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?

Mumbai, June 7: As the Maharashtra government has given green signal for outdoor physical activities under 'Mission Begin Again' despite amidst growing cases of covid-19,  thousands of Mumbaikars flocked to Marine Drive for 'morning walks' on Sunday.

People were seen wearing masks as a precaution from the novel coronavirus pandemic, however, from the viral photo, it seems that no social distancing norms were followed what so ever.

"Better call it marne waalon ka drive," said a Twitter user. "Still people have no sense of responsibility," said another Twitter user.

After nearly 80 days of lockdown, Mumbai and other parts of Maharashtra revved back to life on Friday. 

Most markets, market areas, commercial and trading areas - barring malls or market complexes - reopened for business even as Chief Minister Uddhav Thackeray reiterated that "people should tread cautiously while beginning a 'new life' from today".

Meanwhile, of the total 82,968 cases in Maharashtra, Mumbai now accounts for 47,354 cases and 1,577 deaths.

On Saturday, Maharashtra reported 120 deaths, including 58 in Mumbai, due to COVID-19, taking the overall number of fatalities to 2,969, state Health department said.

The recovery rate in the state stands at 45.06 per cent and the fatality rate at 3.57 per cent, an official statement said.

New Delhi, Jun 7: The Karnataka government has asked the railways to make announcements at originating stations that it was compulsory for passengers travelling to the state to register themselves on the ‘Seva Sindhu’ portal through which they can be tracked.

In a letter to Chairman Railway Board on Saturday, Chief Secretary of the state T M Vijay Bhaskar said many passengers are not aware of this mandatory rule of the southern state.

He said thousands of passengers are coming to Karnataka from New Delhi, Bihar, Maharashtra and other states through trains everyday, but most of them are not registered under the Seva Sindhu portal of the Government of Kamataka.

"If passengers are not registered under Seva Sindhu, the state will not be able to track them. Therefore, it is necessary to create awareness among the passengers regarding registration under the portal.

"Hence, it is requested to give instructions to origin railway stations to make announcements that ‘It is compulsory for all passengers travelling to Karnataka to register in Seva Sindhu portal. Otherwise they will not be allowed for home quarantine’, and also to give passengers awareness (about this) at the time of booking tickets,” Bhaskar said in his letter to the national transporter.

Seva Sindhu portal, under the control of the Karnataka government, provides various online services to the citizens of the state.

Currently, this portal is playing an important role in helping those stranded amid the COVID-19 pandemic to fill online registration forms for availing e-passes.

Bengaluru, Jan 3: Karnataka Chief Minister BS Yediyurappa on Friday clarified that Prime Minister Narendra Modi has assured him to consider all the demands made by his government.

"Prime Minister spoke to me personally and assured me of all help and suggested that I visit New Delhi and meet the concerned Ministers and apprise them about the state's problems and pending projects. He also directed me to prepare a detail report on this matter," Yediyurappa said in a statement.

He claimed that a section of media has misinterpreted his speech which was plain and honest towards the development of the state.

"A section of media has attached motive to my speech which was plain and honest in its content. Being in federal set up, there is nothing wrong with placing the facts before the Prime Minister and making submissions," the Chief Minister said.

"As a Chief Minister, I placed our state's problems and need for more funds for developmental activities. I pleaded before the Prime Minister for more funds to the relief work, the scientific and remunerative price for the farm produces, and special fund of Rs 50,000 crore for speeding up of on-going irrigation work. As it was farmers' meet, I felt it worthy and timely to plead the Prime Minister for more funds for all the developmental activities in the state," he said.

Asserting that Prime Minister Narendra Modi is a great visionary and his concern for the poor and farmers is unquestionable, he said: "When the whole world is appreciating his statesmanship and visionary zeal, it is in very bad taste for the media to attribute motives to my speech and relate it to the Prime Minister."

Yediyurappa requested media to show support to his government in the interest of the development of the state.

"I humbly request the electronic and print media not to misinterpret but support the government in the interest of the development of the state and interests of the people. I hope the media will respond to my request," he said.
