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 18: Karnataka Congress president DK Shivakumar on Saturday appealed to Prime Minister Narendra Modi to deposit at least Rs 10,000 in bank accounts of people belonging to the unorganised sector.

"The unorganised sector comprises barbers, dhobi, cooks, carpenters, sweepers, drivers and autorickshaw drivers. Prime Minister Narendra Modi did not mention anything about giving subsistence to these people," Shivakumar, told ANI, referring to the Prime Minister's address earlier this week.

Modi had announced the extension of the ongoing nationwide lockdown till May 3 in order to curb the spread of coronavirus.

"I appeal to Prime Minister Modi to register the members of the unregistered sector under the National Rural Employment Guarantee Act (NREGA) or deposit at least Rs 10,000 to the bank accounts of each of the members of unorganised sector to help them survive the lockdown," he added.

Though the Congress party will continue the central government and state government's fight against coronavirus, he said, both the governments need to help people who are part of the unorganised sector.

"The farmers have told me that due to the lockdown they are ready to sell the vegetables, which once used to be sold at Rs 100 per kg, at even Rs 5 per kg," he said.

Speaking on the suggestions he made to Chief Minister BS Yediyurappa, Shivakumar said, "I requested the Chief Minister to send a team to do a videograph and make an assessment of the on-ground situation. However, till now, no one has gone."
