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, Jul 4: Normal life was thrown out of gear as heavy rain under the influence of South East Monsoon started lashing coastal districts of Karnataka including Dakshina Kannada on Saturday.

The heavy rain is likely to continue till July 7, according to the meteorological experts. 

The water level in Netravati river is increasing and district administration has warned the people living in the low lying areas and has asked them to move to safer places.

Owing to lack of storm water drains, water logging of the roads inconvenienced the motorists at KS Rao Road, Pumpwell, Bejai, and other areas. 

The Met department sounded warning for fishermen not to venture into the sea observing that strong winds with speed reaching 50-60 kmph are likely to prevail over Southwest and West Central Arabian Sea till July 5.

Bengaluru, Jan 19: The long-awaited discussions on cabinet expansion finally took place between BJP national president Amit Shah and the state party unit on Saturday, but they produced no result.

Latest indications are that new members will be appointed only after CM BS Yediyurappa returns from Davos, Switzerland, on January 25.

The party held a close-door party meeting at a top hotel in Hubballi. The subject of expanding the cabinet, which currently has 16 vacancies, featured in the talks.

Earlier, Yediyurappa reportedly had a one-on-one with Shah during their 45-minute flight from Bengaluru to Hubballi. He is said to have insisted on accommodating all 11 newly MLAs in the cabinet. These legislators were earlier a part of Congress and JD(S); they contested the December byelections on BJP tickets and won.

This apart, BJP sources said, Yediyurappa and Shah had a brief chat at a private event at Palace Grounds . Separately, Shah, who is the Union home minister, held meetings with Jagadish Shettar, Laxman Savadi and Prahlad Joshi, seeking their views on cabinet expansion.

Shah also wanted to get an idea of what people think about the Yediyurappa government’s performance.

Newly elected MLAs Ramesh Jarkiholi, BC Patil and Srimanth Patil greeted Shah. “We only met him to wish him; we didn’t discuss the cabinet issue. That’s something state BJP members will do,” said Hirekerur legislator BC Patil.

Saturday’s deliberations fail to break the stalemate over the cabinet appointments. There are clear differences in the camp about whether all Congress-JD(S) defectors should be made cabinet members, according to a senior minister attended one such meeting.

Shah reportedly wants only seven to eight newly elected MLAs to be made ministers; the rest of the spots should go to BJP loyalists. Yediyurappa disagrees with this position as he had promised all 13 turncoats places in the cabinet. Two lost in the bypolls.

Shah has now asked Yediyurappa to visit Delhi after returning from Davos to finalise the composition of the cabinet, according to the sources.

Yediyurappa will leave for Davos early on Sunday, while Shah will fly directly to Delhi from Hubballi.
