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, Mar 30: The nationwide lockdown has left the state on the brink of a fresh agrarian crisis.

The lack of transport facilities spells doom for ready-to-harvest grapes worth Rs 500-600 crore in Bengaluru Rural, Chikkaballapur and Kolar districts. Unable to find buyers, several farmers have begun dumping their produce into compost pits.

On Sunday, Munishamappa, a farmer in Chikkaballapur, emptied four truckloads of grapes into the pit as buyers didn’t turn up due to the lockdown. “If the grapes wither and fall to the ground, it will affect the soil’s fertility and I will be forced to dispose of them,” he said.

Venkata Krishnappa, Munishamappa’s son, said their 1.5-acre vineyard yielded 25 tonnes of grapes. “Just before the lockdown, 10 tonnes were harvested and delivered to the market. Due to lack of transport, buyers haven’t turned up for the remaining 15 tonnes which we are dumping into the pit.”

Anjaneya Reddy, a farmer leader, said that in Chikkaballapur alone, they have cultivated grapes on 2,000 acres. “Even if you consider 15 tonnes per acre as yield, there are about 30,000 tonnes ready to be harvested in the district. At a market rate of Rs 50 to Rs 60 per kilogram, the net worth will be Rs 200 crore to Rs 300 crore. And if you consider the crop in Kolar and Bengaluru Rural, grapes worth Rs 500 to Rs 600 crore are at stake,” he explained.

The ‘Dilkush’ grapes is the most preferred variety of domestic consumption, according to the farmers.

This apart, farmers would have invested about Rs 3 lakh to 4 lakh per acre on fertilisers, pesticide and labour. “With markets being shut and no of the transport facilities available, farmers are forced to dump their produce into pits. It is high time the government intervened and provided us with market options so that farmers can sell at an affordable price of Rs 30 to 40,” Reddy said.

Somu, a farmer in Ganjam village of Srirangapattana, dumped two tonnes of chikku (sapota) citing market shutdown in Mandya. Reddy appealed to the government to emulate the Maharashtra model where the government is helping farmers market fruits through Hopcoms or dairy units as nutrient supplements to people.
