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?

Shivamogga, Apr 13: Banana farmers in Shivamogga say their crop is rotting and they are incurring huge losses amid lockdown due to COVID-19.

The farmers alleged that although permission has been granted for the sale of agricultural products, with inter-district movements being affected, the local buyers are forcing the farmers to sell their produce at ridiculously low prices.

"Local buyers are asking us to sell bananas at Rs 4-5 per kg which is impossible for us. I do not know what we can do," Vijayendra, a farmer told ANI here.

"We expected the markets to be good during the summer season, I have cultivated bananas in four acres of land. There are thousands of other farmers who cultivate it in smaller hoardings," he added.

The farmer further implored the government to ensure there is an open market and inter-district movement of agricultural produce is allowed to ensure the farmers get the right price.

Vijayendra also said that the bananas have started rotting as they were not being harvested due to the lockdown.

Prime Minister Narendra Modi had last month announced a 21-day lockdown in the entire country effective from March 24 midnight to deal with the spread of coronavirus, saying that "social distancing" is the only option to deal with the disease, which spreads rapidly.

There is also the likelihood that the nationwide lockdown might further be extended even after the completion of the 21-day period on April 14, based on the statements from several chief ministers following a video conference with the Prime Minister held a few days earlier.

Following complaints from several parents and also from private school management associations, Minister for Primary and Secondary Education S Suresh Kumar discussed the issue with officials from the department during a recent meeting and directed them to initiate action against such academies.

Bengaluru, Jun 9: A 24-year-old who wanted to experience the feeling of death lost his life after consuming pesticide — he recorded it all on TikTok — in Koratagere taluk of Tumakuru district on Saturday evening.

Chided by his mother for not earning money, Dhananjaya, a resident of Gouraganahalli, on Saturday evening bought pesticide from a shop and shot a 15-second TikTok video, saying, “I want to experience the feeling of what death would be like. I will try to kill myself.”

Locals rushed Dhananjaya to a nearby hospital where he breathed his last the next morning. Koratagere police registered a case of unnatural death.

According to police, Dhananjaya had in the past rammed his Bajaj Pulsar bike into a tree to ‘experience’ death but had survived with minor injuries. Villagers and family members had advised him to not to take such risks. But he continued to do so as he was obsessed with death and posted his opinion regularly on TikTok, where he had 431 followers.

He tied the knot four months ago and was running an autorickshaw on rent. However, his earnings reduced to zero during the lockdown and he wasn’t mentally stable, claimed villagers.

Investigators said Dhananjaya wanted to scare his mother with his suicide threat and wanted to ‘experience’ death. He consumed poison near a farm but later panicked thinking he would die. However, he was not in a position to ride back home. He called his friend, who visited the spot and shifted him to hospital on Saturday night, police said.
