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, June 22: Even as the covid-19 positive cases are steadily increasing in Karnataka, an expert has claimed that community transmission has begun in Bengaluru and cases could keep rising over the next two months.

“If you look at the natural course of this virus across countries around the world, it is about six months. Now we’re in the fourth month. This will go on for another two months. It also sounds like this is the beginning of the peak. There is also a possibility of the number of cases going up from now on. Even across India, cases are increasing,” says Dr CN Manjunath, director of Sri Jayadeva Institute of Cardiovascular Sciences and Research and State Task Force member.

Besides the increase in number of cases, the virus is advancing silently, stealthily. A lot of people who are testing positive are asymptomatic. In areas like Padarayanapura, Nanjangud and many places in north Karnataka, there have been positive cases who have not had any contact with infected individuals. Some cases recorded in Bengaluru over the last two to three days have not had any contact with Covid-positive people.

Dr Manjunath adds: “We are in community transmission. This will happen because nature is ahead of everything. We have to take all possible precautionary measures at our command. This has to happen. Only then some kind of herd immunity will be developed.”

“We are expanding the guidelines of testing to include a large number of people to be tested. Now, according to the Indian Council for Medical Research (ICMR) guidelines, only symptomatic Influenza like Illness (ILI) or Severe Acute Respiratory Infection (SARI), or a person coming in contact with an infected person are being tested.

But since we have crossed 100 days in Karnataka from the first reported case and we’re getting cases with no travel history or contact with a Covid-positive person, we have to start random testing across the sub-group population. Only then will we understand the burden of the disease and what precautions need to be taken,” he says.

Madikeri, Jan 5: Frequent attacks by Tigers on their cattle in South Kodagu region has left the dairy farmers a worried lot and causing concern for their life.

Several farmers have been rearing cows to supplement their income when low prices of pepper and coffee affect their earnings. At least 13 cows have fallen prey to Tigers in the months of November and December last year.

The Forest Department provides a compensation of Rs 10,000 if a cattle is killed by a tiger or in the attack. The compensation amount is meagre when it comes to the loss incurred by the farmers.

Though the Forest Department has submitted a proposal to increase the compensation amount to the government, no action has been initiated in this regard.

Bengaluru, Jun 24: Former Karnataka Chief Minister and Congress leader Siddaramaiah criticised the current state government rates for COVID-19 treatment in private hospitals and said that the patients must be treated free of charge in all hospitals.

"The state government has fixed rates for treating COVID-19. The current rates are shocking to the people," Siddaramaiah said.
Questioning the state government, he said, "Where can people pay these rates fixed by the government per day? Looking at these rates can be heartbreaking for the people. This raises the question of whether the government is sensitive to people's issues."

"The government must promptly announce free treatment and set up a standard treatment protocol. The government should appoint a panel of experts to continuously monitor whether treatment is being properly administered and create an environment where the public is free from anxiety," Siddaramaiah added.

Karnataka on Tuesday reported 322 fresh COVID-19 positive cases and eight deaths.
According to the state health department, the total number of positive cases has mounted to 9,721 and 150 deaths. So far, 6,004 people have been discharged.
