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.

I'm building a 1story house with slab on load bearing walls instead of the concrete frame structure. Will this be resistant agaianst earthquakes?

Bengaluru, Mar 24: Underlining the seriousness of the coronavirus, which is spreading like wildfire in Karnataka, renowned Heart Surgeon and founder of Narayana Hrudayalaya Dr Devi Shetty on Tuesday predicted that Karnataka alone will have more than 80,000 people affected with the dreaded killer disease COVID-19 if people fail to protect themselves.

He urged the people to cooperate with the Government in preventing its further spread and immediately treat those who are affected.

Dr Shetty, urging the people to remain indoors and not to venture out, said those who are affected should not come out and remain in isolation even in their houses and take all precautions advised by doctors.

He said if 80,000 people in the state were affected, more than 20,000 need to be admitted to Hospital for treatment.

"More than 2000 affected need to be kept under ventilation and it requires more infrastructure in the hospitals," he said.

Bengaluru, Aug 4: Police barricades, yellow banners, walls with a fresh coat of paint and the sounds of bhajan mark parts of Ayodhya as the city awaits its big day Wednesday, when the first brick will be laid for the Ram temple.

Ayodhya is decked up for the bhoomi pujan that will be attended at the Ram Janmabhoomi by 175 people, who figure in a select guest list of seers and politicians topped by Prime Minister Narendra Modi.

Concerned over the spread of coronavirus, the authorities are encouraging others not to come to the temple town, asking them to mark the occasion by celebrating at their homes. The groundbreaking ceremony will be telecast live.

Roads leading to Ayodhya display hoardings with the picture of the proposed Ram temple and of Ram Lalla, the infant Ram, the deity now housed in a makeshift temple.

Around the town’s Hanumangarhi area – named after a well-known temple which Modi will visit on Wednesday – both police sirens and ‘bhajans’ in praise of Ram are heard.

Most of the shops in the locality wear a new look, with their fronts painted in bright yellow. A large number of policemen were deployed there on Tuesday. Some sat in the sweet shops, waiting for their next instructions.

Roads leading into the area are barricaded. Yards of yellow cloth and marigold garlands were being hung on poles.

Even on the day before the event, security checks on vehicles heading to Ayodhya begin from adjoining Barabanki district itself on the Lucknow-Ayodhya road. Policemen take down details, including mobile numbers of the travellers.

Senior Superintendent of Police Deepak Kumar said the focus of the force is on maintaining the Covid-19 protocol.

“So we are not going to allow any outsider to enter Ayodhya city,” he said. Prohibitory orders are also in force and not more than four people will be allowed to gather.

“The markets and shops will remain open but with strict adherence to the Covid protocol,” he said. Outsiders will be stopped from entering the city, but Ayodhya residents will be allowed in if they produce any identification document.

“We are also carrying out random checks on people living in Ayodhya to ensure that no outsiders are staying here,” he said.

The city’s temples and mosques will remain open, but no other religious event – except for the bhoomi pujan – will take place on Wednesday.

Pickets have been set up at sensitive points in the city.

Sub-inspector Ram Chandra Yadav and constables Avnish Kumar and Ankit Chaudhary man the Terhi Bazar Chauraha picket near the Ram Janmabhoomi site.

"We are here for the past some days, and were on duty on the Rakshabandhan day. Duty comes first and only after that come other things in life, like festivals," Yadav said.

Mayank Gupta, who runs a restaurant, was handing out food packets to policemen, his customers.

"For the last two months, I have been providing tiffin to them twice a day. There are around 100 policemen to whom I supply tiffin," Gupta said.
