Dam can withstand tremors, says SSNL
Dispelling speculations
that the Sardar Samovar Narmada Nigam Limited at Kevadia Colony has become
a potential hazard since the region recorded seismic activity on Sunday,
SSNL officials and dam engineers on Monday asserted that the SSNL dam
structure is infallible unless the SSNL is the epicentre of an earthquake.
Even
as Narmada Bachao Andolan activists raised an hue and cry over the incident,
SSNL officials thoroughly scanned the dam on Monday and confirmed that
the dam structure has not developed even a single fissure. SSNL chief
engineer at the site, P.M. Patel, who checked the dam with one geologist
and two civil engineers said considering the fact that the dam survived
the devastating earthquake of 2001 and that of Sunday, which was of much
low intensity, there is nothing to worry.
He
added that on January 26, 2001, when the massive earthquake rattled the
state, at the dam site, tremors measuring 5.3 on the Richter Scale were
recorded. "Even that could not inflict any damage to the dam structure,"
he said. He asserted that the dam can withstand any tremor up to at least
6.5 on the Richter Scale occurring in a radius outside 10 km below and
16 km away from the site.
While
NBA’s M.K. Sukumar believed that Sunday’s tremors could have
been dam-induced, SSNL dam modeler Nandkumar Kavlanekar claimed, "The
dam has been designed after studying all dams of the world and all lapses
of those dams have been taken into consideration," while SSNL’s
managing director S.K. Mohapatra added that SSNL, which is the world’s
largest concrete dam structure, has been studied thoroughly for seven
years between 1977 and 1985 before a go ahead was given to the state government
to start construction.
The
Dam safety committee, Dam review committee appointed by the World Bank
and Narmada control authority had studied the safety parameters of the
dam before approving design of the dam, SSNL maintained.
