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Apr 19: A recent government order prohibiting congregations, Ramadan prayers is discriminatory and needs to be withdrawn, JD(S) MLC B M Farookh has demanded.

In a letter to the chief secretary, Farookh pointed out that the order contained certain conditions such as restriction of the use of public address system and delivering Azan in low decibels, which had nothing to do with the prevention of Covid-19 disease.

“These days, Azan includes a call for the community to pray at home and does not offer namaz at mosque. The order also prohibits preparation and distribution of porridge, which has always been taken up in the interest of the poor. The High Court has noted that the relief distribution by NGOs or individuals should not be prevented and the state machinery has to coordinate the same by ensuring social distancing. The ban on distribution of porridge by mosques amounts to discrimination. The order needs to be withdrawn or revisited,” he wrote in his letter.

Further, observing that a religious fair was conducted in Kalaburagi recently, in violation of the government’s social distancing norms, Farookh sought the government to ensure that social distancing norms are enforced with regard to festivals of all communities without discrimination.

Bengaluru, Jan 19: The Karnataka government has given its nod to teach 'Vivekadeepini' slokhas, authored by Adi Shankaracharya, in schools across the state, Chief Minister B S Yediyurappa said on Saturday.

At an event called 'Vivekadeepini Mahasamarpane,' organised by Vedanta Bharati, Yediyurappa said, "It has been noticed that Vivekadeepini, which evolves the mind and illumines a person, has a great effect on students.

Parents and teachers have found a positive change among children who were inspired by Vivekadeepini." "Hence, the government has given its nod to allow teaching Vivekadeepini in the schools in Karnataka," he added.

According to the organisers of the event, around two lakh children from 50 schools participated in the event where they were taught to chant Vivekadeepini, comprising verses for the seekers in the spiritual journey.

Yediyurappa reminded the audience that the Indian culture and civilisation is the oldest and the best, which they should feel proud of. Likening Amit Shah to the first union home minister Sardar Vallabhbhai Patel, he said, "After Sardar Vallabh Bhai Patel if we have seen a union home minister, it is Amit Shah, who has successfully resolved many burning issues of the countries within a few months.

"Shah succeeded in finding a permanent solution to Kashmir issue," Yediyurappa said.

Bengaluru, Jan 13: RSS leader Kalladka Prabhakar Bhat on Monday held a protest march at Ramnagar district’s 
Kapalabetta under the aegis of Hindu Jagran Vedike’s ‘Kanakapura Chalo’ campaign against the construction of the world’s largest Jesus statue there.

Hundreds of protesters of the Vedike staged a protest march in the city starting from the Kanakapura Ayyappaswamy temple.

“We are not here to disturb the peace. We have met each other at the wedding of Sriramulu’s daughter. So you know who I am, DK Shivakumar. How long will you continue with these lies? Is the intention behind the statue of Jesus to solidify your vote bank? Build the statue in America or England, we will not allow it here,” said the RSS leader as the keynote speaker at the rally.
