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.

"At the video conference with DCs, CM took stock of COVID-19 situation and measures taken to control its spread. Discussions also happened regarding starting of certain economic activities in parts of the state," official sources said. The state government would take any decision in this regard after the Centre issues fresh guidelines or directives, they said, without elaborating.

The meeting came hours after Prime Minister Narendra Modi held a video conferencing with Chief Ministers to discuss the situation arising due to COVID-19 in the country, which is under lockdown since March 25 to contain the pandemic. Only nine chief ministers spoke in the virtual meeting with the Prime Minister and Yediyurappa did not get an opportunity.

A senior Minister, who attended the meeting told PTI, necessary directions regarding the lockdown after May 3, they were likely to come in a couple of days.

"Most of the Chief Ministers wanted the lockdown to continue to contain the spread.... nothing concrete emerged, but we expect the necessary directions will follow in couple of days. This is what we expect after seeing what has happened as a followup to three to four such video conferences in the past," he said.

The Minister said the larger opinion was that the current measures should continue and interstate or inter-district movement should not be allowed. Regarding movement within the districts that are green zone, some decision may be taken soon, he said, adding the Prime Minister also asked states to concentrate on reforms, aimed at attracting investments in the days to come.

Bengaluru, Jun 29: The results of second pre-university and the Secondary School Leaving Certificate examination results will be out by July last week and August first week, Karnataka Primary and Secondary Education Minister S Suresh Kumar said on Monday.

Instead of giving general promotion to the 10th and 12th standard students as the Central Board of Secondary Education and other states have done, the Karnataka government decided to hold the examination defying the coronavirus scare.

"We are trying to get the SSLC results out by the first week of August.The PUC results will be out in the last week of July," the minister told reporters in Bengaluru.

Amid reports of schools increasing the school fees ignoring the government's direction, the minister said he has got reports that 1,150 schools have increased their fees of which action has been taken against 450 schools.

"We have directed all the schools not to increase the fees in view of the coronavirus scare.

It is a peculiar year.Humanity says no one should increase fees.

We have set up a helpline. If we come across such practices, we will initiate action," Kumar said.

He said an officer has been entrusted to look into the complaints against schools.

Speaking about online classes for kindergarten students, the minister said such classes are not allowed.

The schools can hold talks with parents twice a week about grooming their children.

Kumar said a decision on opening kindergarten schools will be taken after July 5.

He, however, conceded that most parents are unwilling to send their children to school.

The government is gathering the opinion of parents based on which a decision would be taken, he added.

Regarding education to students from Class one to Class 10, Kumar said the Centre has given guidelines, which will be followed.

The state has formed an expert committee to recommend guidelines on education to children from Class I to Class six.

"Once the committee report comes, we will formulate regulations," Kumar added.
