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, Jul 16: Former Prime Minister and JDS supremo H D Devegowda on Thursday gave a clarion call to party workers to take steps to strengthen the party from the grossroots level and to 'expose the failures' and 'anti-people' policies of BJP government both at the Centre and State.

In an open letter to the workers here, he alleged that the urgent need is to create awareness among the people about failure of the governments which have brought in policies which are deterrent to the poor and downtrodden.

BJP government headed by Chief Minister B S Yediyurappa in Karnataka has come up with an amendment to the Land Reforms Act,1961, which is 'against' interests of the small and medium farmers as even a non-agriculturist can purchase agriculture land, thus giving an opportunity to the rich people to 'exploit' illiterate farmers and purchase their land and use it for some other purpose after some time.

Bengaluru, June 5: Under the leadership of trouble-shooter D K Shivakumar, the Karnataka Congress is planning a political ‘ghar wapsi’ to bring back leaders who quit the party and also rope in those from other parties.

Shivakumar, the Karnataka Pradesh Congress Committee (KPCC) president, has constituted a 12-member committee headed by former minister Allum Veerabhadrappa to liaise to anchor this effort to bring back people into the party fold. 

The committee comprises of former legislators B A Hasanabba, Ajaykumar Sarnaik, Abhaychandra Jain, Satish Sail, Prafulla Madhukar, former MPs R Dhruvanarayan and BN Chandrappa, MLA V Muniyappa, former mayor Sampath Raj, Mahila Congress leader Kripa Alva and former KPCC general secretary V Y Ghorpade. 

This move comes more than a year after over a dozen Congress MLAs defected and joined the BJP, leading to the collapse of the Congress-JD(S) coalition government. Also, several influential leaders quit the party ahead of the Lok Sabha elections last year.

The constitution of this committee also coincides with disgruntlement brewing within the ruling BJP. 

“Many people who left the party and others have applied (to join Congress). Many have met me also. I felt it wouldn't be right for me to make a decision. So, this committee has been constituted,” Shivakumar said. “They will process all applications and send it to the KPCC.” 

According to Shivakumar, any person wanting to join the Congress should accept the party’s leadership and its ideology. “Importantly, they should be first accepted by the cadre. If there's no acceptance from the cadre, then what's the point?” he said.

Udupi, Apr 24: While several state governments and NGOs are actively working to provide essentials to the needy amid the COVID-19 lockdown, a fisherwoman in Karnataka's Udupi has proved that even a small gesture of help for others can make a huge difference in the society.
A fisherwoman, Sharadakka, distributed rice to 140 needy families in her neighbourhood during the ongoing lockdown. The contribution was made by spending all her life savings amounting to Rs 30,000. The amount was saved by her over a period of time in an effort to build a house for herself.
On Thursday Udupi Deputy Commissioner G. Jagadeesh visited her and ensured help to build her house.
"Spending her meagre earnings, Sharadakka generously filled many empty stomachs amid the nation-wide lockdown, which is a matter of pride," said the Deputy Commissioner.
