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, Apr 30: Karnataka has decided to allow all industries located outside COVID-19 containment zones to operate from May 4, Chief Minister BS Yediyurappa said Thursday, even as he cautioned that the coronavirus crisis may last another couple of months.

“We feel that the COVID-19 menace is reducing and coming under control in the state. In Bengaluru, not many cases have been reported in the last 3-4 days. If this continues, it’ll help us open up industries in and around Bengaluru also. We’ll wait for another 2-3 days,” Yediyurappa told reporters after chairing a meeting of the Cabinet.

Yediyurappa and Industries Minister Jagadish Shettar are scheduled to meet industry captains on Thursday evening to discuss resuming operations from May 4.

"It won't be a surprise if the corona continues for another 2-3 months. However, based on Prime Minister Narendra Modi's directions, stringent lockdown measures (at red zones) and reviving economic activity will go hand in hand," Yediyurappa said.

The Cabinet decided to allow one-time inter-state or inter-district movement of people and labourers stranded due to the Covid-19 lockdown. The move will also benefit students and others who want to return to their native states or districts.

The government will also allow people from Karnataka residing in other states to return only if they are tested negative for Covid-19, Law Minister JC Madhuswamy said. An official order for this will be issued by evening today.

"Expenses should be covered by those wishing to travel. The government is willing to arrange buses for their benefit," Madhuswamy said. The government will provide a license to anyone who wishes to go, he said.

Having relaxed norms for industries outside red zones to resume operations, Madhuswamy said that inter-district passes will be issued to the top management of these units to travel from their homes to workplaces.

Liquor outlets, saloons and restaurants will remain closed till May 3, after which the government will take a call based on directions issued by the Centre.

“Opening of malls and hotels is not an option before us right now. But all hotels can give parcels,” Yediyurappa said. “I’m confident that the PM will allow the resumption of all activities.

He has already said that corona (containment) and economic activities will have to go hand in hand. So, I’m expecting the Centre to make some favourable decisions,” he added.
