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?

This includes five deaths, Inspector General of Police and Additional Commissioner of Police (Administration) Hemant Nimbalkar told media persons.

He said as of Thursday, 190 have been cured while 200 are under treatment. Twenty police stations have been sealed, he added.

He claimed the Bengaluru police has suffered the most compared to any department, organisation or institution because the force is deployed in the field and dealing with the situation.

The infection among police is highest despite training being given to them on how to protect themselves from the coronavirus.

According to him, every morning duty charter is given to the police personnel where they are told how to avoid getting the infection and handle the situation if they find symptoms of coronavirus.

"Despite taking all the precautions, infection in our department is high because we are the ones who are on the road.

We are meeting hundreds of people whom we don't know, whether they are Covid infected or not," Nimbalkar said.

Along with the policemen, their families too are at risk of contracting the virus.

An assistant sub-inspector at VV Puram police station was the first casualty in the Bengaluru police on June 13.

A heart patient, who was on leave due to ill health, he collapsed at home and died.
