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.

Bhopal, Mar 10: Senior Congress leader Digvijay Singh on Tuesday parried questions on the exact number of MLAs supporting the party in Madhya Pradesh amid a political crisis triggered by the resignation of Jyotiraditya Scindia and 14 MLAs loyal to him.

Repeating his allegation that the BJP was trying to destabilise the Congress-led government, Singh told reporters that the BJP had arranged three chartered planes for Bengaluru on Monday to fly out some MLAs loyal to Scindia.

"We want to know why Bengaluru is used every time to destabilise governments?" he questioned.

When asked about the number of MLAs supporting the Congress in the current political scenario, Singh only said, "Just wait".

He said an atmosphere of uneasiness has been prevailing in the BJP since the Kamal Nath government started cracking a whip on various mafias.

"We (the state government) are exposing Vyapam scam, e-tendering scam, Madhyam scam. In the honey-trap case, BJP men were found to be involved. This will be exposed," he said.

The political crisis in Madhya Pradesh precipitated with the resignation of Jyotiraditya Scindia over his apparent marginalisation in the state politics. Following Scindia's suit, 14 legislators loyal to him have sent their resignation letters via e-mail to Madhya Pradesh Raj Bhavan.

Scindia was subsequently expelled from the Congress by party president Sonia Gandhi.

Speculation that the Guna royal might join the BJP gained ground after he met Prime Minister Narendra Modi in Delhi this morning.

Bengaluru, May 18: Over two months after his appointment as the Karnataka Congress President, DK Shivakumar is likely to take-over the reigns of the party officially on May 31.

"There are two dates, May 31 and June 7. He is most likely to officially take over as KPCC President on the 31st," sources close to Mr Shivakumar told PTI.

After remaining in a virtual vacuum for nearly three months, the party high command on March 11 appointed Mr Shivakumar, known to be the Congress' chief troubleshooter in crisis situations, replacing Dinesh Gundu Rao as KPCC chief.

Mr Rao had quit the post in December 2019 after the party's dismal show in the bypolls when it won only two of the 15 seats and yielded 12.

Congress sources said once the appointment letter came from the high command, he has been KPCC president and officially taking charge was just a formality.

"He will be officially handed over the party insignias and responsibilities relating to bank accounts and cheques, among other things, that has been traditionally followed," they said, adding the official take over was delayed by the coronavirus.

After his appointment as KPCC president, Mr Shivakumar has been meeting a host of senior party leaders and leading the party in the fight against coronavirus.

These include setting up of Congress' COVID-19 task force, alerting the government in its management of the crisis, holding weekly video conferencing with leaders of party's local units to gather information, among other things.

Sources close to Mr Shivakumar said the official take over would be a simple event, looking at the current situation due to the pandemic.

"Very few select party leaders and office bearers, say about 50 odd people, are likely to be in attendance at the simple event at KPCC office," they said, adding that arrangements may be made to telecast the event live for the benefit for party workers and local leaders.

A six-time MLA, Mr Shivakumar had a long wait for his appointment to the coveted post, due to opposition within. There were reports that Congress Legislature Party leader Siddarmaiah had lobbied in favour of one of his confidants for the top job.

In a first, appointment of three KPCC Working Presidents- Satish Jharkiholi, Saleem Ahammed and Eashwar Khandre, was seen as an attempt by those apposing Mr Shivakumar, to weaken his hold on the party.
