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, May 9: The bar owners in Karnataka, while welcoming the state government's decision to allow takeaway sales of liquor, said that the move is not going to benefit them much.

Venkatesh Babu, a Bengaluru-based bar owner said, "We welcome this move, our bar was closed for two months due to coronavirus crisis. We have been facing losses since then."

"The state government has told us to sell our stocks at maximum retail price (MRP). It is difficult for us to manage as the rent is high and we also have to pay salaries," he added.

The owner of Pingara Bar and Restaurant, Shivamogga said, "The government has said that is for parcel only and that too at MRP. There is no benefit to our business. We are only clearing the existing stock. They have given us time till May 17 and are not even giving us fresh stock. We are only allowed to sell what we have already."

Karnataka government in its Friday order allowed restaurants, pubs and bars to sell liquor at retail prices from May 9 till May 17, the day the third phase of lockdown is slated to end.

Earlier, the government had allowed the opening of liquor shops in order to mobilise revenue.

However, bars, pubs, restaurants were ordered to remain closed amid the COVID-19 lockdown.

Jan 14: A day after it moved the Supreme Court against the controversial Citizenship Amendment Act (CAA), the Kerala government on Tuesday said it would continue its fight against the legislation as it "destroys" the secularism and democracy in the country.

The CPI(M)-led government had on Monday moved the apex court challenging the CAA and sought to declare it as 'ultra vires' of the Constitution. State Industries Minister E P Jayarajan told reporters here that the state has moved the apex court and will explore all options to fight the Act.

"The state government will to go to any extent and continue its fight against CAA. This Act destroys democracy in the country. This will only help in implementing the RSS agenda, to drive the nation through a fascist regime, and destroying the secularism and democracy in the country. The RSS and the Sangh Parivar cannot implement this law just by using muscle power," Jayarajan said.

Tourism Minister Kadakampally Surendran tweeted that the state became the first in the country to approach the top court against the Act. "Kerala government files lawsuit against the unconstitutional CAA. Kerala becomes the first state in the country to go to the Supreme Court against CAA.

"Kerala leads the way," he said in the tweet. In a suit filed in the apex court, the Kerala government has sought to declare that the CAA 2019 was "violative" of Article 14 (Equality before law), 21 (Protection of life and personal liberty) and 25 (Freedom of conscience and free profession, practice, and propagation of religion) of the Constitution.

It also claimed that the law was violative of the basic principle of secularism enshrined in it. The state Assembly had on December 31, 2019, passed a unanimous resolution against the CAA and became the first state to do it.
