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 19: In the wake of assurance by Chief Minister B S Yediyurappa to look into their demands, hotels and restaurants in Karnataka today decided to continue takeaway services for three more days.

Hotels were also exempted from the total lockdown on Sundays in Karnataka - under the state guidelines issued for Lockdown 4.0.

The Karnataka Pradesh Hotel and Restaurants' Association (KPHRA) had earlier threatened to stop takeaway services over refusal to allow dine-in facility in the fourth phase of the lockdown. 

B Chandrashekar Hebbar, president of KPHRA said that the CM urged hoteliers to wait for three days, assuring that a decision will be taken. 

"We appraised the government over the mounting losses by keeping just take-away services open. Noting that social distancing and other guidelines will be followed, we urged him to allow dine-in facility," he said.

The Association will wait three more days before discontinuing parcel services, Hebbar said. 

The government also provided relaxation to hotels from the total lockdown announced in Karnataka on Sundays, he said. 

A package for hotel employees such as cooks and waiters, along the lines of those announced for farmers, cab drivers and weavers, was also sought in a petition submitted to the chief minister.

In fact the state government had expressed its willingness to open hotels under the Lockdown 4.0, subject to restrictions. However, the central guidelines do not allow dine-in services.

Bengaluru, May 25: Karnataka Chief Minister B S Yediyurappa on Monday greeted the Muslim brethren on the occasion of Eid-ul-Fitr, which is being celebrated in a subdued manner due to coronavirus related restrictions.

"Warm greetings of Eid-ul-Fitr. May this festival of peace and harmony bring happiness in life," Yediyurappa said in his message.

He congratulated the Muslim fraternity for cooperating with the authorities by offering prayers at home during the holy month of Ramadan and supporting the government to contain COVID-19.

"I hope the same trend will continue during the festivities of Eid-ul-Fitr too. I thank you all for your support in the fight against COVID-19," he said.

The Eid festivities were a low-key affair as Muslim brethren celebrated the festival indoors in view of lockdown to contain coronavirus on Monday.

People offered the special prayers inside their houses instead of performing it in mosques and Eidgah, the open field to perform prayers, and refrained from going out to greet each other.

As the Karnataka government has ordered Sunday Curfew throughout the lockdown-4 till May 31, the otherwise bustling markets in the urban areas of Karnataka remained shut.

People could not venture out to make necessary purchases on Sunday.

The Jama Masjid of Bengaluru at the City Market had asked the Muslims to offer prayers inside their houses and not go to the burial grounds to express their sentiments for the departed souls.

"Mass prayers are not allowed anywhere in Karnataka. Just five important persons managing the mosques offered the prayers. Similarly, people go to the graveyard to pray for the dead ones but this time we asked people to express their sentiments from inside their homes instead of going to the burial grounds," Maulana Maqsood Imran, the Khateeb-O-Imam, Jama Masjid, Bengaluru, told news agency.

He said, "coronavirus is spreading very rapidly in our country. If we don't follow the guidelines, it will not only cause trouble to us but also to the doctors and the government. It will be the biggest celebration if we abide by the norms."
