Mangaluru, May 6: According to an experts survey, it has been found that buildings in Bejai-Balmatta, Attavar -Hampankatta, have not adhered to IS 1893 : 2002, Part 1, which is the criteria for earthquake resistant design of structures, NITK?Civil Engineering Department Professor D Venkat Reddy said.

He was delivering a talk on ‘Earth, oceans and coastal zone management’, organised by Institution of Engineers (India) local centre an Institution of Valuers Mangalore Branch in Mangaluru.

The city falls in seismic zone-3 which means that the quakes of intensity six could occur. The buildings could withstand the earthquakes up to five in the Richter scale. As per Indian Standards on Earthquake Engineering, IS1893:1984 criteria for Earthquake Resistant Design of Structures, the country has been categorised into five seismic zones, based on the seismic intensity. IS is about earthquake resistant design of structures and is applicable to buildings, and other structures such as bridges, dams etc. Earthquakes of magnitude of eight take place in zone five. Nethravathi and Gurupur river basins are tectonically active.

As observed in Nepal, the structural failure of buildings have caused more amount of damage. In contrast, the Pashupathinath Temple is intact, though the building in its surrounding have been badly effected, which is due to the difference in structural pattern.

He further said that seismic waves alone are not responsible . Seismic activities take place round the clock. The earthquakes take place due to the sudden failure of strata. As per an estimation, around one thousand take place across the world everyday and three of them could be serious.

A lineament which is a fault in the underlying geological structure and the constructions on these lineaments such as railway tracks, bridges etc could cause more danger. IIS?has established a network system which records the seismic activities and which can even record 0.1 mm change in the crest of the earth. As per the movement of earth plates, a region will be displaced in a span of hundred years.

Bengaluru, Jan 25: To address the grievances of the Industrialists, over the issue of acquisition of land, the state government have plans to dilute the Land Reforms Act, Chief Minister B S Yediyurappa, said here on Saturday.

Speaking to the media here, on his visit to the World Economic Forum, Davos, recently he said that 'the visit was fruitful and ends with satisfactory note by procuring promises from several Industrial houses to investment in Karnataka'.

Stating that during his five-day stay at Davos, he had met several Industries heads on the sidelines of the summit, and had an interactive meeting with them, Chief Minister said that 'the event had helped us to present our state Karnataka, to convince them about the prevailing industry-friendly environment'.

He said that he had met several heads of global companies, including Arcelor Mittal, Kirloskar, MAHINDRA, Bharat Forge, 2000 Watt, general electrical, Dassault, Dalmia, Lulu Group, Volvo, Nova Nosdik and Domeco.

'The interaction with the corporate heads was encouraging and more investment is expected to flow into Karnataka, in the fields of Mining, Power, Agriculture, Pharma, Education, and Industries.'

Informing that the main grouse expressed by the Industrialists about the bottlenecks being faced in the Land Reforms Act to procure land, he said that 'To make ease of conversion of Agricultural land we have plans to bring amendment and it would be both win-win situation to both Farmers as well as Industries.'

'We have promised them to remove all hurdles, which comes in the way of acquiring land to set up industries, and we have promised to rectify all the administrative problems within a month or two and legal problems in the next couple of months by amending existing laws.'

'We have also plans to present a new Industrial policy in the coming budget and roll out a comprehensive and investor-friendly law', he further said.

Replying to questions, Chief Minister said that 'all those investment proposals which got clearance at the High-Level Clearance Committee would automatically considered as ‘deemed permission’ and start the process of acquisition of land'.
