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, Jun 7: An eminent scientist on Sunday suggested a shift system in schools to prevent spread of the coronavirus and continuing with online classes with focus on project-based learning in a big way to promote creativity.

Former Director General of the Defence Research and Development Organisation (DRDO) V K Saraswat supported the idea of online teaching in the absence of regular classes in view of closure of schools due to the COVID-19 pandemic.

But, he said it should be organised in far better and more interactive ways so that delivery of knowledge can be better. The NITI Aayog member stressed the need for schools to have a strategy when they reopen keeping in mind the safety of students.

May be they will have to organise shifts so that within the same space they can handle the students; May be they will have to employ more teachers, and they can run two shifts. "May be half the strength in a class can come in the morning and others in the afternoon.

Or students of first to sixth standard can come in the morning and seventh to tenth can come in the afternoon, Saraswat told PTI. Reopening strategy will have to be worked out by the education department, added the former Chief Scientific Advisor to the Defence Minister.

Along with normal classes, online education should be continued as a regular system in future, and promoted in a big way because that is the way technology is going to help delivery of knowledge, he added. Saraswat also raised the pitch for reforms in the education sector, saying India is facing the problem of rote learning.

Rote learning has to give way for more project-based teaching, he underlined. Children should be made to work on projects at home and that can be done online. That will also support the changeover from rote learning to creative learning.

I personally believe the education delivery system -- primary, secondary and college levels -- has to be completely changed because creativity in India is less and creativity would come only if we replace rote learning with project-based learning, Saraswat said.

On some academics holding the view that the marks-based model is killing the education system in India as it does not promote creativity, he said evaluation of any outcome is important. Even when we perform in our normal way, evaluation cannot be replaced.

Otherwise, you cant find out how much you have succeeded in delivery. Certainly evaluation cannot be dispensed with. He did not agree with some experts, who favoured a single, uniform system for school education in India by dispensing with CBSE, ICSE and state boards. I am not for normalising everything in life.

I personally believe variety should be there. This concept of one kind of a system is okay for a Communist society, society which was trying to drive everybody like a herd, he said.

Creativity comes with variety, and there is nothing wrong in having different kinds of education system, but one thing which is important is we have to integrate vocational training as part of the education curriculum," Saraswat said. Vocational part cannot be kept away from the education system, he added.

Bengaluru, May 2: Former chief minister and Congress leader Siddaramaiah have urged the state government to arrange free-transport facilities to those stranded labourers and their family members to return their native places.

In a statement issued here on Friday, the former chief minister criticised the State Government for having decided to collect bur fare from them, ''three-times more than the regular fare''.

Stating that the migrant labourers, who had been stranded ever since lockdown had been clamped in the entire country are not in a position to pay for their travel, Siddaramaiah urged the state government to treat them with human face.

Bengaluru, Jan 2: Former chief ministers of Karnataka Siddaramaiah and H D Kumaraswamy on Thursday launched a scathing attack on Prime Minister Narendra Modi as he embarked on a two-day visit to the state attend events in Tumakuru and Bengaluru. In a series of tweets, the Congress and the JD(S) leaders took a dig at Modi for his alleged failure on various fronts.

"You did not visit Karnataka when it was devastated by floods, you did not visit Karnataka when our farmers cried for help, but all of a sudden, when you want to launch your political propaganda, you remember the innocent people of Karnataka. Wah Modi Wah!!" Siddaramaiah tweeted.

In another tweet, the Congress leader claimed Karnataka is starved of Central government funds as there were no adequate flood relief, no GST revenue loss compensation and there was a delay in the transfer of grant-in-aid.

He further said, "Before attempting to fool our people, let the people of Karnataka know when they will get their due share!" He also sought to know from Modi why the 25 MPs from Karnataka have 'turned off' their engines.

"With 25 MPs from BJP and a state government with BJP, people hoped for a double engine. Instead, all BJP representatives have turned off their engines and have become sycophants to play a tune to your idiosyncrasies. Why, are they scared of you?" Siddaramaiah said.

Seeking an explanation on various incomplete projects, the Congress leader said, "Mr Narendra Modi, people are fed up of your lies and double-edged sword comments. We want your answer today about long-standing questions on: Kalasa Banduri Yojana, Belagavi border issue, exams in Kannada, Tulu & Kodava in 8th schedule, the list goes on." Kumaraswamy too minced no words as he went on the offensive against the Centre.

In his tweets quoting newspaper reports, he said Karnataka's coffer has dried up, financial position is in doldrums and the revenue has plummeted.

"What's the reason (behind poor economic situation)? The poor economic policies of the Centre. After swallowing the GDP and development of the country, the wrong policies have affected the state too," alleged Kumaraswamy.

Quoting reports, Kumaraswamy said the Centre has denied the state's share of revenue.

"About 5.44 per cent of state's share is yet to come from the Centre. This is step-motherly attitude of the Centre towards the state," Kumaraswamy tweeted.
