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?

Mangaluru/Mysuru, May 19: Though the Karnataka government permitted the private buses, operators in Dakshina Kannada district have decided not to operate buses until May end. In Mysuru district too the private buses remained off the roads.

Dakshina Kannada Bus Owners’ Association President Dilraj Alva said “Technically, private bus operators are not able to operate services as all of us have surrendered our permits. If we start services we will have to pay the tax for entire month. Hence, we have decided to resume bus services from June 1.”

The private buses had suspended their services since March 24.

In addition, bus owners also have two more demands which the state government needs to consider on priority, he said.

“We have requested the government to exempt private buses from paying tax for the next six months. We were not plying buses during lockdown and it will be tough for us in the next three months to operate as per new conditions.”

“The government has allowed only 30 persons in each bus to maintain social distancing. In addition, we have been urging the state government for bus fare revision since 2013. The government has revised the bus fares of KSRTC twice after that,” Alva said adding that bus owners will be meeting Mangaluru RTO on Tuesday.
