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 8: The all-India shutdown by trade unions and other organisations began with little impact in the tech city as normal life continued on a working day, an official said.

"No effect of shutdown in the city though banking operations are affected as bank staff are supporting the trade unions," a state official said here.

However, thousands of workers participated in other parts of Karnataka in the nation-wide shutdown call given by trade unions, protesting central government's anti-labour laws and privatisation policies.

Protesters were seen carrying the red trade union flags at several places such as Hassan, Chamarajanagar, Tumakuru, Mysuru, Bengaluru and others.

Massive protests were seen in Peenya, and Neelmangla areas of Bengaluru.

In Madikeri, stones were pelted at a bus and some protesters were detained in Kolar.

The trade unions are against the privatisation of railways and corporatisation of 49 defence production units.

Merging 44 labour laws into four code is also one of the demands of the protesting trade unions.

The protesters are demanding raising the minimum wage in the range of ₹21,000 - 24,000 per month.

The All India Trade Union Congress (AITUC), Centre of Indian Trade Unions (CITU), Indian National Trade Union Congress and Labour Progressive Federation (LPF) have given an all-India shutdown (Bharat Bandh) call on Wednesday.

Karnataka Chief Minister B.S. Yediyurappa instructed the intelligence chief and additional director general of police Kamal Pant to maintain law and order in view of the Bharat bandh when he apprised him of the situation.

Police tightened security across the city by deploying 11 deputy commissioners of police (DCPs), 23 assistant commissioners of police (ACP), 111 inspectors, 316 sub-inspectors, 476 assistant sub-inspectors, 4,547 constables along with 82 platoons of Karnataka State Reserve Police (KSRP).
