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?

Between April-June 2020 the Bengaluru airport saw only 4.54 lakh total passengers (domestic and international) as against 84.11 lakh total passenger during the same period last year. The number of flights to and from Bengaluru also saw a huge dip in June with only 731 international (2,582 in June 2019) and 4290 domestic (16,216 in June 2019) flights.

Though the Mysuru domestic airport handled a higher number of flights compared to last June, the number of passengers either arriving or departing saw a decline. Last year June 4,775 passengers travelled in 96 flights, whereas in June 2020 the airport handled 3,158 passengers and 330 flights.

Hubballi airport saw the least number of passengers or flights among the seven airports in Karnataka in June. It saw only 55 passengers either arriving or departing from the city's airport in 14 flights in the month of June. In the same month last year, Hubballi airport, which was third busiest before the pandemic, had facilitated 45,973 passengers and handled 604 flights.

Bengaluru, Feb 19: Congress MLA UT Khader on Wednesday slammed the Central government over the enactment of the Citizenship (Amendment) Act and said it violates the Constitution.

"The new citizenship amendment bill is unconstitutional. The citizenship cannot be given on cast and creed basis. Because of these things we are fighting against it," he said while speaking to media in Bengaluru.

Opposition along with several non-BJP state governments, including Madhya Pradesh, West Bengal, Kerala, Punjab and Rajasthan have refused to implement the Citizenship Amendment Act (CAA) and the proposed NRC in their respective states.

The CAA grants citizenship to Hindu, Sikh, Jain, Parsi, Buddhist and Christian refugees from Pakistan, Afghanistan and Bangladesh, who came to India on or before December 31, 2014.
