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, Jan 6: Chief minister BS Yediyurappa has plenty on his plate ahead of the 2020-21 state budget to be presented on March 5 what with the economic slowdown and a sizeable shortfall in revenue, but the biggest worry is the uncertainty surrounding Goods and Services Tax (GST) compensation from the Centre.

There is also uncertainty over the state’s share under devolution of funds as per the 14th Finance Commission recommendation.

Finance department officials say that while Rs 3,500 crore is expected as GST compensation for every two months, the devolution of funds would have yielded about Rs 7,000 crore for the current fiscal. But the economic slowdown appears to have hit the Centre’s finances and is likely to impact the state’s share of funds.

“The GST payment for August-September came only in December and we are unsure how much we will get for October-November and December-January,” an official said. Estimates suggest the state’s share under devolution of funds could be reduced by half.

At a meeting of finance department officials last week, Yediyurappa is said to have admitted that unlike those states where non-BJP parties are in power — they have threatened agitations and court cases — the government cannot go “against” Prime Minister Narendra Modi’s regime.

Instead, Yediyurappa has urged senior IAS finance department officials to lobby for funds with their counterparts in New Delhi. On his part, Yediyurappa is said to have already written to Modi and finance minister Nirmala Sitharaman to at least release the state’s share of GST compensation for the current calendar year of 2019. He is planning to personally meet the PM in Delhi to push the state’s case.
