GSI has signed MoU with the ministry of earth sciences under which it will be working in collaboration with the Centre for Seismological Research, New Delhi to identify earthquake related activities in prone areas. This will help minimizing human deaths during earthquakes.
"Construction of any building should be based on the underlying geology (rock type or soil type of the area). There are many cities where during construction the builder should ensure that the foundation of the building starts right from below the rock level but unfortunately they rarely consider this as a necessity. The city planning bodies like corporations too don't bother to implement the construction laws strictly," said Kolkata-based GSI director general Sudesh Wadhawan. GSI will soon be connecting its earthquake observatories with the national grid of such broadband seismic observatories run by IMD so that the observations by all observatories are uniform.
Wadhawan was in the city for a national workshop on recent trends in mineral exploration strategies for India, hosted by the central region GSI headquarters. The Bhuj earthquake the GSI chief feels has given a lot of lessons in disaster preparedness and mitigation. Since earthquake cannot be predicted, improving rescue operations and rehabilitation hold the key to minimizing the damage. During quake the movement of soil and water depends on the underlying rock strata and soil type. Those where the foundation penetrates the hard rock, the damage is less. In cities like Mumbai, where most structures are standing on reclaimed land, the damage can be massive, Wadhawan feels.
Also for rescue during earthquake it is necessary that the roads should be at least 12 metre wide so that while clearing operations during rescue the bulldozers have smooth two-way movement facility. But this norm is not followed in all cities.
