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: Karnataka chief minister BS Yediyurappa on Tuesday shuffled the portfolios of six newly inducted ministers after they expressed unhappiness about the departments allocated to them barely 24 hours ago.

Three ministers — BC Patil, Anand Singh and K Gopalaiah — received new responsibilities and as many — Shivaram Hebbar, Srimanth Patil and Byrathi Basavaraj — have been saddled with more.

Sources said the six ministers met the CM late Monday night and said they were not happy with the portfolios handed to them. They reportedly threatened not to assume office until their demands were met, forcing the CM to effect the changes early Tuesday.

BC Patil is now vested with agriculture (he had been given forest), Anand Singh forest, environment and ecology (earlier food and civil supplies) and Gopalaiah food and civil supplies (instead of small-scale industries). BC Patil said, “I’m happy I can now be with farmers.” Shivaram Hebbar has been given the additional responsibility of sugar along with labour allocated to him on Monday.

Allocation of the forest portfolio to Anand Singh has raised eyebrows as the Vijayanagara MLA had been arrested in 2013 and 2015 in cases of illegal mining and illegal transportation of mining ore. Singh owned SB Mineral in Ballari and the Lokayukta had charged him with transporting 17,086 tonnes of iron ore without permission or valid licence. He was acquitted in a Belikeri iron ore export case due to lack of evidence.

Byrathi Basvaraj, who has been given the urban development ministry, will also handle Karnataka Urban Water Supply and Drainage Board and Karnataka Urban Infrastructure Development and Finance Corporation.

Srimanth Patil has received minority welfare department apart from textile.

The exercise of portfolio shuffling is likely to continue with minister K Sudhakar reportedly unhappy with medical education.

In another embarrassment to the CM, Mahesh Kumathalli on Tuesday refused to take over as chairman of the Mysore Sales International Ltd, saying he wants to be a minister. BJP MLA Basanagouda Patil Yatnal urged Yediyurappa to induct Kumathalli into the cabinet in line with the promise made to him when he joined the BJP before bypolls. “The CM must keep his word,” he said.

New Delhi, Mar 30: Congress MP Rajmohan Unnithan on Monday approached the Supreme Court seeking directions to open the Karnataka-Kerala border to allow movement of ambulances and other emergency vehicles for the transport of essential items to Kerala.

Unnithan, who is an MP From Kerala's Kasaragod constituency, filed a plea seeking direction to Karnataka to open the borders with Kerala and in particular Kasargod-Mangalore border at Talappadi.

The petition sought directions to Karnataka to allow the movement of ambulances, emergency vehicles, trucks and other vehicles carrying essential and non-essential items to Kerala. It also sought to stay the blockade imposed by Karnataka with its border states.

The plea also sought directions to Karnataka to register an FIR and constitute a special investigation team (SIT) under the supervision of this court to enquire against the concerned authorities including the police officials whose action led to the death of two citizens.

It said that the imposition of such a blockade at a time when the supply of commodities is itself hit hard and when a medical emergency has plagued the entire country is a clear violation of Articles 21 and 19(d) of the Constitution.

"This blockade has also resulted in cutting off the essential lifeline of National Highways and State Highways and major District Roads leading to the State of Kerala which has resulted in the shortage of supply of essential and non-essential items to the State of Kerala leading to shortage supply of food and medical supplies," the plea said.

"This ill-planned and dangerous blockade has claimed the life of a 70-year-old woman who was denied entry into Karnataka even for the purpose of urgent medical treatment which was only available in the medical hub of Mangalore. This is a clear case of violation of the right to life with dignity by the state as citizens are made to die on the roads because of the action of the state which is in total disregard to Article 21," it added.

This comes as the country is under a 21-day lockdown to prevent the spread of coronavirus, which according to the Ministry of Health and Family Affairs has claimed the lives of 29 people and infected a total of 1071 people as on Monday morning.
