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, May 29: The hotel industry is one of the worst-hit industries due to lockdown, along with the tourism industry. Bengaluru's hotel industry has incurred a loss of around Rs 1200 crore during the lockdown period however, the hotels here are likely to open in June if the State government issues guidelines for the resumption of their services.

Speaking to media, PC Rao, President, Bangalore Hotelier's Association said, "It's not only the loss of business, but we have lost the customer base as well. 
We don't expect any good future for the next six months. There will be a slow down in the business even after opening."

"We have requested our CM to give first preference to the hotels. We are going to restart our business in June if granted permission. Around 10 per cent of the hotels cannot open at all. They are in the stage of merging or closing down position. Few hotels may open after five or six months," he added.

He continued saying that many hotels are for sale but there are no buyers. There are around 21,000 restaurants in Bangalore, 3500 hotels with rooms and restaurant which has an average turnover of Rs 20 crores per day, Rao informed.

"We expect losses of around Rs 1200 crores in these two months. We are giving special online training to all the hoteliers and to our managers particularly to deal with the COVID-19 situation, including how to deal with the guests, employees, how to start the hotel services. 

Each and every manager has already been trained and we are still continuing it. We will conduct face to face meeting as well and brief the managers," said Rao.

The euphoria over the claim that around 3,000 tonnes of gold reserves, worth Rs 12 trillion, have been discovered in Uttar Pradesh’s Sonbhadra district could not last even 24 hours, with the Geological Survey of India (GSI) clarifying on Saturday there had been no such discovery.

The GSI, headquartered in Kolkata, rebutted the claims of the Uttar Pradesh Directorate of Geology and Mining (UPDGM), and said “miscommunication” must have led to the wrong reporting of facts.

M Sridhar, director general of the GSI, said nobody in the agency gave any such data. He said 52,806 tonnes of gold ore was found in Sonbhadra district during the exploration work in 1998-2000. From this reserve, only 160 kg of gold can be extracted.

“There must have been some miscommunication of facts because of which the gold ore deposits have been overestimated. We have written a letter to Uttar Pradesh (UPDGM), stating the facts. The GSI has not estimated such kind of vast resource of gold deposits in Sonbhadra,” Sridhar said.

The UPDGM had said on Friday that gold deposits were found in Son Pahadi and Hardi areas of the district. Sridhar said while gold ore was found in the area during the GSI’s exploration work in 1998-2000, it had told the state government about the discovery in November last year.

Under the new regulation, which came into effect from 2015, the GSI has to inform the state government when ore deposits are discovered. Earlier, no such action was mandatory. In its report, the GSI estimated that only 3.03 gm of gold can be extracted from a tonne of ore. It also clarified that even the extraction amount was tentative and could not be established for certain.

Moreover, Sridhar said the deposits were spread across only 0.5 sq km in forest land, which made the mining of ore economically unviable. “When there are several mines nearby, we can club it into a block and then it makes sense to mine the ore. But in this case, the deposits are too small to make it viable for any company to mine it,” he said. The GSI usually prioritises its exploration work based on the needs of the Centre. While strategic minerals like tin, cobalt, lithium, beryllium, germanium, gallium, indium, tantalum, niobium, selenium, and bismuth are atop the list in GSI exploration, gold is another commodity on its priority list.

According to the World Gold Council, India has reserves of 630 tonnes of gold.
