Mangaluru prone to earthquakes, says survey

May 6, 2015

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?

Bengaluru, Jul 19: A viral video claiming to show crowded condition of a hospital treating COVID-19 patients in the city was found to be false with police on Sunday arresting a person for allegedly circulating it on social media.

Police said such videos have the potential to create panic and asked people to refrain from spreading them.

The arrest was made within hours of the police announcing registration of a case in connection with the video that showed a crowd of people wearing masks at an "outpatient ward" of a hospital, falsely identified as Victoria Hospital, a major dedicated COVID facility here.

The video went viral on social media.

"City Crime Branch swiftly identified and arrested this person who has been circulating false videos of panic in Victoria Hospital, Bangalore. Kudos to all doctors and medical professionals who are doing their best. False news busted," Bengaluru Police Commissioner Bhaskar Rao tweeted.

Police said such videos have the potential to create panic in society and asked people to refrain from it.

"Covid False video about conditions of hospitals in Bangalore circulated on social media. Case registered in Cybercrime PS. While government, society at large fighting the pandemic, some are creating/forwarding messages/videos which has potential to create panic in society. Refrain from it," Joint Commissioner of Police, Crime, Sandeep Patil tweeted.

The video showed scores of people wearing masks gathered in a small space allegedly at an Out-Patient Department in a hospital, and a person filming it, claiming to be a doctor expressing concern that it was a threat to all medical staff, including the patients.

Official sources said the video was reportedly from a hospital in one of the northern states and not from Victoria Hospital.
