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.

During the meeting it was also decided to continue more than 3,000 home guards, who were in the fear of losing jobs, and to deploy them to various departments.

Yediyurappa directed officials to take necessary steps to make home guard services available to private organisations also. Officials informed the Chief Minister that all necessary COVID-19 related precautions have been taken at prisons and no case has been reported so far at jails. They said as per Supreme Court directions, 5,005 people were released on bail and parole, and congestion of prisoners at prisons has been reduced from 110 per cent to 95 per cent.

Feb 28: The Supreme Court on Friday granted more time to the Central Bureau of Investigation (CBI) to file a counter affidavit on a petition filed by Karnataka BJP leader and mining baron Gali Janardhana Reddy seeking permanent relaxation on his bail condition to allow him to visit Karnataka's Bellari and Kadapa in Andhra Pradesh.

A bench of Justices Arun Mishra and Indira Banerjee listed the matter for further hearing on March 16 after the CBI sought more time to do file the counter affidavit.

Earlier, the apex court had issued a notice to the CBI and sought its response on the plea.

Last year, the Court had allowed Reddy to visit the Ballari district for a period of two weeks to meet his father-in-law, who the petitioner claimed had suffered a stroke and also allowed him to move a bail modification application seeking permanent relaxation of his bail condition.

In January 2015, the Supreme Court had granted bail to Reddy in an illegal mining case involving Obulapuram Mining Company (OMC) on the condition that he will not visit any of the mining zones in Karnataka or Andhra Pradesh.

By the time he was granted bail, Reddy had already spent over three years in prison.

Reddy and his brother-in-law BV Srinivas Reddy, who was the Managing Director of OMC, were arrested by the CBI on September 5, 2011.
