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?

Thiruvananthapuram, Mar 20: One more person tested positive for coronavirus on Thursday, taking the total number of cases to 25, as the Left government announced a Rs 20,000 crore financial package to tide over the present crisis being faced by the southern state in the wake of the virus outbreak.

The multi-crore special package includes Rs 500 crore health package, Rs 2,000 crore loans and free ration.

The man who tested positive had returned from Dubai and hailed from the northern Kasaragod district, Chief Minister Pinarayi Vijayan told reporters after a COVID-19 review meeting.

He said 65 people were hospitalised on Thursday.

"At least 31,173 people are under surveillance, of whom 237 are in observation in hospitals across the state" he said.

Detailing the financial package, Vijayan said loans worth Rs 2,000 crore would be made available to needy families through all-women network 'Kudumbashree' during April-May.

Rural employment guarantee programmes worth Rs 1,000 crore each will be implemented in April-May, he said.

Social security pension of Rs 1,320 crore, to be given in April, would be distributed this month, he said, adding that 50 lakh people are benefited through the pension scheme.

Those belonging to the below poverty line (BPL) and Anthyodaya, who are not receiving social security pension, would be given Rs 1,000 each, for which Rs 100 crore would be earmarked.

Cutting across APL and BPL families, 10 kg free ration would be given and Rs 100 crore would be set apart for the purpose, he said.

A string of 1,000 low-cost hotels, providing food at Rs 20, would be opened across the state next month, the chief minister added.

The 'fitness' charges of autorickshaws and taxis and one month tax of stage and contract carriages would be waived, Vijayan said.

Bengaluru, Apr 5: Opening of Karnataka's borders to Kerala at this point in time will be like "embracing death," chief minister B S Yediyurappa said on Saturday making clear his government's stand not opening the state border.

The chief minister repeatedly said that for his government interest of the people of the state was supreme.

Yediyurappa made his stand clear in a letter to former prime minister and JD(S) patriarch H D Deve Gowda.

Gowda had recently written to the chief minister on March 31 seeking relaxation of the border restrictions on "humanitarian" grounds.

He had also written to Kerala chief minister Pinarayi Vijayan expressing his anguish against Karnataka authorities for imposing restriction and promising to raise the matter with prime minister Narendra Modi.

Stating the decision to close the border was not sudden, Yediyurappa said, it was a conscious decision after analysing the health situation in the area following the spread of COVID-19.

The chief minister cited the Indian Medical Association, Mangaluru branch data regarding the spread of Covid-19 in Kasargod of Kerala and surrounding areas which was alarming.

Noting that the region has nearly 106 positive coronaviruscases, he said, "this is the region with most number of infections in the country."

If this restriction is removed, it puts the health of the people of Karnataka in to risk and create a situation of "embracing death", so we will not be able to open the border, Yediyurappa said.

He also clarified that there was no prejudice behind his government's decision, and the interest of the people of the state was of utmost importance.

"...There is also no political maliciousness. We want to have good and brotherly relationship with neighbouring states," he said, adding that opening the border will open a pandora's box that will be disastrous for the state.

Yediyurappa also thanked opposition parties for their support to his government in its fight against COVID-19.
