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, Jan 16: Former chief minister Siddaramaiah and other leaders are likely to make the final decision on the name of the next Congress president of Karnataka soon, said party leader Dinesh Gundu Rao on Thursday.

"He (Siddaramaiah) has met all the leaders and I think soon they will make a decision. It has already been delayed, it should not have been delayed so much. I am sure high command will take a decision on this," Rao told reporters here.

Both Siddaramaiah and Gundu Rao had resigned from their posts, Leader of Congress Legislature Party and KPCC president, after the party's drubbing in the bye-elections held for 15 Assembly seats last year.

Bengaluru, Feb 19: Karnataka Chief Minister BS Yediyurappa is facing major dissent within the party and the BJP MLAs held a meeting on Tuesday night at former Chief Minister Jagdish Shettar's residence to discuss the functioning of Yediyurappa-led government, said BJP sources.

According to BJP sources, some of the unhappy BJP leaders and MLAs met last night at Shetter's place and expressed that they are not satisfied with Yediyurappa's leadership.

Last night's meeting shows that party leaders are looking to bring down Yediyurappa from the Chief Minister's post by sending a clear message to the high command that Yediyurappa is incapable of continuing as the CM, said BJP sources.

Other sources in BJP have also asserted that BJP leadership in Karnataka is looking for a "leader" who can lead the party in upcoming elections which is going to be held after three years. At this point of time, it's crucial for BJP to promote second-line leadership.

Meanwhile, a letter is being circulated in the BJP party forum and over social media against Chief Minister Yediyurappa's leadership.

It looks like the same team which is unhappy with Yediyurappa's leadership is trying to convey the same message to their high command. The letter which is being circulated says to be written by one of these leaders' groups against Yediyurappa and his son Vijayendra.

On this, Congress leader Ramalinga Reddy told media, "Maybe the letter is written by the same MLAs because after the expansion of Karnataka cabinet so many leaders from BJP were kept out."

"There is a lot of discontent among BJP MLAs that the ones who have toiled for the party day and night have been neglected from the cabinet expansion. This will definitely result in destabilisation in the government," said Eshwar Khandre, KPCC Working President.

Now party high command needs to look into Karnataka leadership to manage the government in the state.

"Now BJP leadership in Karnataka and Delhi need to look into the matter and need to solve the issue after cabinet expansion," said a BJP leader.
