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.

Bengaluru, Feb 29: The BJP leaders in Karnataka rallied behind Vijayapura MLA Basanagouda Patil Yatnal amid a controversy over his remarks that centenarian freedom fighter HS Doreswamy was a "Pakistani agent."

The saffron party leaders have extended support to Yatnal, days after he called Doreswamy a "fake freedom fighter" who behaves like a "Pakistani agent".

Yatnal made the comments at a press conference on February 25 while reacting to a query on a public meeting organised by the Congress titled 'Save the Constitution'.

"There are many fake freedom fighters. There is one in Bengaluru. Now we have to say what Doreswamy is. Where is that old man? He behaves like a Pakistan agent," Patil had said.

"Doreswamy is an elderly person and senior to all. He had participated in various agitations. He should also see what to talk and who will be hurt with those statements. We have all seen what he said about Prime Minister Narendra Modi," Primary and Secondary Education Minister S Suresh Kumar told reporters in Kodagu on Saturday reacting to Yatnal's outburst against Doreswamy.

Noting that the statements were made in bitter taste, Kumar said, "If you speak unpleasant (things), you will hear unpleasant."

Bellary City MLA G Somashekara Reddy too backed Yatnal saying that the his statement was appropriate. "There is nothing wrong in his statement. It is absolutely correct. I support him. It is not just okay to be a freedom fighter, but he should be a 'Deshbhakt' (patriot) too, who respects the unity and integrity of the nation."

On Friday, another BJP Minister KS Eshwarappa slammed Doreswamy alleging that he had visited Amulya Leona's residence and shared a good relationship with her family.

Leona had raised 'Pakistan Zindabad' slogans at an anti-CAA event here on February 21, taking everybody present by shock and dismay.

"We respect Doreswamy but he dances to the tune of Congress and supports whatever their leaders say," Eshwarappa said.
