Tsunami
Information |
|
Tsunami (sea wave with high
velocity) are associated with
earthquakes and volcanic eruptions. In PNG they
occur along the
coastline of the Solomon Sea endangering coastal
settlements. Little was known about tsunami and
the latest tsunami in 1998 which killed about
3,210 people became an eye opener for all Papua
New Guineans. As a result people in the Niugini
Islands region moved to higher grounds when the
tsunami occurred in 2000.

Emergency
Information on Tsunami |
-
Tsunamis are caused by an underwater
disturbance - usually an undersea earthquake.
Landslides, volcanic eruptions, and even
meteors can also generate a tsunami.
-
Tsunamis can originate hundreds or even
thousands of kilometres away from coastal
areas. Local geography may intensify the
effects of tsunami. Areas at greatest risk
less than 50 feet above sea level and within 1
mile of the shoreline.
-
An offshore tsunami
refers to earthquake triggered tsunami from
outside of the 200 nautical miles from the
territory of PNG. This includes tsunami that
is triggered from the other side of Pacific
ocean like western coasts of the continent of
America. Any immanence of an offshore
tsunami, there some ample time for the
international and PNG Government authorities
to alert or warn PNG citizens to evacuate.
-
Local tsunami refers to
earthquake triggered tsunami from within the
200 nautical miles of the territory of PNG or
close to the coastal villages of PNG. Any
immanence of a local tsunami, there is no time
for the international and PNG Government
authorities to alert or warn PNG citizens to
evacuate.

-
People who are near the seashore
or on the island during a
strong earthquake should listen to a radio for
a tsunami warning and be ready to evacuate at
once to higher ground.

-
Rapid changes in the water level are an
indication of an approaching tsunami
-
Tsunamis arrive as a series of successive
"cress" (high water level) and "troughs" (low
water levels). These successive crests and
troughs can occur anywhere from 5 to 90
minutes apart. They usually occur 10 to 45
minutes apart.
