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, Jan 18: Congress leader Siddaramaiah targeted Union Home Minister Amit Shah soon after he arrived in Bengaluru on Saturday, demanding his answers on various questions pertaining to the state.

In a slew of tweets under the #AnswerMadiShah banner, Siddaramaiah raised issues ranging from the August 2019 floods to the recent police shootout in Mangaluru that killed two people during an anti-CAA protest.

On December 19, Jaleel (45) and Nausheen (24) were killed after the police opened fire during a protest against the CAA.

“Two innocent victims were killed in Mangaluru in what public opinion says that it is a fake encounter. You are the Home Minister of the country. Don't you think adequate investigation has to take place when people cry foul about the incident?” Siddaramaiah asked.

He further asked: “Mr Amit Shah, before investing time to brainwash people to accept your divisive policies, why don't you visit flood-affected areas again and assess if the Central government funds  are sufficient or not?”

The Congress leader pointed out that Chief Minister BS Yediyurappa had claimed that Karnataka suffered losses of over Rs 35,000 crore due to the floods. “But your aid is just Rs 1,870 crore. When are you planning to give the remaining? Will there be any funds left after the implementation of CAA, NPR & NRC?” he added.

The former chief minister brought up the Mahadayi river water sharing dispute. It may be recalled that Shah, in the run-up to the Karnataka Assembly elections in 2018, had promised a resolution to the dispute within six months if BJP was voted to power in the state.

“Mr. Amit Shah, your colleagues give contradictory statements on the initiation of Mahadayi project. Why is there a change in stance after elections? What is your stand on the issue,” Siddaramaiah asked.
