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?

Mangaluru, Feb 16: Leaving spectators awestruck, Karnataka's Srinivasa Gowda ran 142.5 meters in 13.62 seconds at traditional buffalo race Kambala, following which people started comparing him to former Jamaican Sprinter Usain Bolt.

Gowda, who is from Mudbidri town, accomplished the feat during a Kambala race in a paddy field in Kadri on February 1.

"People are comparing me to Usain Bolt. He is a world champion, I am only running in a slushy paddy field," said Srinivasa Gowda.

People took to social media and drew a parallel between him and Bolt. Twitterati hailed Gowda and his accomplishment on the muddy grounds.

Kambala is an annual buffalo race held in the southwestern state of Karnataka.

Traditionally, it is sponsored by local Tuluva landlords and households in the coastal districts of Dakshina Kannada and Udupi.

"I'll call Karnataka's Srinivasa Gowda for trials by top SAI Coaches. There's lack of knowledge in masses about the standards of Olympics especially in athletics where ultimate human strength & endurance are surpassed. I'll ensure that no talents in India is left out untested," Union Sports and Youth Affairs Minister Kiren Rijiju tweeted on Saturday.

Bengaluru, Apr 18: Amid fears that people from the unorganised sector are running out of cash to meet their daily expenses, the Karnataka government said there was no data available for such labourers, who can be provided financial assistance under the direct benefit transfer (DBT) scheme.

"The government does not have data of people in the unorganised sector such as drivers, farmers, domestic help and others. If we have to deposit directly into their account, we need data..," State Labour minister A Shivaram Hebbar told reporters.

The minister said a situation borne out of the COVID-19, where the entire nation has been lockdown was never anticipated.

To him, the pandemic has given an opportunity to gather information about the unorganised sector.

"This COVID-19 has taught the department and the workers a lesson that we should be prepared for a situation like this. We have learnt that all the information about labourers should be available with the labour department," Hebbar conceded.

The minister opined that the department should have had the list during the good times but nobody bothered to have it.

"During the good times nobody bothered about it -- neither they (beneficiaries) asked for it, nor we thought of it.," Hebbar said.

Now that the pandemic has struck, the government is focusing only on not letting anyone starve to death.

A three-level preparation has been made -- at the village level, Taluk level and the city level, the minister said.

Village anganwadis have been stuffed with food items to be cooked for the needy, whereas in Taluk level, government hostels have been turned into shelters for the labourers, he said, noting that lakhs of philanthropists in cities have come forward to feed the people from unorganised sector.

"The basic objective of our government is that no one should starve to death. The issue of organised or unorganised sector comes next," he explained.

On the fear of large-scale retrenchment, the minister said notices have been served on all the industries that no one should be expelled from the job.

However, Hebbar underlined that the industrialists today are as much in distress as the workers and his department was taking into account everyone's concern.

A decision will be taken in this connection by the government in the next two days, to provide assistance to small enterprises to keep them afloat.
