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 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.

Bengaluru, Jul 29: Karnataka Congress President DK Shivakumar on Tuesday criticised BJP-led Karnataka government for limiting or omitting various topics including chapters on 18th century Mysore ruler Tipu Sultan and his father Hyder Ali.

Speaking to media here at Karnataka Pradesh Congress Committee (KPCC) office, Shivakumar said Congress will not allow BJP government in Karnataka to "divert history".

"Tipu Sultan does not belong to one caste or a class. He is part of the history of this country. BJP government has removed chapters related to him for its political advantage. It is their decision whether they celebrate Tipu Sultan Jayanti or not, but he is part of our history. 

The President of this country Ramnath Kovind came to the Vidhan Sabha and praised Tipu's patriotism during a joint session," Shivakumar said.

"The BJP government has come to power today. Our history should not change. We will not let these people to covert or dilute history. This is the stand of the Congress party. Our experts will study the pros and cons of this decision," he added.

Shivakumar further said many countries around the world have praised the Constitution, Indian history and expressed their willingness to "adapt it".

"But the BJP is trying to curtail this. We need to educate our children. Our team will also study this and we will not let this happen," he said.
The Karnataka government, in a bid to reduce the syllabus for state board schools by 30 per cent, has limited or omitted various topics including chapters on Mysuru rulers Hyder Ali and Tipu Sultan from the class 7 social science textbook.

The reduction in syllabus comes as schools are closed to prevent the spread of coronavirus in the state, and classes have been moved online.
The Department of Public Instruction of the Karnataka government also limited or removed various other topics from the syllabus of class 6 to 10 as they were repeated or can be alternatively taught.

Earlier, the Central Board of Secondary Education (CBSE) had revised the syllabus for the classes IX to XII for the academic session 2020-21 in a "one-time measure" owing to the COVID-19 pandemic.
