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 15: All 21 Madhya Pradesh MLAs from Jyotiraditya Scindia's camp, who were lodged here at Prestige Golfshire Club, have been shifted to Ramada hotel in Yelahanka ahead of Monday's floor test in the state assembly.

In view of their arrival, the concerned authorities have strengthened security outside the hotel.

Following the exit of Scindia from Congress, these MLAs claimed to have resigned from the state Legislative Assembly.

On March 11, Congress sent two of its leaders -- Sajjan Singh Verma and Govind Singh -- to Bengaluru in order to pacify some of these rebel MLAs.

Most of the rebel MLAs are perceived close to Scindia and were apparently unhappy at Scindia being "ignored" in the party.
Meanwhile, Madhya Pradesh Congress MLAs, who arrived in Bhopal from Jaipur today morning ahead of the floor test in the Assembly on Monday, have been shifted to Courtyard by Marriott Hotel.

These MLAs were accompanied by senior Congress leader Harish Rawat, who exuded confidence of Kamal-Nath led government winning floor test in the Assembly.

Both Congress and BJP have issued whips to all its MLAs for the legislative assembly session in Madhya Pradesh, which is scheduled to be held from March 16 to April 13.

On Saturday, Madhya Pradesh Governor Lalji Tandon had directed that a floor test will be held in the assembly on Monday.

Bengaluru, May 5: Life is limping back to a new normalcy in most parts of Karnataka with easing of Covid-19 induced restrictions yesterday as the State headed into the third phase of lockdown started since March 24.

According to the guidelines issued by the Centre, industrial activities, construction works, essential, non-essential shops, delivery of essential goods through e- commerce, courier and postal services, banking and agriculture activities, plying of four-wheelers and two-wheelers and inter-state movement of goods vehicles is permitted in all the zones, whereas buses are allowed to ply only in green and orange zone districts.

This apart, sale of liquor was also allowed at the designated shops. Police said vehicular movement is allowed only from 7am to 7pm for ordinary citizens.

Clarifying about the movement of people, Bengaluru police commissioner Bhaskar Rao tweeted, "From Monday you don't need a pass to move in Bengaluru between 7am and 7pm. After 7 pm and up to 7am the following morning, even if you have a pass you are not allowed to move except medical and essential service. Checkpoints will remain and your ID may be asked. Please be responsible." After the restrictions were lifted, heavy vehicular movement was witnessed in parts of Bengaluru leading to traffic jam in some areas.

Chikpet, which is the main trade area in Bengaluru, saw some activities.

With restrictions on public transport continuing, this unusually crowded place had very less footfall. "Movement of public is limited due to ban on public transport, such as city buses and Metro Rail.

"The trade activities are taking place between retailers," trade activist and joint secretary of Jain International Trade Organisation Sajjanraj Mehta said .

Select liquor shops in the city and other parts of the state pulled up shutters after being closed for about six weeks due to the lockdown with tipplers thronging them in huge numbers at many places.

Some traders in the city complained that they received notices regarding the Tax Deduction at Source for the month of April "thought here were no trading activities."

Meanwhile, Chief minister B S Yediyurappa announced on Monday that free bus service for migrant labourers, which is operating smoothly, has been extended till Thursday.
