shakes
under your feet or you hear there is a warning,
tell your relatives and friends, and Move Quickly to higher
ground!
