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.

Gokak, Jul 25: A JMFC magistrate here issued summons to the Chief minister B S Yediyurappa in relation to a complaint for the alleged violation of election code of conduct, during by-elections to the Gokak Assembly seat held last year.

According to official sources, a complaint had been registered against Chief minister B S Yediyurappa during the election campaign, under the People Representative Act, for allegedly wooing voters during electioneering.

The Gokak Police, who had investigated the case, however had submitted a 'B' report to the court letting off the Chief minister from the charges.

However the Magistrate, rejecting the Police report, had maintained that there exists prima facie case against the accused and issued summons to appear before the court on September one, the sources added.

Bengaluru, June 23: Karnataka Congress chief D K Shivakumar has urged his party colleagues to be active on social media to counter the propaganda of Bharatiya Janata Party.

Speaking to media persons, the KPCC president said that no more than 20 out of the 68 Congress MLAs are active on social media.

“All those MLAs who are doing well need to be projected. We want leaders, not mere followers. They all should be the face of Congress in Karnataka. Party should not depend on just my face or Siddaramaiah’s,” he said.

Shivakumar’s diktat has resulted in the party’s social media unit scrambling to get leaders to create their accounts.

“We’re pressuring all the party MLAs and leaders. We’re asking their personal assistants or gunmen to operate their accounts if they are not savvy with social media,” KPCC social media chief A N Nataraj Gowda said.

He pointed out that the 20 MLAs who are active on social media include U T Khader, Dinesh Gundu Rao, Priyank Kharge, Krishna Byre Gowda among others.

“We’re also trying to get the accounts verified of those who are beginning to get active. For example, it was only recently that we got the accounts of S R Patil and Vijay Singh verified,” Gowda said.

Tapping the full potential of social media is crucial for the Congress because the BJP has found much success in reaching out to voters through various online platforms.

In fact, ahead of the 2018 Assembly elections, the Congress found that there were 10 ministers and some 40 MLAs who had turned a blind eye towards social media.

Shivakumar said he was also working on putting in place a system in the party under which all developments related to the state and country will be communicated to all party leaders at 10 am every day.
