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, Jan 26: The Azizuddin Road of Mangaluru’s Bunder area, which had witnessed the brutal killing of two innocent passersby over a month ago, today witnessed the unfurling of Indian national flag by the kin of the police firing victim. 

49-year-old Abdul Jaleel Kandak, a father of two, and 23-year-old Nausheen Kudroli, were killed in an arbitrary and unwarranted police firing during a disturbance occurred due to police baton charge in the city on December 2019. 

A mixed feeling of patriotism and pain prevailed when a group of people gathered on the police firing spot to celebrate the 71st Republic Day of India. Family members of the victims were part of it.

It was Shifani, the daughter of Abdul Jaleel, who unfurled the flag and read out the preamble of the Indian constitution. 

“This is the spot where the constitution of the country was murdered,” said social activist Vidya Dinker, recalling the police firing. “The constitution is being murdered everyday in many states of India. We must regain the constitution and implement it everyday,” she added. 

Journalist Shahnaz M, DYFI leader Imtiyaz BK, SIO leader Talha, NWF leader Shahida Aslam and social activist Shabbir Ahmed were present among others.

Bengaluru, Jul 2: Senior Congress leader Mallikarjun Kharge said that the "RSS needs to be defeated to save the country" and Prime Minister Narendra Modi and Union Home Minister Amit Shah are "destroying the nation".

Kharge was speaking at a KPCC program where DK Shivakumar took charge as state Congress president.

He said that the Prime Minister and the Home Minister are not ready to take accountability for any issues including China, and are instead blaming Rajiv Gandhi Foundation of getting funds from China.

"Rajiv Gandhi foundation utilized funds for the development of the nation and for the betterment of the downtrodden people," Kharge said.

"Prime Minister Modi and Shah both are destroying the economy of the nation, and their policies and plans are the reason for increasing COVID-19 situation in India," he said.

"Prime Minister and Amit Shah never listen to Opposition parties, instead they plan something and their policies are the reason for MSME losses and job losses in the country," he added.
