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.

New Delhi, Jul 3: The aviation regulator DGCA said on Friday it was extending the suspension of scheduled international passenger flights in the country till July 31 but added that some international scheduled services on selected routes may be permitted on a case to case basis.

Scheduled international passenger flights were suspended in India on March 23 due to the coronavirus pandemic.

Modifying its June 26 circular that stated that scheduled international passenger flights will remain suspended till July 15, 2020, the regulator stated on Friday it has decided to extend the deadline to July 31, 2020.

However, international scheduled flights may be allowed on selected routes by the competent authority on a case to case basis,” said the circular by the Directorate General of Civil Aviation (DGCA).

Air India and other private domestic airlines have been operating unscheduled international repatriation flights under the Vande Bharat Mission, which was started on May 6 by the Central government.

India resumed scheduled domestic passenger flights on May 25, after a gap of two months.

Davangere, Jan 15: Karnataka Chief Minister B S Yediyurappa on January 14 threatened to resign when the seer of 'Panchamasali Guru Peetha' warned that the community will leave him, if a BJP MLA from the community is not made the minister during the upcoming cabinet expansion.

The chief minister, who is awaiting the BJP high command's nod to expand his cabinet, amid intense lobbying by the aspirants, wanted the seer Vachanananda swamiji and the 'Panchamasali' community to understand his "situation." Yediyurappa pointed out that he has come to power because of the Congress-JD(S) legislators who rebelled against the then coalition government.

The incident took place when Vachanananda swamiji, while addressing an event at Harihara, near here, said "chief minister, you are a good person, Murugesh Nirani (BJP MLA)has helped you a lot, he has stood by you..if you leave his hands this time, the united Panchamasali community will leave your hands." As the swamiji was making this statement, Yediyurappa, who was seated next to him, rose and threatened to leave the stage.

"If you speak like this I will go away...what are you speaking...kindly pardon me, I will leave, you should not speak like this, if you speak like this I can't work..you can give me suggestions, you cannot threaten me," he said, as the swamiji tried to convince Yediyurappa and asked him to take his seat.

As Yediyurappa acceded to his request, the seer said he was not threatening him but was putting forward the rights of the community. The chief minister, who was visibly upset, was seen talking to Home minister Basavaraj Bommai next to him, who even tried to convince the seer not to continue with the topic. Nirani, a MLA from Bilgi who was Industries minister in the previous Yediyurappa government, was seated on the stage when the incident occurred.

Later addressing the event, Yediyurappa said he was not "selfish" and was even ready to resign.

"Vachanananda swamiji has spoken, through you I request him to understand my situation also. If 17 legislators (Congress-JDS), few even as ministers, had not resigned and stayed away, Yediyurappa could not have occupied this Chief Minister position.

You (swamiji) need not make people raise their hands on any demand, if you tell me, I'm ready to listen to you," he said.

Stating that he was ready to take suggestions from the swamiji on all issues, including on how to run the administration for the next 3 years, Yediyurappa said "I'm ready to bow my head and listen to it, if you don't want I'm even ready to resign and go home, I'm not someone who wants to stick to the chair."

Further noting that if he says that the financial condition of the state is not good it will become headline in papers tomorrow, he said he will have to wait till March for the situation to improve.

"I dont have selfishness, I'm aware that if the Panchamasali-Lingayat community had not stood by me, I could have not sat on this chair (CM)... but kindly understand my situation also," he added.

Yediyurappa is expected to expand his ministry later this month after discussing with BJP national president Amit Shah during his visit to the state on January 18.

As the chief minister has already made it clear that 11 of the disqualified JDS-Congress MLAs who got re-elected in the bypolls on BJP tickets will be made ministers, lobbying has been on within the party for the remaining ministerial berths.

Currently there are 18 Ministers, including the chief minister in the cabinet that has a sanctioned strength of 34.

The cabinet expansion will not be an easy task for the chief minister as he will have to strike a balance by accommodating the victorious disqualified legislators as promised and also make place for the old guard, upset at being "neglected" in the first round of the induction exercise.

He also has to give adequate representation to various castes and regions in his cabinet and also deal with allocation of key portfolios.
