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?

Udupi, May 16: Close on the heels of six Covid-19 cases being detected in a little over 24 hours, Udupi recorded its first death of a Covid-19 patient. The victim is a 54-year-old man from Mumbai, who died due to a heart attack on Thursday. His reports came back on Saturday, and confirmed that he had Covid-19. The Udupi district administration has arranged to carry out his last rites as per government designated guidelines for Covid-19 victims.

A medical bulletin issued by the superintendent of Kasturba Hospital, Manipal, stated that the patient was admitted due to a heart-related issue on May 13.

Some members on the team that treated the patient have been quarantined. The hospital’s emergency department will operate as usual, and the outpatient department will operate as usual from 8.30am to 1pm, following government guidelines, the bulletin said. Deputy commissioner G Jagadeesha said that since the patient was from Mumbai, the authorities collected his swab sample for testing, as a precautionary measure.

The man suffered from chest pain, and was initially taken to the taluk hospital at Kundapur from where he was shifted to Kasturba Hospital, due to the seriousness of his condition. The doctors operated on him on May 13, and he suffered a severe heart attack on May 14 and died, the DC said. “Three hospital staff without PPE kits, who attended to the patient, have been quarantined,” the DC said, adding that the operating doctors and nurses had worn PPE kits.

In addition, 5 others who travelled with the person from Mumbai and 57 people with him at the Kundapur isolation centre, have been designated as primary contacts, and 38 others as secondary contacts, and quarantined. The staff at Kundapur taluk hospital too had taken precautions in handling the patient, the DC said. Udupi presently has six active cases, including a 1-year-old child and 5 others, all of whom returned from Dubai on May 12.
