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.

"So far, 34 people who came in contact with him have been traced and are kept under strict home isolation by the Telangana health authorities. As of now, all the contacts are stable and under active surveillance by the health teams of the Telangana government," Srinivas said.

He added that the rapid response team of the state is further searching for the persons who might have come in contact with the person who died of COVID-19.

"Telangana health authorities were alerted by the Karnataka government after the 76-year-old man's samples tested positive for coronavirus after his death. The man has visited two hospitals in Hyderabad before he died in Karnataka," Srinivas further said.

The Karnataka man, who had died a few days ago, was confirmed to have tested positive for COVID-19.

Meanwhile, Telangana Health Minister's office said that the lone coronavirus patient from the state has recovered and is going to be discharged from the hospital soon.

Bengaluru, May 13: Former chief minister and senior Congress leader Siddaramaiah on Wednesday called the measures announced by Finance Minister Nirmala Sitharaman as 'disastrous' and said it is 'non-existent' in terms of benefits to poor migrants, labourers, contract employees and farmers.

"The first set of measures announced by @FinMinIndia @nsitharaman, after 8 PM speech by @narendramodi, is disastrous & non-existent in terms of benefits to poor migrants, labourers, contract employees, farmers, etc," Siddaramaiah said in a tweet.

The Congress leader said most of the intended benefits may not reach the end recipient.

This comes a day after Prime Minister Narendra Modi announced a Rs 20 lakh crore special economic package to revive the COVID-19 hit economy.

"The contribution by the government for the schemes announced are mostly notional and less of actuals and the devil lies in the detail," the Congress leader said in another tweet.

After Sitharaman announced support measures for MSMEs, Siddaramaiah said, "The credit infusion to MSMEs may help them clear dues to vendors but it is doubtful if they shall utilise the credit available to pay their labourers & to prevent job cuts. @FinMinIndia should have taken measures to pay part of the salaries to the employees in MSMEs."

Further questioning the Centre on 'ignoring the spending for boosting consumption', Siddaramaiah said, "The government is interested in capital infusion in the form of credits but totally ignorant of the actual spending that needs to be done to boost consumption. How can credit be considered as government spending?"

Siddaramaiah said the next set of measures should benefit the marginalised sections.

"Will be looking forward to next set of measures & I hope it will be something to benefit the marginalised sections. Direct benefits to the poorest sections will help them survive this pandemic. COVID-19 fight should not be another perception battle but a real one," he added in another tweet.

Sitharaman earlier announced Rs 3 lakh crore collateral-free automatic loans for businesses, including MSMEs.

Besides this, she also stated that to provide stressed MSMEs with equity support, the government will facilitate the provision of Rs 20,000 crore as subordinate debt.
