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, Mar 10: With concerns growing by the day, the Karnataka government is readying three more labs to test throat swab samples.

Currently, only two labs in Bengaluru — National Institute of Virology and Virus Research and Diagnostics Laboratory (VRDL) lab attached to Bangalore Medical College and Research Institute — are categorised biosafety level 2+, a requirement for coronavirus tests.

Now, the government is working on upgrading three more labs, one each in the government medical colleges at Hassan, Mysuru and Shivamogga. “The labs will be ready within one week,” the authorities said.

Currently, the labs are testing only throat swab samples of suspected patients and taking 24 hours to give the results. “A patient’s blood sample will be collected only if he or she tests positive for covid-19 infection in the first throat swab sample.

While earlier the state would send all samples of suspected coronavirus cases to NIV, Pune, the two labs were upgraded to biosafety level 2+ in mid-February.

Bengaluru, Jan 25: Several women have completed a 24-hour protest here against the Citizenship Amendment Act (CAA) and are going strong to stretch it to 48 hours.

"More than a thousand women gathered on the Masjid Road at Frazer Town to denounce the CAA and National Register of Citizens (NRC)," participant and Mount Carmel College student Noor Zahira told IANS.

The women protesters extended their support to the students in Jamia Millia Islamia, the Aligarh Muslim University, the Jawaharlal Nehru University and others who were recently roughed up allegedly by police and masked goons.

Zahira, 20, said the women's protest was planned only for 24 hours but is continuing to touch 48 hours.

Starting 3pm on Thursday, the women, several of them in burqas, niqabs and hijabs, are sitting on the road just outside the Haji Sait mosque in Frazer Town in a flash protest. Though they have informed the police, they did not wait for the permission. Around 11 pm, police arrived and shut off the protesters' loud speakers.

Zahira said already four such women's anti-CAA protests were taken out in Bengaluru. Women from all ages groups have joined the protest and are sloganeering.

As the women are protesting on the road, men are guarding them standing on the opposite road, ensuring all supplies such as food and others to them, she added.

"Muslim women were not alone in denouncing the CAA... we were joined by the transgenders, Hindu women, Christian women, Dalits and others, " she said.

Some of the protesters also indulged in creative work such as composing songs against the CAA and making placards.

Though four anti-CAA women's protests happened at the Town Hall and other landmarks in Bengaluru, they were only a few hours long.

The protesting women are also showing support to women protesters at Shaheen Bagh in Delhi who were accused of demonstrating for Rs 500. However, the protest did not align anti-CAA demonstration with any political party, keeping it apolitical.
