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, Jun 27: A Karnataka government employee on SSLC exam duty at a school in Pavagada, Tumakuru district, on Friday tested positive for Covid-19, prompting the education department to send all staff members of the exam centre on quarantine.

“No student has been affected. All the staff has been replaced,” said R Umashankar, principal secretary, education department.

How soon we get a coronavirus vaccine depends on not only the pace of work in research labs, but also the preparedness of factories supplying glass vials, stoppers and syringes

India ranked 77th on a sustainability index that takes into account per capita carbon emissions and ability of children in a nation to live healthy lives and secures 131st spot on a flourishing ranking that measures the best chance at survival and well-being for children, according to a UN-backed report.

The report was released on Wednesday by a commission of over 40 child and adolescent health experts from around the world. It was commissioned by the World Health Organization (WHO), UN Children's Fund (UNICEF) and The Lancet medical journal.

In the report assessing the capacity of 180 countries to ensure that their youngsters can survive and thrive, India ranks 77th on the Sustainability Index and 131 on the Flourishing Index, it said.

Flourishing is the geometric mean of Surviving and Thriving. For Surviving, the authors selected maternal survival, survival in children younger than 5 years old, suicide, access to maternal and child health services, basic hygiene and sanitation, and lack of extreme poverty.

For Thriving, the domains were educational achievement, growth and nutrition, reproductive freedom, and protection from violence.

Under the Sustainability Index, the authors noted that promoting today's national conditions for children to survive and thrive must not come at the cost of eroding future global conditions for children's ability to flourish.

The Sustainability Index ranks countries on excess carbon emissions compared with the 2030 target. This provides a convenient and available proxy for a country's contribution to sustainability in future.

The report noted that under realistic assumptions about possible trajectories towards sustainable greenhouse gas emissions, models predict that global carbon emissions need to be reduced from 39·7 giga­ tonnes to 22·8 gigatonnes per year by 2030 to maintain even a 66 per cent chance of keeping global warming below 1·5°C.

It said that the world's survival depended on children being able to flourish, but no country is doing enough to give them a sustainable future.

"No country in the world is currently providing the conditions we need to support every child to grow up and have a healthy future," said Anthony Costello, Professor of Global Health and Sustainability at University College London, one of the lead authors of the report.

"Especially, they're under immediate threat from climate change and from commercial marketing, which has grown hugely in the last decade," said Costello – former WHO Director of Mother, Child and Adolescent health.

Norway leads the table for survival, health, education and nutrition rates - followed by South Korea and the Netherlands. Central African Republic, Chad and Somalia come at the bottom.

However, when taking into account per capita CO2 emissions, these top countries trail behind, with Norway 156th, the Republic of Korea 166th and the Netherlands 160th.

Each of the three emits 210 per cent more CO2 per capita than their 2030 target, the data shows, while the US, Australia, and Saudi Arabia are among the 10 worst emitters. The lowest emitters are Burundi, Chad and Somalia.

According to the report, the only countries on track to beat CO2 emission per capita targets by 2030, while also performing fairly – within the top 70 – on child flourishing measures are: Albania, Armenia, Grenada, Jordan, Moldova, Sri Lanka, Tunisia, Uruguay and Vietnam.

"More than 2 billion people live in countries where development is hampered by humanitarian crises, conflicts, and natural disasters, problems increasingly linked with climate change," said Minister Awa Coll-Seck from Senegal, Co-Chair of the commission.

The report also highlights the distinct threat posed to children from harmful marketing.

Evidence suggests that children in some countries see as many as 30,000 advertisements on television alone in a single year, while youth exposure to vaping (e-cigarettes) advertisements increased by more than 250 per cent in the US over two years, reaching more than 24 million young people.

Studies in Australia, Canada, Mexico, New Zealand and the US – among many others – have shown that self-regulation has not hampered commercial ability to advertise to children.

Children's exposure to commercial marketing of junk food and sugary beverages is associated with purchase of unhealthy foods and overweight and obesity, linking predatory marketing to the alarming rise in childhood obesity, it said.

The number of obese children and adolescents increased from 11 million in 1975 to 124 million in 2016 – an 11-fold increase, with dire individual and societal costs, the report said.

To protect children, the authors call for a new global movement driven by and for children.

Specific recommendations include stopping CO2 emissions with the utmost urgency, to ensure children have a future on this planet; placing children and adolescents at the centre of global efforts to achieve sustainable development, the report said.

New policies and investment in all sectors to work towards child health and rights; incorporating children's voices into policy decisions and tightening national regulation of harmful commercial marketing, supported by a new Optional Protocol to the UN Convention on the Rights of the Child, it said.
