Tsunamis appear significantly different from a common wave. Those observing
a tsunami will likely agree that these dangerous waves are more comparable to a
fast moving tide crashing into land. Common waves are wind-driven, whereas
tsunamis are powered by a geological force. The initial wave of a tsunami is
extremely tall; however, most damage is not sustained by this wave. It’s the
power behind the waves, the endless rushing water that causes devastation and
lost of life.
Once a tsunami hits land, it may continue to travel for several miles
inland. Small islands hit by a tsunami are left unrecognizable. Escaping a tsunami
is nearly impossible. As the water rushes toward land, it leaves very little
time to map an escape plan. When the December 2004 tsunami occurred, the shore
was lined with vacationers. As the water quickly receded, and came rushing back
to the shore, many tourist and locals were unable to seek shelter in nearby
hotels and businesses. Many underestimate the power behind killer waves.
Tsunamis include series of waves. After the initial wave, several smaller
waves will follow, crashing into the surface like a speeding vehicle. The
period between waves varies. In some cases, four or five smaller waves may
immediately follow the first wave. However, it is possible for smaller tsunamis
to continue days after initial impact.
Signs of an Approaching Tsunami
Earthquake
Observing bubbles in
the ocean, may appear as if the water is boiling
Unusually warm water
Ocean has a foul odor
Ocean water may
slightly burn skin
Roaring noise coming
from the ocean (may indicate tsunami miles away)
Ocean may suddenly
recede
As tsunami
approaches, the wave may appear red from a distance
Seeking shelter on high ground is the key to surviving a tsunami. Once a
tsunami hits land, the water will begin to slowly level. However, fast moving
water flooding the mainland will bring down anything in its path. Do not
attempt to drive a car or run faster than a tsunami.
