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.

Mandya, Jul 24: Pressing for a total ban on stone mining and quarrying in and around the villages surrounding Krishna Raja Sagar Dam in the District, many organisations have called for Mandya bandh on July 29.

The bandh has been supported by Raitha Sangha, Karunada Sevakara Sanghatane, Auto Drivers Association, Jaya Karnataka, Bharatiya Samvidhana Hitharakshana Vedike, Sugarcane Growers Association, Vokkaligara Seva Trust and Dalita Sangarsh Samiti (Krishnappa faction).

The activists said that the State Government must immediately take steps and permanently ban mining in 20 km radius around KRS as continuous blasting for stones is causing grave danger to the structure.

Bengaluru, Apr 28: Former Chief Minister Siddaramaiah on Tuesday demanded that the Karnataka government announce a "special package" for unorganised sector workers, street vendors and autorickshaw drivers, among others, all daily wagers whose lives are affected by the COVID-19 lockdown. "..a special package needs to be announced to this section of people, this is the demand," Siddaramaiah, who is also Leader of the Opposition in the state assembly, told reporters here.

Alleging that the government has failed to control the spread of coronavirus, he said it is the government's responsibility to take care of the basic needs of those from the unorganised sector, whose lives have been impacted by the lockdown. "It is the duty of the government and they should do it immediately. The package should also be announced. I will hold discussions with leaders of other opposition parties like JD(S), CPI, CPI(M) and BSP in this regard and also on trouble faced by farmers," he added. Alleging discrimination in supply of food packets and ration kits, Siddaramaiah said it was being supplied properly only in constituencies represented by BJP legislators.

"Politics is being played out in supply of food materials to the needy, keeping corporation elections in mind.... We don't want to do politics at this point in time as there is lockdown. If things continue to be the same after the lockdown ends, we will protest on the streets," he said.

Siddaramaiah on Tuesday interacted with representatives of auto rickshaw and cab drivers, street vendors, barbers, unorganised workers organisations, among others, to understand the difficulties faced by them during the lockdown and to know whether help from the government has reached them. He said most of them don't have work and it has become difficult for them to lead their normal lives.

They raised several issues like auto and cab drivers being unable to pay road tax and EMI, he said, adding that he would write a detailed letter to the Chief Minister in this regard The former Chief Minister pointed out that there is about 21 lakh registered organised workers, 1.32 crore lakh unorganised workers and also agriculture labourers in the state.

"Among organised workers only 12.5 of the 21 lakh are said to be getting Rs 2000, that too from the Employees Welfare Fund, while others could not get any money, citing reasons like they have not renewed it," he said.

On the other hand, unorganised sector workers don't get money and were also not getting proper food or ration kits, he alleged Though the labour department claimed that it was supplying one lakh food packets and 1.5 lakh ration kits, as also corporations, there were leakages and it was not reaching the beneficiaries properly, he said.

Udupi, Feb 8: A rare sixth century granite idol of ‘Lajja Gauri’ has been discovered fixed on the road in Barkur village of Udupi district, according to information furnished by Dr. Shivakant Bajpai, Superintending Archaeologist of ASI Bangalore Circle. Lajja Gauri is depicted in nude form and is said to be a fertility symbol. The idol is rare, though very popular among certain cults.

Dr Shivakant Bajpai, who is on a tour of the coastal districts, said that he first came across the image when it went viral on social media. He subsequently traced it to a public road in Barkur, which is an ancient historical town of coastal Karnataka. It was the ancient capital of the Alupa kingdom and a seat of power for several centuries.

“This is a very important idol and hundreds of vehicles pass over it every day. We are rescuing it and I have issued an order to my local in-charge to keep it in safe custody. I have also sent a mail in this regard to the DC and SP of the district,” he said.

The idol is likely to be of 6th or 7th century, though further study is required to confirm a date, Dr. Bajpai said.

Lajja Gauri is a lotus-headed Hindu deity associated with abundance, fertility and sexuality, sometimes euphemistically described as Lajja ("modesty").
