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 19: The Karnataka government has extended the statewide coronavirus shutdown till March 31 as the number of positive cases rose to 14, of whom 11 are those who came in from foreign countries.

In an emergency Cabinet meeting, the state government set up a task force of four ministers to lead the defence against the virus. This core team will have Rs 200 crore to orchestrate the combat.

When chief minister B S Yediyurappa announced the shutdown last week, it was to be in force until March 21, but it was always unlikely that the Covid-19 scare would have waned by then.

Several more restrictions were announced today. Quarantine will be mandatory for all passengers arriving from foreign countries. While schools, colleges and business establishments will continue to be closed, restrictions have been extended to marriages, fairs and social functions as well.

Public entry to Vidhana Soudha, Vikas Soudha and the M.S. Building has been barred till March 31.

While setting up the task force, the government has earmarked Rs 200 crore for the coronavirus campaign. The chief minister said there is no dearth of funds for fighting the virus.

The task force will have deputy chief minister Ashwathnarayana, home minister Basavaraj Bommai, medical education minister Sudhakar, health and family welfare minister B Sreeramulu and chief secretary T M Vijaybhaskar.  Sreeramulu will head the task force.

The task force will monitor coronavirus cases on a daily basis and orchestrate the response of all stakeholders. It will issue a daily bulletin on the epidemic and also run awareness campaigns.

With quarantine now mandatory for passengers coming in foreign countries, community centres, hotels, convention centres, resorts and even PGs will be rented to accommodate the new arrivals.

The compulsory quarantine will be for 15 days.

A quarantine stamp will be imprinted on the right hand of passengers coming in from foreign countries.

Since the Centre has relaxed the rules for using SDRF funds, the state government will draw from it to contain the pandemic; therefore, there will be more funds available to all districts, chief minister B S Yediyurappa said in the Assembly.

In further measures, all passengers and suspected Covid-19 cases will be tracked by their mobile phones.

Primary stage

“We are in the first and second stages of the epidemic. The virus is still at a primary stage and has not spread to community level," medical education minister Sudhakar said in the Assembly.

"It is important that we do not let the epidemic enter the third stage. It is possible if we implement stringent measures. People have responded positively to the state government’s measures and are cooperating with our decisions," Sudhakar said.

French Nobel prize winning scientist Luc Montagnier has sparked a fresh controversy by claiming that the SARS-CoV-2 virus came from a lab, and is the result of an attempt to manufacture a vaccine against the AIDS virus.

In an interview given to French CNews channel and during a podcast by Pourquoi Docteur, professor Montagnier who co-discovered HIV (Human Immunodeficiency Virus) claimed the presence of elements of HIV in the genome of the coronavirus and even elements of the "germ of malaria" are highly suspect, according to a report in Asia Times.

"The Wuhan city laboratory has specialized in these coronaviruses since the early 2000s. They have expertise in this area," he was quoted as saying.

The theory that Covid-19 virus originated in the lab is making rounds for quite some time.

US President Donald Trump last week acknowledged Fox News report that the novel coronavirus may have been accidentally leaked by an intern working at the Wuhan Institute of Virology in China.

The Fox News, in an exclusive report, based on unnamed sources has claimed that though the virus is a naturally occurring strain among bats and not a bioweapon, but it was being studied in Wuhan laboratory.

The initial transmission of the virus was bat-to-human, the news channel said, adding that the "patient zero" worked at the laboratory. The lab employee was accidentally infected before spreading the disease among the common people outside the lab in Wuhan city.

Professor Montagnier was awarded the 2008 Nobel Prize in Medicine for the identification of AIDS virus, with his colleague professor Franeoise Barre-Sinoussi.

His fresh claim on coronavirus, however, received criticism from scientists, including his colleagues.

"Just in case you don't know. Dr Montagnier has been rolling downhill incredibly fast in the last few years. From baselessly defending homeopathy to becoming an antivaxxer. Whatever he says, just don't believe him," tweeted Juan Carlos Gabaldon.

As per a recent Washington Post, two years ago, the US embassy officials in China raised concerns about the insufficient biosafety at the Chinese government's Wuhan Institute of Virology where deadly viruses and infectious diseases are studied.

Though the institute, located quite close to the Wuhan wet market, is China's first biosafety level IV lab, the US state department had warned in 2018 about "serious shortage of appropriately trained technicians and investigators needed to safely operate this high-containment laboratory".
