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?

Kalaburagi, Feb 16: Fourteen years of life in jail has not deterred Subhash Patil from fulfilling his dream of becoming a doctor.

The 40-year-old man from Afzalpura in Karnataka's Kalaburagi was put behind bars in a murder case while doing MBBS in 1997.

Speaking to media, Patil said, "I joined MBBS in 1997. But, I was jailed in a murder case in 2002. I worked at the jail's OPD and was released in 2016 for good conduct. I completed my MBBS in 2019."

Earlier this month, Patil completed a one-year mandatory internship for getting the MBBS course degree.

Police arrested Patil in 2002 in a murder case when he was in his third year of MBBS course. A court sentenced him to life imprisonment in 2006.

He was put behind bars but he did not give up his childhood dream of becoming a doctor.

In 2016, police released Patil on Independence day for his good conduct.
