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, Jul 27: The Karnataka government on Sunday directed the Director General of Police Praveen Sood to submit a detailed report on the internal security following the United Nations' observation that international terror outfit IS was active in the state.

The UN report stated that Al-Qaeda in the Indian subcontinent, which reportedly has between 150 and 200 members from India, Pakistan, Bangladesh and Myanmar, was reportedly planning attacks in the region.

It also warned that there were 'significant numbers' of ISIS operatives in Karnataka and Kerala. Reacting to the UN report, Home Minister Basavaraj Bommai said the state government has taken a serious note of the report on the activities of IS in the state.

The state government is in touch with the Centre and the neighbouring states to keep a close watch on the activities of suspicious people and their supporters.

"In this context, it has been decided to strengthen the internal security of the state. The Director General of Police has been asked to submit a detailed report," Bommai said in a release.

The state is also keeping a strict vigil on all those entering Bengaluru from other states, the Minister said.
