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 7: There seems no impact of Covid-19 on kharif crop sowing in Karnataka with the current year actually being ahead of previous years, according to an official here on Monday.

"In agriculture, as far as sowing is concerned, there is no impact of COVID-19," Agriculture Commissioner Brijesh Kumar Dikshit told IANS. One of the reasons, according to Dikshit, is that people in rural areas are aware, but not scared of the pandemic.

"In rural India, coronavirus is there. People are aware, not scared. They are taking precautions, but don't have any phobia," he said.

Another reason was that by June the number of infections in Karnataka was not as high as other states, when a lot of sowing was done, he said.

By the end of June, Karnataka saw 15,242 Covid-19 cases. Of that, 7,074 were active.

The sowing is ahead of previous year as it's mostly dependent on weather. "It's ahead of previous years. Agriculture is directed by weather and rains had been slightly earlier this year," he said.

According to Karnataka State Natural Disaster Monitoring Centre, at 185 mm the state received 14 mm less rain in June against the normal 199 mm. "It's like a normal year, or slightly a good year," he said.

Some crops will be sown in the last fortnight of July and few more will extend up to August 15. "The last two weeks will be critical and on July 31 we should be able to tell whether we are short or ahead," he said.

According to preliminary indications, the Commissioner said the area under agriculture is increasing this year, which could also be because that labourers might have come back.
