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 28: With fresh guidelines on the COVID-19 lockdown expected soon, Karnataka Chief Minister B S Yediyurappa on Monday chaired a meeting with key ministers, officials and Deputy Commissioners of districts and discussed about re-starting economic activities in the state, as he took stock about of the pandemic.

"At the video conference with DCs, CM took stock of COVID-19 situation and measures taken to control its spread. Discussions also happened regarding starting of certain economic activities in parts of the state," official sources said. The state government would take any decision in this regard after the Centre issues fresh guidelines or directives, they said, without elaborating.

The meeting came hours after Prime Minister Narendra Modi held a video conferencing with Chief Ministers to discuss the situation arising due to COVID-19 in the country, which is under lockdown since March 25 to contain the pandemic. Only nine chief ministers spoke in the virtual meeting with the Prime Minister and Yediyurappa did not get an opportunity.

A senior Minister, who attended the meeting told PTI, necessary directions regarding the lockdown after May 3, they were likely to come in a couple of days.

"Most of the Chief Ministers wanted the lockdown to continue to contain the spread.... nothing concrete emerged, but we expect the necessary directions will follow in couple of days. This is what we expect after seeing what has happened as a followup to three to four such video conferences in the past," he said.

The Minister said the larger opinion was that the current measures should continue and interstate or inter-district movement should not be allowed. Regarding movement within the districts that are green zone, some decision may be taken soon, he said, adding the Prime Minister also asked states to concentrate on reforms, aimed at attracting investments in the days to come.
