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, Feb 17: Days after 10 MLAs were inducted in the Cabinet, Chief Minister B S Yediyurappa is likely to expand his Cabinet again as some BJP MLAs are unhappy, said BJP sources.

Several leaders including Umesh Katti, CP Yogeshwar, Raju Gowda and MP Renukacharya are miffed over the recent cabinet expansion, claim sources.

On February 6, ST Somashekar, Ramesh Laxmanrao Jarkiholi, Anand Singh, K Sudhakar, BA (Byrathi) Basavaraj, Arabail Hebbar Shivaram, Hasavanagowda C Patil, K Gopalaiah, Narayana Gowda and Shrimant Balasaheb Patil took oath as ministers.

It should be noted that many MLAs had won the by-polls on a Bharatiya Janata Party (BJP) ticket in December last year after switching loyalties from the Janata Dal (Secular) (JDS) and Congress.

In the December 5 by-polls held in 15 Assembly constituencies, the BJP had won 12, while Congress managed to bag only two. One seat was won by an Independent candidate while the JDS drew a blank.

Feb 26: The Tamil Nadu government on Tuesday claimed that it prevented Karnataka from discussing the contentious Mekedatu reservoir issue at the Cauvery Water Management Authority (CWMA) meeting held in New Delhi.

Besides the representatives of Tamil Nadu and Karnataka at the fifth meeting of CWMA, presided over by Central Water Commission Chairman R K Jain, officials of Kerala and Puducherry also participated.

CWMA member and TN PWD Secretary K Manivasan told reporters after the meeting that the state government prevented Karnataka from discussing the dam issue by pointing out the pending petitions in the Supreme Court against the project filed by the E Palaniswami government.

"We have told participants of the meeting that Mekedatu reservoir will be against the interests of Tamil Nadu and its farmers. Our consistent stand is that it should not be built at any cost. Finally the issue was not discussed in the meeting," Manivasan said.

The Mekedatu reservoir is proposed to be constructed by Karnataka across Cauvery river near Mekedatu, about 110 km from Bengaluru, in Kanakapura taluk.

It was first proposed along with Shivanasamudra hydro power project at Shimsa in 2003 with an intention to use the water for a hydro power station and supply drinking water to Bengaluru city. It was designed to store 67 tmc feet of water.

While Tamil Nadu is claiming that the construction of a balancing reservoir will disturb Cauvery water flow to the state affecting irrigation, Karnataka says the project is basically designed to take care of the drinking water needs of Bengaluru after releasing water to Tamil Nadu as per the quantum specified by the Cauvery water disputes tribunal.

Bengaluru, Apr 10: A Karnataka BJP MP's daughter who recovered from COVID-19 has said she did yoga and ''pranayama'' while in hospital quarantine and these were key to defeating the pandemic.

"I was there in the hospital for 14 days. I used to do Yoga and Pranayama. It helps a lot. Everyone should start doing it now," said Ashwini GS, daughter of Davangere MP GM Siddeshwara.

In a video message that went viral on Thursday, she said coronavirus was "not something to be feared and yoga, pranayama and a strong mental state are the key to defeat the pandemic."

Ms Ashwini tested positive for COVID-19 after she had returned from Guyana last month. She was admitted to the SS Hospital in Davangere where she was quarantined for 14 days.

"Throughout my stay in the hospital I did not have any symptom of coronavirus. I neither sneezed, nor coughed or had a running nose. There was no fever either," Ms Ashwini said.

However, she kept herself physically and mentally fit.

"Maintain social distancing, be aware of dos and don'ts and stay safe," the MP's daughter said.

The AYUSH Ministry's protocol has outlined measures to build a strong immune system and it included consuming warm water, practising yogasana, pranayama and meditation for 30 minutes every day.
