The Great Wave

1
The Great Wave
The tsunami has demonstrated that Nature, and
not Mankind, is the real master.

A clock is stopped on Sunday in the town of Banda
Aceh in Indonesia boxing day DEC 26th 2004 at
the time the wave hit
3
Massive waves triggered by an earthquake surged
into coastal communities in Asia and east Africa
with devastating force. Hitting Indonesia, Sri
Lanka, Thailand and India hardest, the deadly
waves swept an estimated 300,000 people to their
deaths.

The 9.0 magnitude quake struck about 7 a.m. (0000
GMT) on Sunday December 26 about 100 miles from
the western coast of Indonesia's Sumatra
island. It is the fourth strongest since
recordings of magnitude began in 1899, tying a
1952 quake in Kamchatka, Russia.

Stage 1 Formation of a Tsunami
7
Tsunamis are formed by a displacement of water --
a landslide, volcanic eruption, or, as in this
case, slippage of the boundary between two of the
earth's tectonic plates. The December 26 tsunami
was caused by slippage of the boundary between
the India and Burma plates. The Indian plate is
moving to the northeast at 2 inches (5 cm) per
year relative to the Burma plate.

Stage 2 Tsunami approaches Coasts

The power of tsunamis only becomes clear as they
approach shallow water along the coast

But from the beaches few people recognised the
danger of the white line on the horizon
15
Common questions to consider Why didnt people
run away? I dont understand how 300,000 people
could have all died from a wave?

Stage 4 Secondary Effects of Tsunami
31
Indonesia At least 100,000 people are believed
dead in Aceh and Northern Sumatra, while some
500,000 people are sheltering in scattered
refugee camps across the province, the UN
estimates. Large swathes of Banda Aceh, Meulaboh
and Calang and their outlying districts are
completely destroyed. To speed up aid delivery,
the Australian Air Force has assisted in
improving air traffic control at Banda Aceh
airport. The UN is moving supplies by truck along
the road from the regional capital Medan. Other
agencies are shipping relief by sea to outlying
islands. The ports of Belawan and Lhokseumawe are
the nearest harbours undamaged by the tsunami.
32
Thailand Worst affected districts are Phang Na,
Ranong, Trang, Phuket and Krabi where more than
5,000 people are believed to have died. These
provinces form the heart of Thailand's tourist
industry. Some 27 hotel complexes in Phuket alone
have been destroyed, the Thailand government
reports. At least 2,400 fishing boats have been
destroyed and 54,000 farm animals killed,
according to official Thai estimates. Some 6,000
houses, 50 schools and 19 government buildings
are also reported to be damaged or destroyed.
33
The World Health Organization's David Nabarro
told CNN that survivors were at risk of
diarrhoea, respiratory infections and
insect-borne diseases that could result in "quite
high rates of death," but he quickly added that
the living are in more danger from other
survivors than from the dead.
34
A worldwide aid effort in the aftermath of the
Indian Ocean tsunami means supplies are pouring
into the region. They include food, water,
shelter, blankets and basic medicines. Aid
agencies are co-ordinating the delivery of
relief, beginning with aircraft and ships
bringing in large consignments which are then
broken down and distributed by road or
helicopter. But getting aid to the worst hit
areas is proving difficult. Many roads and
airstrips have been damaged, flooded or blocked
by debris. Bridges and harbours have also been
washed away. Even when planes have room to land,
local air traffic control systems can be in
disarray. Because of their versatility,
helicopters are a vital part of the relief
effort.
35
Drinking water has also been polluted in many
areas hit by the tsunami. Initially bottled water
is being supplied but engineers are also working
to establish reliable clean water sources in the
worst hit areas. Buckets and hand pumps are also
vital supplies and longer term responses include
the chlorination of contaminated wells.
36
An often unreported tragic effect of the Tsunami
was the psychological effects of the loss of
family and friends. This could lead to huge
personal problems for people in the category of
trauma. One of the saddest stories in the
aftermath came from reports that many parents
unable to cope with the loss of their child had
simply taken other lost or orphaned children.
This was often the case in areas which were
poorly organised and monitored.
