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, Feb 25: A day after Karnataka minister BC Patil felt the need for a law to shoot people who raise pro-Pakistan and anti-India slogans, another BJP MLA on Monday said such people should be shot at sight or exiled to the neighbouring country.

Appachu Ranjan, MLA from Madikeri, said a woman named Amulya had raised Pakistan Zindabad slogan at Bengaluru during a CAA-related meeting.

"People saying Pakistan Zindabad, despite living in our country- eating food and drinking water available here- they should be shot at sight. Or else such people should be exiled to Pakistan, and no one should should show softness towards them and fight cases in their favour," he said at Somwarpet in Kodagu.

Amulya Leona, a woman who raised pro-Pakistan slogans at an anti-Citizenship Amendment Act rally in Bengaluru on Thursday, has been booked for sedition and remanded to judicial custody.

She had raised "Pakistan Zindabad" slogans thrice after the organisers, under the banner of "Save the Constitution", invited her to address the gathering in the presence of All India Majlis-e-Ittehadul Muslimeen (AIMIM) chief Asaduddin Owaisi.

Agriculture minister Patil on Sunday had expressed the need for a legislation to shoot such people, and said he would make a request to the prime minister in this regard. "A law should be brought in the country that who ever raises slogans against India and in favour of Pakistan, they should be shot at sight. Bringing such a law is important," Patil had said.

Mangaluru, May 13: Kannadigas in the United Arab Emirates (UAE) have sought additional flights to return to Karnataka during a video conference with Chief Minister B S Yediyurappa here on Tuesday.

Noting that most of the ex-pats in UAE were from the coastal region, they urged the state government to ensure that most of these flights land in the Mangalore International Airport.

Many Kannadigas in the UAE were left unemployed due to the lockdown. “Many of them do not have the means to return to Karnataka and the state government should aid them,” representatives of various Kannadiga ex-pat groups urged the CM.

Yediyurappa said that the government has made all arrangements to bring back the ex-pats, and assured to fulfil all their demands.
