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, May 6: More than a month after international flights have been barred, Karnataka government is preparing to quarantine all 10,823 of the state''s people poised to return home from overseas amid the Covid pandemic, an official said on Tuesday.

"The state has planned to quarantine all 10,823 passengers coming back to Karnataka. The quarantine guidelines framed as below would be applicable," said Health Commissioner Pankaj Kumar Pandey in a statement.

According to the Government of India, 10,823 Karnataka residents have been stranded abroad by April 30, comprising 4,408 tourists, 3,074 students, 2,784 migrants and professionals and 557 ship crew.

Out of the 10,823 people, the state government is expecting 6,100 to return early as the government has decided to allow Indians stuck abroad to return.

"All the passengers arriving at points of entry (airports and seaports) will be compulsorily screened for symptoms of Covid-19," said Pandey.

Point of entry screening will include self-reporting form verification, thermal screening, pulse oximeter reading, briefing with instructions, categorisation, stamping for some and downloading of Aarogya Setu, Quarantine Watch and Apthamitra apps.

Arriving passengers are also required to declare existing comorbidities such hypertension, diabetes, asthma or any lung disease, organ transplantations, cancer, tuberculosis and other ailments.

Passengers will be categorised into three groups: Category A (symptomatic on arrival), Category B (asymptomatic with co-morbidity or aged above 60 years) and Category C (rest of asymptomatic passengers).

Depending on the category into which the people fall, their quarantine place and time will be determined.

Category A arrivals will be subjected to institutional quarantine for a fortnight, Category B one week quarantine at a hotel or hostel, followed by another week at home, and Category C home quarantine for a fortnight.

Karnataka government is making elaborate arrangements and logistical means, deploying healthcare, police and several other departments into action to handle the huge influx of Kannadigas and state residents.

Pandey has issued a 21-page elaborate standard operating procedure (SOP) guidelines on how to face the international returnees.

Bengaluru, Jan 13: RSS leader Kalladka Prabhakar Bhat on Monday held a protest march at Ramnagar district’s 
Kapalabetta under the aegis of Hindu Jagran Vedike’s ‘Kanakapura Chalo’ campaign against the construction of the world’s largest Jesus statue there.

Hundreds of protesters of the Vedike staged a protest march in the city starting from the Kanakapura Ayyappaswamy temple.

“We are not here to disturb the peace. We have met each other at the wedding of Sriramulu’s daughter. So you know who I am, DK Shivakumar. How long will you continue with these lies? Is the intention behind the statue of Jesus to solidify your vote bank? Build the statue in America or England, we will not allow it here,” said the RSS leader as the keynote speaker at the rally.

Bengaluru, May 17: Left to itself, Karnataka will look to spring back towards normalcy under Lockdown 4.0 as the state government is on standby to resume public transport services from May 18, if the Centre allows it. 

Though KSRTC and BMTC have been preparing for resumption of services, officials in the two corporations told DH that they cannot make a move till the government makes a decision.

Transport Commissioner N Shivakumar said the department will take a decision based on the state government's orders. "The government will take a call on buses as well as taxi and other transport services," he said.

Senior officials in the state government said Deputy Chief Minister and Transport Minister Laxman Savadi has written to Union Minister for Road Transport and Highways Nitin Gadkari seeking a nod for resumption of the services. 

Transport Secretary Gaurav Gupta has written a separate letter to his counterpart in the Union government requesting permission to operate public transport. "The state government wants the services to open. The official has listed out the steps the corporations will take to ensure social distancing other steps that will be taken to check spread of Coronavirus," a source said.

The B S Yediyurappa administration has been bullish on easing lockdown restrictions. 

If the Centre empowers the states to define Lockdown 4.0, Karnataka is likely to do away with the red-orange-green zoning of districts and allow public services to resume, except in COVID-19 containment zones. The government is also likely to redefine its containment strategy by micromanaging localities where COVID-19 cases are reported, without letting life in an entire district get affected. 

The government has already shown willingness to allow hotels and gyms to open after May 17 subject to social distancing norms and restrictions. In fact, the government has proposed to allow the resumption of all economic activities in standalone establishments. The government, however, is not keen on opening malls, theatres, diners and establishments that have centralized air conditioning. 

“Everything depends on the Centre,” Deputy Chief Minister CN Ashwath Narayan said. “Our only stand is that the red zone should be treated at par with the other zone when it comes to relaxation.”
