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 11: Karnataka Congress chief D K Shivakumar on Saturda said that he was hopeful that the Karnataka Chief Minister would take stern action against BJP MLA M Jayaram--who was on Friday seen celebrating his birthday with several villagers in Gubbi taluk in Tumkur, in violation of social isolation measures and nationwide lockdown to fight the coronavirus outbreak.

"I am sure that the Chief Minister will take action on all these types of activities. We have already petitioned the DGP. Suo moto case should be registered immediately," the Karnataka Congress Chief told media.

Speaking about the video conference meeting that Congress President Sonia Gandhi held with all Pradesh Congress Committee (PCC) presidents via video conference, he said: "She has given us directions that the party has to play its own role. She said that the party needs to be very active, apart from the government."

With regards to the farmer's struggles due to the national lockdown, the Karnataka Congress Chief said that the farmers are in a 'very grim situation'. "I appeal to all the people of Karnataka that we should go to the fields and discuss with farmers and buy the materials. Let us purchase their fruits and vegetables and distribute them at the village level."

Bengaluru, Jan 24: Karnataka Chief Minister BS Yediyurappa on Friday said the much-delayed Cabinet expansion will take place in the next three days.

At the Kempegowda International Airport, after his arrival from Davos, he informed that he would discuss the matter with Union Home Minister Amit Shah to take a final decision on the distribution of important portfolios.

Deputy CM Ashwanath Narayna, Home Minister Basavaraj Bommai and others received the Chief Minister at the airport. The issue of Cabinet expansion was kept in abeyance, ever since the spectacular victory of 12 Assembly seats for BJP, for which the by-elections were held recently. The bypolls were necessitated, following the resignation of about 17 sitting Congress and JD (S) MLAs, which resulted in the collapse of the JDS-Congress coalition government in the state.

BJP had reportedly lured the Congress and JD (S) MLAs into their camp, after promising them to give party ticket to contest the elections, as well as ministerial berths. The Chief Minister had kept as many as 16 Cabinet berths, along with plum portfolios, vacant, after forming the BJP government, with the support of the deserted Congress and JD (S) MLAs, in July last. However, the issue of Cabinet expansion had postponed on one reason or the other, as Yediyurappa was struggling to keep the promise he had made to the former Congress and the JDS MLAs, on whose sacrifice the BJP came back to power.

With the strong demand for ministerial berths within the loyal BJP MLAs, the BJP high command had reportedly advised Yediyurappa to accommodate only a few of the turncoat MLAs and strike balance between the groups.

However, Yediyurappa, who had assured the Congress and JD (S) MLAs of giving them Cabinet berths, had been in dilemma ever since and found it tough to convince the party's Central leaders.

According to party sources, the Chief Minister is not only facing problems over the expansion of his Cabinet, but is also worried over the demand for creation of more number of Deputy Chief Ministers, adding to the present list of three.
