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, Apr 28: Trucks carrying fish loads from Kerala will not be allowed to enter Dakshina Kannada district as the authorities are not being able to control the rush in markets, state Fisheries Minister and district-in-charge Kota Srinivas Poojary said Monday.

The deputy commissioner has been instructed to restrict the entry of fish transport vehicles from outside the district forthwith, in view of the difficulty in maintaining social distancing at the markets identified in the district, the minister told reporters here.

The coastal district has to take more precautionary measures to fight COVID-19 as the number of positive cases have risen in the last couple of days, he said.

Bengaluru, May 23: The Karnataka government on Friday said returnees from six states with high COVID-19 cases will be kept in institutional quarantine for seven days.

The states are - Maharashtra, Gujarat, Delhi, Tamil Nadu, Rajasthan and Madhya Pradesh.

As per the standard operating procedure released by the government, all people to arrive via rain, air road are expected to quarantine.

After they test negative for the disease in pool testing, they will be sent for home quarantine for another seven days, the government said.

Returnees from other low prevalence states will be asked to follow 14 days of home quarantine, according to the standard operating procedure (SOP) for entry of persons from other states to Karnataka issued by the state health department late on Friday night.

However home quarantine is allowed for pregnant ladies, people above 80 years, patients with comorbidities and children below 10 years of age, along with one attendant after they test negative.

In special cases like businessmen coming for urgent work, the quarantine period will be waived if they furnish a report from an ICMR-approved laboratory showing they tested negative for COVID-19, it said.

However, if they don't have reports, they will have to stay in institutional quarantine and can leave once their results test negative.

In case their stay exceeds 5 days, they will be sent to the fever clinic and get a five-day extension if found asymptomatic.

The report should not be more than two days old from the date of travel.

All Karnataka returnees who entered from 4 May will be tested from 5-7 days from the time of their arrival.

If found COVID-19 negative, they will be sent to home quarantine and will have to follow due precautions, the SOP stated.

The Ayodhya police booked a senior journalist on Wednesday for raising questions on Uttar Pradesh Chief Minister Yogi Adityanath's visit to the Ram Janmabhoomi for a religious ceremony amid the lockdown over the novel coronavirus pandemic.

The FIR mentions a tweet by Siddharth Varadarajan, editor of news portal 'The Wire', where he said: "On the day the Tablighi Jamaat event was held, Adityanath insisted a large Ram Navami fair planned for Ayodhya from March 25 to April 2 would proceed as usual and that 'Lord Ram would protect devotees from the coronavirus."

Varadarajan had clarified in another tweet that it was "Acharya Paramhans, Hindutva stalwart and head of the official Ayodhya temple trust, who said Ram would protect devotees from coronavirus, and not Adityanath, though he allowed a public event on 25/3 in defiance of the lockdown and took part himself".

Taking the suo-motu cognizance, Faizabad Kotwali police station incharge Nitish Kumar Shrivastava registered an FIR under sections 188 (disobedience to order duly promulgated by public servant) and 505(2) (statements conducing to public mischief) of the Indian Penal Code for doing "disreputable" comment against the chief minister.
