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.

Bengaluru, Apr 18: Virtually defending the Gowda family for conducting a marriage reportedly defying lockdown restrictions, Chief Minister B S Yediyurappa on Tuesday said it was performed in a simple manner and well within their limits, "for which they are to be congratulated."

"All the necessary permissions were given and the marriage was performed in a simple manner. There is no need to discuss about it. They had done it well within their limits for which I congratulate them," Yediyurappa said to a query from reporters during the post-COVID-19 briefing.

Scores of people had thronged a farmhouse on Friday to get a glimpse of the wedding of former Prime Minister and JD (S) supremo, H D Deve Gowda's grandson Nikhil Kumaraswamy, ignoring appeals not to visit the venue in view of the ongoing lockdown to check the COVID-19 outbreak. Nikhil, son of former Chief Minister H D Kumaraswamy, tied the nuptial knot with Revathi, the grand-niece of former Karnataka housing minister M Krishnappa.

The marriage was solemnised at Kumaraswamy's Kethaganahalli farmhouse at Bidadi in the neighbouring Ramanagara district, a JD(S) stronghold. Kumaraswamy had taken to Twitter after the marriage, thanking his party MLAs, leaders and workers for staying away from the event and blessing his son from their houses. In a series of tweets, he had said social distancing was maintained and all precautionary measures were taken throughout the event.

BJP had hit out at the JD(S) first family for flouting the norms, alleging that at least 150 to 200 vehicles were given permission to attend the event, that too at at time when social workers wanting to serve the badly affected poor people were not being allowed to ply any form of transport JD(S) leader N H Konareddi and MLC T A Sharavanna had denied the charges, saying the union government guidelines had been followed and that social distancing was maintained.
