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.

The apex court, on November 9 last year, had directed the Central government to hand over the site at Ayodhya for the construction of a Ram temple.

The formation of Shri Ram Janmabhoomi Teertha Kshetra Trust was announced on February 5 for the construction of Ram temple at Ayodhya. The Trust has been mandated by the Central government to oversee the construction of Ram temple in Ayodhya.

"No pro-people schemes must be stopped including Indira canteen, Yediyurappa thinks Indira canteen will bring good name to me that's why this government is trying to stop it," he added.

Bengaluru, Jun 29: Former Karnataka Chief Minister Siddaramaiah along with Congress leaders on Monday rode a bicycle from his residence to Minsk Square to protest against the hike in fuel prices.

KPCC President DK Shivakumar was also seen riding a bicycle along with other members of the Congress party to Minsk Square where the party staged the protest.

During the protest, Siddaramaiah and Shivakumar along with party leaders carried a bike on their shoulders.

"We are carrying out our duty today. At the time of the UPA government's rule, when there was any hike in fuel prices, several BJP leaders had made bold statements. It is ironic that today, at the time of this COVID-19 pandemic, even despite the price of barrels falling, they have increased fuel prices," said Shivakumar.

"In Delhi, diesel prices have exceeded petrol prices. We must protest against this. The DCP can file whatever case he wants to. Despite several cases against us, we have never been shaken up. They are inconveniencing people and causing the people to burn in hell. These people must be protected," he added.

With the hike in fuel prices, the petrol prices stand at Rs 83.04/litre (increase by Rs 0.05), and the diesel prices stand at Rs 76.58/litre (increase by Rs 0.13) in Bengaluru, according to a price notification of state oil marketing companies.

The Congress has termed the increase in the prices of petrol and diesel as "unjust" and "thoughtless", and urged the Central government to roll back the increase with immediate effect and pass on the benefit of low oil prices directly to the people.
