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, Apr 7: The Karnataka Government indicated today that it is too early to take a call now on lifting the nation-wide lockdown but said it’s in favour of its extension in COVID-19 hotspots in the country by at least an additional two weeks.

“We need to see for another few days before taking final call,” Medical Education Minister Sudhakar K, who is in-charge of all matters related to COVID-19, told news agency Press Trust of India when asked if the State is in favour of the rollback after the 21-day period ends on April 14.

The minister opined that the decision on its withdrawal should be based on the COVID-19 pandemic situation at the time in terms of number of cases and response to the outbreak.

When the lockdown is lifted, it has to be in a staggered and phased manner, and not at one go, Mr Sudhakar stressed.

“Where there are red alerts and zones, those zones, in my opinion, should continue to be in a lockdown situation at least for two weeks…till this month-end, I will request them (the Centre) to do this,” he said.

The Telananga Chief Minister K Chandrasekhar Rao on Monday appealed to the Prime Minister Narendra Modi to extend the 21-day national lockdown imposed to contain COVID-19 outbreak beyond April 14, saying it was essential to save lives.

Mr Sudhakar said the Karnataka government is facing financial challenges because of drastic fall in revenues due to the lockdown, adding, it would take “tough decisions” to cut expenditure.

The Finance Department is in the process of evaluating the state’s fiscal position.

“Finance department is gathering information…what is the need now, what should be the overall expenditure, how much we can save; financial support for unorganised and organised sector, along with stimulus to other sectors, we have to see where we stand financially,” the minister said.

“Based on that, we have to take certain steps for sure because after all the government runs on the exchequer money. Once the exchequer is stopped because of lockdown, we are not getting GST, no motor vehicle tax. No tax money is coming.”

Government also has to run right? he said.

He said commitment and obligations with regard to paying interest on loans taken at the national and international level would have to be met.

“So, there are some financial constraints, and financial challenges before the government. The Government will take tough decisions only after studying the entire finance (position of the State).”

The Telangana government last week announced pay cut for government employees.

The Union Cabinet on Monday approved a 30 per cent cut in salaries of all Members of Parliament and a two-year suspension of the MP Local Area Development (MPLAD) scheme.
