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, Apr 20: Karnataka Chief Minister BS Yediyurappa on Monday came down heavily on Congress legislator BZ Zameer Ahmed Khan over the Padarayanapura vandalism that saw a mob run amok against efforts to quarantine suspected COVID-19 persons late on Sunday evening. 

Khan, who represents the Chamarajpet constituency where Padarayanapura is located, said that authorities should have gone to the area during day time.

“Who is he to say that? What does he have to do with this? Why should we ask him? Should we get his permission to carry out government work? Instead of saying that action should be taken, he is speaking like this. Should we then think that he incited the mob? This is the height of being irresponsible,” Yediyurappa said. 

Following the violence, the police have arrested 54 persons and “five more will be arrested,” Yediyurappa said.

Khan clarified that he did not defend those who indulged in vandalism. “I condemn the incident and action should be taken. I’m not saying officials shouldn’t have gone. My point is that they should’ve gone during the day and by creating awareness beforehand that people need to be quarantined,” he said, adding that the BBMP had identified 57 people to be quarantined in Padarayanapura. 

“People in this area are poor, uneducated and are mostly coolie workers and daily wagers. But whatever happened was wrong,” Khan said. He also pointed out that he was the one who arranged for 80 people to be quarantined in Tipu Nagar. 

Yediyurappa said the Padarayanapura incident was unprecedented. “In the entire state, never had such incidents taken place. Everybody agrees this is unacceptable,” the CM said. “Whoever breaks the law - Hindu, Muslim, Christian or anyone - should face action,” he said.
