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?

The committee said: "COVID-19 and non-COVID-19 patients should be segregated and online health services should be encouraged. Restrictions should be minimised in districts where there is nil or minimum cases of COVID-19 and lockdown should be continued in hotspot areas with quarantine measures strictly being implemented."

With regards to the testing of likely patient, the committee informed that rapid test kits would help to quarantine more likely patient. "The rapid test kits will arrive in April 12. These kits will boost our facility and would help us in quarantining the more people."

On the subject of lifting transportation ban, the committee suggested that the transport of goods and services must continue but with regards to passenger carriers, they are suspended till April 30.

"Goods and Transportation should be allowed, but passenger carriers should be banned until further orders. No buses, trains nor flights will be plying till April 30. No metro trains and auto-rickshaws should be allowed and an odd-even system transport system should be implemented," the committee added.

The committee also suggested that all industries, IT, BT and Garments should be made to work on 50 per cent strength. Garments workers should be allowed to stitch PPEs, which are in more demand. And for construction workers, the committee suggested that they should be allowed to work at sites at 50 per cent strength.

They suggested that educational institutions remain closed till May 30 and online classes must be encouraged.

Dr. Devi Shetty heads the Taskforce and Dr. C. N. Majunath, Dr. Nagaraj, Dr. Ravi and Sudharshan were also the part of the committee.

According to the Ministry of health and family welfare, 181 cases have been reported in the state so far. A total of 5,734 positive cases have been reported of which, 166 are dead and 473 are cured/discharged and migrated.

Mangaluru: The police team investigating the case of bomb planting at the international airport here on January 20, took suspect Aditya Rao to several places in the city where he had frequented in the past few months, police said on Wednesday.

Police had earlier recovered a box from his bank locker at Udupi that contained a white powder which he claimed was cyanide. The substance has been sent to the Forensic Science laboratory for confirmation.

On further interrogation, Rao told police that he had a locker in a bank in Mangaluru also, where he was taken. Only some papers were seen in the locker, police said. He was also taken to the room where he stayed while he was working at a hotel in Balmatta here and to a hardware workshop from where he had purchased some spare parts, they said.

A 'live' explosive device was found in an unattended bag near a ticket counter of the departure gate of the airport here on January 20, triggering a scare before it was defused at a nearby open ground.

Police had released a picture of a man captured on CCTV camera as the suspect who placed the bomb and Rao later surrendered. Meanwhile, sources said the airport authorities got an anonymous call on Monday evening that a bomb had been planted in the airport. After thorough search, it was found to be a hoax. City police commissioner P S Harsha has warned of stringent action against those who make such calls.
