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, May 9: A team of doctors at Mangaluru's Mangala Hospital has developed a 'bubble helmet' that will provide an alternative to patients who need an oxygen mask.

The team was led by Dr Ganapathi, medical director of Mangala Hospital and Mangala Kidney Foundation in the city.

The bubble helmet, which has a special collar attached to it, helps the patients with breathing issues, and to avoid using ventilator facility.

Dr Ganapathi said, "When a patient needs intubation we will be providing them oxygen bubble helmets and we will first give it a trial before we intubate a patient."

"I have converted an ordinary snorkelling mask into a ventilator assist device, this mask can be used as a personal protection device by connecting it to a bacterial viral filter," he added.

Dr Ganapathi said that the connector has been made available in India and a snorkelling mask can be easily converted into a ventilator assist device. And it will make the management of coronavirus patients easy.
