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, Feb 28: The Liquefied Petroleum Gas penetration in Karnataka is 'absolutely 100 per cent' due to the Prime Minister Ujjwala Yojana, Indian Oil Corporation Karnataka Executive Director D L Pramodh said here on Friday.

In 2014, LPG penetration in the State was only 68 per cent, but after the PMUY, massive number of gas connections were given in the last five years, he said, adding, "It is absolutely 100 per cent today."

"There are 1.6 crore LPG connections out of which around 31.5 lakh -- or around 20 per cent -- come under the PMUY. The 100 per cent LPG penetration in the state will help women in rural areas to make their kitchens smokeless. Against the national average of 2.88 cylinders per family per PMUY annually, the figure is Karnataka 3.4 cylinders in Karnataka," Pramodh told reporters.

On the initiative of blending ethanol with petrol, he said it's 8.6 per cent in Karnataka, the highest comparedto other states, where it's five per cent to 5.5 per cent. The state aims to increase it to 10 per cent. By March 31, the IOC would commission the Rs 10 crore Vapour Recovery System at the Devanagonthi terminal on the city outskirts which would ensure that vapour does not go out in the air when tankers are being filled with fuel. "This is an important measure taken tominimise pollution", he said.

Pramodh also said the IOC has started mobile fuel dispensers, delivering fuels at the doorsteps.

Regarding the IOC's preparedness for Electric Vehicle charging stations, Pramodh said the Ministry of Power has given the company a target to set up 500 charging stations across India in the first phase. The IOC has already signed MoUs with NTPC, Power Grid Corporation Limited, Hyundai Motors, Tech Mahindra and Tata Power in this regard.

In Karnataka, 58 sites have been identified for setting up charging and battery swapping stations.

"Total electric vehicle charging facilities planned by IOC in Karnataka by March 31 is 34, out of which 26 will be EVcharging sites and eight battery swapping stations," Pramodh said.

May 10: Azaan is an integral part of the faith, not the gadget, says veteran writer-lyricist Javed Akhtar, asking that the Islamic call to prayer on loudspeakers should be stopped as it causes "discomfort" to others.

In a tweet on Saturday, Akhtar wondered why the practice was 'halaal' (allowed) when it was, for nearly half a century in the country, considered 'haraam' or forbidden.

"In India for almost 50 years Azaan on the loud speak was Haraam. Then it became Halaal and so halaal that there is no end to it, but there should be an end to it. Azaan is fine but loud speaker does cause of discomfort for others. I hope that atleast this time they will do it themselves (sic)," Akhtar tweeted.

When a user asked his opinion on loudspeakers being used in temples, the 75-year-old writer said everyday use of speakers is a cause of concern.

"Whether it's a temple or a mosque, if you're using loudspeakers during a festival, it's fine. But it shouldn't be used everyday in either temples or mosques.

"For more than thousand years Azaan was given without the loud speaker. Azaan is the integral part of your faith, not this gadget," he replied.

Earlier in March, Akhtar had supported the demand to shut mosques amid the coronavirus outbreak in the country, saying even Kaaba and Medina have been closed due to the pandemic.

He had also appealed to the Muslim community to offer prayers from home in the holy month of Ramzan, which began on April 24.

"I request all the Muslim brothers that now that Ramzan is coming, please say your prayers but make sure that this doesn't cause problems to anyone else. The prayers that you do in the mosque, you can do that at home. According to you, the house, the ground, this all has been made by Him. Then you can do your prayers anywhere," he had said.
