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?

Mangaluru, Jul 26: Rubbishing reports about cancellation of institutional quarantine for international passengers in Mangaluru, local health authorities have clarified that 14 day isolation including first seven day institutional quarantine must for international passengers. 

For past couple of days rumours were doing rounds on social media that the government has done away with quarantine for international passengers. A few Mangaluru-based news portals also had published it as news without quoting any reliable sources. 

Meanwhile, district health officer in his clarification message said that neither Karnataka government nor Dakshina Kannada district administrant has revised the quarantine norms for international passengers. 

“Those who arrive from overseas must remain in isolation for 14 days. Out of this, seven days have to be spent in institutional quarantine (in hotel or lodge). During this period, the throat swab sample of the person will be sent for covid-19 testing. If the report is negative, then they will be sent to home quarantine for another seven days."

He said that concession in terms of number of days has only been given for people with other health conditions, children and the elderly. "For children below 10 years, pregnant women, elderly above the age of 60 years and other with other ailments, the throat swab will be collected on the second day of institutional quarantine. If the report turns negative, they will be sent to home quarantine for 14 days."

Bengaluru, May 30: People travelling to Bengaluru by flight or train must pay to get their Covid-19 tests done at designated private labs.

This is being done to improve the participation of private labs that have been approved by the Indian Council of Medical Research to do testing. Many of these labs are running at sub-optimal levels.

The new rule will also help the special categories of passengers and their attendants to leave early for home quarantine after giving the sample once the swab collection centres are established at airports and railway stations. The nodal officers at these places will coordinate in establishing the swab collection centres.

Each test will cost Rs 650 per sample. XCyton Diagnostics will cater to air passengers. Rail passengers will be tested at Neuberg Anand Reference Laboratory, Cancyte Technologies Pvt Ltd, Aster Labs, Narayana Hrudayalaya, Vydehi Hospital and Syngene International Ltd.
