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.

Mangaluru, Apr 12: Swift and strict action by the District Administration has resulted in the district achieving ‘Clean’ week with no new cases of COVID-19 reported for the seventh day in a row.

Meanwhile, in a happy coincidence, the district’s only infant allegedly affected – a ten month old child – was totally cured and discharged from the hospital along with infant’s mother and grandmother who were considered to the primary contacts. They are never tested positive for the virus, it is reported. Health experts attributed this to their natural immunity.

The child is said to have contracted the infection during a family visit to Kasargod, which has turned in to a Covid-19 hot spot. The family which hails from Sajipanadu in Bantwal-taluk had been kept in isolation ever since the child had tested positive on March 25. The quarantine was extended to the entire village as a preventive measure and the District Administration undertook the responsibility to providing essential supplies.
