US-Bangla experts move to find out causes of quakes
Tracing tremors from hidden faults
A group of Bangladeshi and US earth scientists have been working
together to unravel the reasons behind earthquake and carrying out
research to predict its occurrence and location, if possible, for
reducing losses of its aftermath.
The earth scientists of the two countries are now engaged in
unearthing hidden faults and records of shifting rivers by boring 250
wells at different strategic points across the country, Syed Humayun
Akhter, professor of geology department of the Dhaka University told
the New Nation Saturday.
Under a 5-year project launched in January, the scientists are also
installing instruments to pick up tremors that could be a pointer to
hidden faults in a 19-kilometre stretch of sand and mud across the
Brahmaputra delta, he informed.
He further said the scientists have carried out shallow seismic survey
and completed boring of 41 holes across Jamuna from Bogra to
Sherpur. The boring of the remaining 209 holes will be completed in
the next 3 years. The estimated cost for boring each well having a
depth of 100 meters is about Tk30, 000 to 40, 000," he added.
Professor Akhter who is also member of the project, said they want to
build a chronology of earthquakes, and improve hazard maps to know
what had happened earlier and when. Which kind of earthquake can hit
the country and, if possible when, so that we can prepare to reduce
the losses,' the earth scientist said.
Records show that in this river deltaic country, the course of the
Brahmaputra river changed 200 years ago due to an eight plus magnitude
earthquake. We want to identify the geological changes that created
the present landscape, Akhter said.
Previous studies have shown that the region was the site of major
tremors and shifts in plates that caused major Himalayan rivers
Brahmaputra, Ganges and Meghna to shift course suddenly inundating
vast areas, according to the research paper of the project.
"There is a risk of large earthquakes in Bangladesh, The same plate
boundary along the Sumatra-Andaman Islands involved in the 2004
earthquake and tsunami continues to the north into Bangladesh, the
paper said.
"The Chittagong Hill Tracts with their tea plantations, as well as
India's Tripura state in the eastern Himalaya, are part of a zone that
is "squeezed and folded over the main fault and has a potential for a
large earthquake", according to the paper.
Meanwhile, the Geology Department of Dhaka University will hold a
5-day training course on earthquake on the campus from today. A total
of 26 teachers and officials from 26 universities and three government
institutions will participate in the course.
