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.

Mysuru, May 6: A seven-months pregnant woman fled Covid-19 hotspot Mumbai along with her family, and made it to her village 1000 km away in KR Pet taluka in Mandya district of Karnataka, flashing her mother's ID card at each checkpost. After reaching her destination, she got herself tested for Covid-19.

She tested positive for the virus on Monday in Mandya.

The 20-year-old woman (assigned the number P637) had been living with her husband and in-laws at Santa Cruz East, Agripada in Mumbai for the past three years. To get out of the containment zone, they started out from Mumbai at 7.30 pm on April 23 -- she, her husband, brother-in-law, co-sister and their children, and a 19-year-old girl. She made it past checkposts at Belagavi, Hubballi, Davanagere, Kadur, Arasikere, Channarayapatna and Shravanabelagola and reached her village Jaaginakere at 3 pm on April 24.

She stayed at her home in the village from 24 April to April 29. With the Mandya district administration testing people on a campaign mode in the entire district, she and her family got themselves tested on May 1.

Her test returned positive on May 4, according to deputy commissioner M V Venkatesh.

Along with her, the 19-year-old girl (P638) who travelled with the family also tested positive. The girl is in the sixth semester of her BE Electronics course at an engineering college in Mumbai.

This is not the first case of a corona fugitive from Mumbai. Earlier, a 50-year-old man who ran a hotel in Mumbai travelled in a vehicle carrying dates and reached Channarayapatna in Hassan district.

In fact there have been three such incidents, including that of seven people coming to Mandya from Mumbai transporting a dead man's body for cremation in his native village of B Kodagalli in Pandavapura taluk.

Mandya deputy commissioner Dr Venkatesh has appealed to natives of Mandya who are stuck in Mumbai to stay there till the Covid situation comes to control.

So far 28 people in Mandya diatrict have tested positive for Covid 19. Seven people have been discharged. Currently there are 21 active cases being treated at the Mandya Institute of Medical Sciences.

Bengaluru, May 2: JDS leader and former Karnataka Chief Minister HD Kumaraswamy accused the Mandya district administration of the surge in COVID-19 cases in the district and not quarantining 7,000 labourers who arrived here from Mumbai.

"As we know that 16,000 labourers from Mandya were working in Mumbai, out of which 7,000 people have arrived in the district. However, none of them was quarantined properly which is a violation of COVID-19 lockdown," Kumaraswamy told reporters here on Friday.

He claimed the district administration has shown "gross negligence" in their duty in following the procedure of COVID-19 as "one COVID-19 patient's dead body which was brought here from Mumbai has led to more cases in the district and those who accompanied the body have also tested positive for the virus."

Kumaraswamy appealed to the state government to strictly maintain lockdown norms and do not allow any relaxations in view of the rise in COVID-19 cases, stating that "any kind of relaxation could lead to a huge disaster."
