Mangaluru prone to earthquakes, says survey

May 6, 2015

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.

I'm building a 1story house with slab on load bearing walls instead of the concrete frame structure. Will this be resistant agaianst earthquakes?

Bengaluru, Apr 13: Eminent scientist and NITI Aayog member V K Saraswat said on Monday the number of COVID- 19 cases is not going to go beyond what's being reported daily in India as he maintained that the country is in the process of flattening the curve.

The former Scientific Adviser to Defence Minister said the coronavirus positive cases have seen a sharper rise in the last four-five days because of increase in the number of testing.

"It's a good sign; all those asymptomatic cases lying hidden they are also coming out," Saraswat told PTI. "We certainly had a catalytic factor which was basically this (Nizamuddin) Markaz problem which has actually created clusters at different places and that has also been one of the factors for the kind of rise that has taken place."

But he said India is in a much better shape compared to other nations in the battle against COVID-19. "I can only say that the rate is not going to go beyond what has been going on now, may be 700 to 800 cases per day. So, we are in the process of flattening the curve."

The government's decision to declare nation-wide lockdown has paid dividends, Saraswat, a former chief of the Defence Research and Development Organisation, said.

Noting that India has seen a series of virus attacks in the last 15-20 years including Chikungunya and Dengue, he said the emphasis now should be on more and more R & D to find vaccines in advance.

Bengaluru, Jan 16: Former chief minister Siddaramaiah and other leaders are likely to make the final decision on the name of the next Congress president of Karnataka soon, said party leader Dinesh Gundu Rao on Thursday.

"He (Siddaramaiah) has met all the leaders and I think soon they will make a decision. It has already been delayed, it should not have been delayed so much. I am sure high command will take a decision on this," Rao told reporters here.

Both Siddaramaiah and Gundu Rao had resigned from their posts, Leader of Congress Legislature Party and KPCC president, after the party's drubbing in the bye-elections held for 15 Assembly seats last year.
