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.

Mangaluru, May 22: Following requests from Kannadiga entrepreneurs in Kingdom of Saudi Arabia and persistant efforts of former deputy chairperson of the NRI Forum of Karnataka government Dr Arathi Krishna, the government of India has finally approved the repatriation of stranded Indian expatriate workers amidst prolonged covid-19 lockdown through chartered flights arranged by their employing companies particularly in Gulf region and elsewhere. 

The government has also issued a Standard Operation Protocol (SOP) to be followed to be followed by those who hire the flights. The government's nod will not only allow repatriation of larger number of citizens, who are on wait-lists, but also allows private airlines to get their aircraft, crew, and operational staff actively working again in preparation for resumption of scheduled flights. 

Zakaria Jokatte, CEO of Al-Muzain Est. and K S Sheik, Director of Operations at Expertise Contracting Co. Ltd - both Mangalurean entrepreneurs in Saudi Arabia - were among those who had sought permission to hire chartered flights for the immediate repatriation of their hundreds of employees. 

The NRI entrepreneurs in Gulf have thanked Dr Arathi Krishna for continuously persuading the authorities concerned to issue green signal for the operation of chartered flight at a time when there were only a few scheduled flights under Vande Bharat Mission. 

Welcoming the move Dr Arathi Krishna told coastaldigst.com that Indians stranded in any foreign country can utilize this facility. "Initially, I was approached by Mr Zakaria and Mr Sheik who wanted chartered flights to help their employees fly back to India. I asked them to write to the Indian Ambassador in Saudi Araia Mr Ausaf Sayeed. Then I requested the ambassador to forward the request to Joint Secretary Dr Nagendra Prasad, who is in charge of gulf division in the Ministry of External Affairs, and then to Secretary on charge of Gulf and then I requested Secretary of Economic Relations Mr T S Tirumurti who was also in charge of Gulf to follow this up," she said. 

"There were similar requests for chartered flights from African countries too. Then I persisted officers constantly to take it up to the Foreign Secretary Harsh Vardhan Shringla and Civil Aviation Minister Hardeep Singh Puri and now all the people requesting this from Saudi Arabia have got confirmation from the ministry and communicated by embassy to those who had requested for the chartered flights," she said.
