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?

Mangaluru, Jun 12: A huge crowd gathered for the grand opening of the newly built 175-metre-long two-lane bridge across Phalguni River on National Highway 169 near Gurupura on the outskirts of the city today.

Even as the photos of the bridge inauguration ceremony went viral on social media, netizens took the elected representatives and the district administration to task for flouting safety norms at a time when the coronavirus cases are continuing to mount in coastal Karnataka.

The bridge was completed in a record time of 15 months. Dakshina Kannada MP and State BJP President Nalin Kumar Kateel and district in-charge Minister Kota Srinivas Poojari inaugurated the bridge in the presence of Mangaluru City North MLA Y. Bharath Shetty and others.

The bridge has come as a breather to thousands of travellers between Mangaluru-Moodbidri-Karkala on the busy NH. The age-old steel bridge had become dilapidated and was a cause for concern for road users. The highway is also under the process of getting widened to four lanes.

The bridge was constructed at an estimated cost of Rs 30 crore by contractor Sudhakar Shetty of Mugrodi Construction. Work started in February last and the contractor had time till February next.

While the two-lane carriageway is 16 metres wide, the bridge has 2.5-metre-wide pedestrian paths on both the sides. New approach roads of 500 metres each were also part of the project.

New Delhi, Feb 3: Congress leader BK Hariprasad on Monday condemned BJP MP Anantkumar Hegde's remark on Mahatma Gandhi and termed him as "son" of Nathuram Godse, the assassin of the freedom fighter.

"Only sons of Nathuram Godse can make such comments on Mahatma Gandhi," Hariprasad said.

Hedge had attacked Mahatma Gandhi by calling the freedom struggle led by him a "drama" and also questioned as to how "such people" come to be called 'Mahatma' in India.

"None of these so-called leaders were beaten up by the cops even once. Their independence movement was one big drama. It was staged by these leaders with the approval of the British. It was not a genuine fight. It was an adjustment freedom struggle," he had said.

The Trinamool Congress also lent its support to Congress as its leader Saugata Roy said people like Anant Hegde cause shame to the nation. "We are a supporter of Gandhi and they (BJP) are Nathuram Godse supporters. People of this country should see how BJP MPs are as they insult father of the nation," he added.

BJP leaders too found it difficult to defend Hegde on the controversial remarks.

Senior leader Jagdambika pal was cautious in his defence and said, "The whole world knows about Gandhi and it may be his personal opinion."

Whereas senior BJP leaders avoid commenting on Hegde, Union Minister Ashwani Choubey said that Hegde should not have made the comment and added that Gandhi is a well-respected figure in the nation.

Another BJP MP from Haryana Sanjay Bhatia also tried to shy away from making a direct comment and instead said," Congress did not implement what Gandhi preached. It is Prime Minister Narendra Modi who implemented Gandhi's teachings in letter and spirit."
