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?

New Delhi, May 29: Opining that there is no harm in importing ideas from abroad Swadeshi Jagran Manch, an affiliate of Rashtriya Swayamsevak Sangh, has suggested that India should take a cue from Pakistan and turn the “locust threat” into “chicken feed.

In an interview, Ashwani Mahajan, national co-convener of Swadeshi Jagran Manch (SJM) said: “I saw an article which shows that Pakistan has turned the locust threat into an opportunity by converting it into chicken feed”

“If there is a good idea originating from anywhere, we should be open to exploring such ideas. We should adopt good ideas. There is no harm in that,” he added.

He also shared the article on Twitter and wrote: “Pakistan turns locust threat into chicken feed. Need to understand the idea and replicate it in India.”

The article stated “an innovative pilot project in Pakistan’s Okara district offers a sustainable solution in which farmers earn money by trapping locusts that are turned into high-protein chicken feed by animal feed mills”.

“It was the brainchild of Muhammad Khurshid, a civil servant in the Ministry of National Food Security and Research, and Johar Ali, a bio-technologist from the Pakistan Agricultural Research Council,” according to the article.

Both Pakistan and India have been hit by locust attacks. These are desert locusts, which is one of the 12 species of short-horned grasshoppers. Swarms can comprise billions and travel up to 130 km in a day.

India has been battling the locust attacks with moderate success since December. However, the onset of monsoon could bring more trouble.

Bengaluru, Jun 16: Continuing easing of restrictions under 'unlock-1,' the Karnataka government has allowed shooting and production of films and television programmes in the state.

In a clarification, Principal Secretary Revenue N Manjunath Prasad said, shooting and production of all films and television programmes that were stopped in between due to lockdown can be allowed.

It is also allowed to continue with the post-production activities of film and television programmes after completing the shooting, it said.

The permission is conditional as it is subjected to adhering of the national directives issued in connection with the COVID-19 pandemic, and standard operating procedures prescribed by the Department of Information and Public Relations.

The clarification said permission can be given as film and television shooting and production activities are not banned under guidelines issued by the centre and the state government recently.
