Tsunami
alarm: desi model or global club?
Posted online: Monday, January 03, 2005 at 0000 hours IST
Is technology the ultimate solution? Could a monitoring and warning system have
prevented the large-scale destruction that one witnessed last week? Why didn’t
India install a warning system so far? These are among the questions being
asked, both within and outside the scientific community, post-Tsunami. Even as
answers are few and far between, Tsunami has come as a wake-up call for the
government. While relevance of technology in predicting Tsunami is one of the
key issues being debated right now, a way forward is clearly being chalked out.
For
one, the Union ministry of science and technology is planning to hold a
brainstorming session sometime this month with National Geophysical Research
Institute, National Institute of Oceanography and Department of Ocean
Development for devising an appropriate Tsunami warning system. Also, steps are
being chalked out to strengthen the Indian station in Antarctica, Maitri, to
monitor seismicity in and around Antarctica and Indian Ocean.
Commitment
has come from the minister for science and technology and ocean development
Kapil Sibal already. He is on record saying that proper logistics for
monitoring and warning will be put in place, even though Tsunami is a rare
occurrence.
The
initiatives that the establishment wants to roll out include undertaking deep
ocean assessment and reporting system, coastal barometry, and increasing the
number of data buoys in the surrounding seas from existing 20 to 30. The buoys
are expected to monitor 6 km below the ocean surface, by connecting the aquatic
tidal gauges to a satellite. The project cost: a mere Rs 125 crore!
Meanwhile,
there’s a difference in view as far as joining the Tsunami warning system in
the Pacific is concerned.
For
instance, the US Geological Society (USGS) has alleged that the Tsunami-hit
countries has not put in place any warning system for mitigating the disaster.
USGC spokesperson Carolyn Bell is reported to have said: “We support the
Tsunami warning system in the Pacific only. Of course this earthquake was not
in the Pacific Ocean.” According to her, creating a Tsunami warning centre in
the Indian Ocean will be a challenge. “This crosses so many countries and so
many boundaries in that part of the world and the warning system would have to
be so geographically diverse. We’re talking about educating people to what the
warning means, what you have to do,” she says.
India
thinks differently. Mr Sibal says that India will not be a member of the
Pacific Tsunami Warning Centre, a body set up exclusively for the Pacific Rim
countries. “Being a member of this body will not help us as the mandate of the
body is for the specific region. Our seismic zone is Indo-Australian plate as
distinct from the Pacific plate. We should therefore ask for relevant data from
them and construct our own model for monitoring and forecast,” he says. The
minister also said that India will network with Indonesia, Thailand and Myanmar
in future for exchange of relevant data. Whatever the arrangement, experts
argue that a suitable monitoring system could have mitigated some of the
colossal damages. Though earthquakes and volcanic eruptions cannot be predicted
on a short-term basis, the Tsunami effect, which takes longer time to reach
distant places, can be predicted at ease, they say.
But,
the Indian government insists that the country did not opt for such a system as
Tsunami has not been a frequent occurrence in the region. According to Mr
Sibal, the first Tsunami killed the forces of Greek invader Alexander the
Great, and the second Tsunami occurred in 1883. Secretary in the department of
ocean development Harsh K Gupta agrees that Tsunami is rare.
Noted
geologist, Dr George Pararas-Carayannis, counters: "Destructive Tsunamis
are not uncommon in the Bay of Bengal or along the Sunda Trench. On June 26,
1941, a devastating earthquake in the Andaman Sea, with a Richter magnitude
greater than 8.0 generated a major Tsunami that killed more than 5,000 people
on the east coast of India. However, at that time, the media incorrectly
attributed the deaths and damages to storm surges rather than to a Tsunami
generated by an earthquake. Many more deaths must have occurred but were not
reported."
He adds
that the region where the earthquake took place marks the boundary where great
tectonic plates of India and Australia collide with the Sunda and the Eurasian
plates. It is the same place where large catastrophic earthquakes and volcanic
explosions and Tsunamis have occurred for millions of years.
Coming
to the basics, the Tsunami of December 26 is the fourth largest trembler in the
world since 1900 and Asia's worst earthquake since 1970. The Tsunami effect
touched even the east coast of Africa on the same day. According to the India
Meteorological Department (IMD), Tsunami effect took about two hours to reach
Port Blair in Andaman & Nicobar Islands and
three-and-half hours to reach the Chennai coast.
For
those who joined in late, Tsunami is a Japanese word, pronounced as
"tsoo-nah'-mee". `Tsu' means harbour and `nami' means wave. The
phenomena, Tsunami, is a series of large waves of extremely long wavelength or
activity near the coast or in the ocean.

US-based experts predict another tsunami

NEW DELHI, DEC 30: The government has been on the horns of a dilemma after some
foreign experts predicted another tsunami.
The
home ministry has issued an alert to five affected states and Union
territories.
It has also issued a warning to Lakshdweep, so far untouched. Following the
alert notice, the affected states are evacuating people from the coast.
But
Union minister for science and technology and ocean development Kapil Sibal has
denounced these predictions as ‘hogwash.’
Mr
Sibal told mediapersons, “An agency manned by four persons called Tera Research
based in Oregon, Portland, USA sent a forecast of a fresh tsunami to our
meteorological department at 6.00 am.” This was forwarded by his ministry to
the home ministry without comment.
Questioned
why his ministry did this, Mr Sibal said, “Our duty was to pass on the
information and we did that.”
He
said that he had asked the Hawaii-based Pacific Tsunami Warning Centre to
confirm the forecast. Their answer: “There is no such concern”. ISRO has also
been asked to stay in touch with the centre.
AK
Rastogi of the natural disaster management division under the home ministry
quoted a forecast of a fresh tidal wave from another agency, the Australian
Pacific Tsunami Warning Centre. He said that his surfing of the net had
convinced him that “there is a case for concern”.
The
death toll in the country has risen to 7,368.

IARI to study salinity ofsoil, water in tsunami-hit states
IARI
centenary celebrations begins today

New Delhi, Dec 31
Indian
Agricultural Research Institute (IARI) has decided to send a team of experts to
study soil and water salinity problems in the coastal states affected by the
tsumani tidal wave.
"We
need to find out the salinity problem and identify appropriate saline resistant
seeds for sowing. Our team will also study salinity problems in potable water
and suggest remedies," said IARI director Dr S Nagarajan.
Briefing
mediapersons in the capital on Wednesday, Dr Nagarajan said there is a need for
research on global climate change and effective management of natural
resources. He stressed the need for organic farming, efficient use of energy
and water and encouragement of zero-tillage of soil.
He
said: "It has been field-tested that organic farming of rice and sugarcane
produces the same yield or more than that done through chemical
agriculture."
He
that the prime concern before the country is not that of food security, but of
ensuring nutritional security and management of natural disasters. He said that
deaths due to natural calamity exceed those due to starvation.
"The
IARI will be celebrating a year-long centenary celebration in 2005. The new
focus of IARI will be on nutritional security, organic farming and management
of natural disasters. The centenary celebrations will be formally launched on
January 1, 2005," he said.
Dr
Nagarajan also stressed on crop diversification in lieu of mono-cropping. He
said that disciplines like farm laws, patents and intellectual property rights,
environmental issues will be incorporated in the new curriculum of IARI. In the
coming days, issues like sanitary and phytosanitary measures and other
non-tariff bariers are likely to dominate global trade and hence the country
needs to gear up to meet this challenge, he said.
