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.

Kalaburagi, Mar 25: Three coronavirus suspect persons who did not stay home during their mandatory 14-day quarantine period had first information report (FIRs) booked against them in police stations in Kalaburagi town in Karnataka.   

The district administration took this action after it came to know that the three pesons were mingling in the public despite being told to stay home to avoid passing on the coronavirus.

Cases have been booked against them under IPC sections 188 and 271, deputy commissioner B Sharath said.

Stringent action would be taken against them, he said, for not only threatening the health of their family members but society at large.

“The administration will stop at nothing to safeguard public health in this time of emergency,” Sharath said.

People moving around on motorbikes without a proper reason will have their bikes seized. Prohibitory order under Section 144 of CrPC will remain in force until further orders, he said.

New Delhi, Jun 4: The Supreme Court on Wednesday sought response from Prajwal Revanna, the grandson of former Prime Minister HD Deve Gowda, on a plea challenging his election in 2019 from Hassan Lok Sabha constituency as a joint candidate of the Janata Dal Secular and the Congress.

A bench of Chief Justice SA Bobde and Justices AS Bopanna and Hrishiksh Roy issued notice to the returned candidate from the high-profile constituency on an appeal challenging the Karnataka High Court's order by which an election petition against his win was dismissed.

In the proceedings held through video-conferencing, the top court issued notice and tagged the appeal filed by G Devarajegowda for hearing with other similar pending plea filed by the BJP candidate on the issue.

Mr Devarajegowda in the plea said that his election petition was dismissed by the High Court on "procedural irregularities". The plea said that Mr Prajwal had resorted to unfair and corrupt practices and his election should be set aside.

It said the High Court did not consider the fact that by dismissing the election petition, it was running a risk of having a representative in parliament who has not got the maximum number of valid votes.

The petitioner, an advocate by profession, sought a declaration of rival BJP candidate, A Manju, as the winner for having secured the maximum number of valid votes.

A separate appeal was earlier filed by Mr Manju against the High Court order and the top court had already issued notice to the retuned candidate on that.

Mr Manju had challenged the 2019 election of Mr Prajwal on the ground that there was allegedly non-disclosure of assets held by him in his election affidavit.

Mr Prajwal was declared winner with 6,76,606 votes. Mr Manju came first runner-up with 5,35,282 votes.
