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?

Bengaluru, Jan 30: A kidnap case in Bengaluru has proved that crime-based series on TV channels can inspire youth to commit crimes. 21-year-old Chirag R Mehta, who kidnapped a schoolboy and got arrested within an hour after demanding Rs 5 lakh ransom, has told police that he thought of abducting the boy after watching Crime Patrol, a popular Hindi crime anthology series created by Subramanian S. lyer for Sony TV. The kidnapped schoolboy was rescued by the police and reunited with his parents. Son of a gift shop owner from Basavanagudi area in Bengaluru, Chirag has reportedly told police that decided to make some quick money to spend on cricket betting and gambling after learning kidnap tricks from the ‘Crime Patrol’. According to police, Chirag reached a private school around 3pm on Tuesday on a Bounce rental bike and zeroed in on a fourth standard student who was walking out of school. He told the boy he was his father's friend and that he required help to search for a relative who had gone missing. The boy believed Chirag and rode pillion on the bike. Chirag then engaged the boy in conversation and learnt about his father's business and got his mobile phone number. He then made a call to the boy's father, demanded Rs 5 lakh and warned him against approaching cops. However, the boy's father alerted Cottonpet police and special teams were formed to crack the case. While Cottonpet inspector Venkatesh TC's squad verified CCTV footage in and around the school, Chamarajpet inspector BG Kumaraswamy's team started tracking the suspect's mobile phone movements. An hour later, the suspect's location was traced to a hotel on the Lavelle Road-St Mark's Road stretch. Police rushed there, rescued the boy and arrested Chirag.

Bengaluru, Jan 2: Accusing Prime Minister Narendra Modi of "neglecting" Karnataka ahead of his visit on Thursday, the state Congress questioned why he did not give adequate relief and pay a visit to the state, when most of its parts were affected by severe floods last year.

Modi will begin his two-day visit to the state on Thursday afternoon.

The Congress' Karnataka unit in a series of tweets also questioned the Prime Minister about not conferring the "Bharat Ratna" on Shivakumara Swamiji of Siddaganga Math, who passed away last year at the age of 111 years.

"Why you did not visit the state, when it was affected by floods? Despite the damage of over Rs 1 lakh crore why you did not declare it as a national disaster? Why you did not give interim relief? When the state government has given a report that the damage caused was to the tune of Rs 35,300 crore why did you sit quiet by giving just Rs 1,200 crore," the state Congress tweeted.

As many as 103 taluks in 22 districts of Karnataka were affected due to unprecedented floods in August, in which over 80 people were killed.

Around seven lakh people were shifted to safe areas during the deluge and thousands of houses were damaged.

In October, various parts of the state faced a deluge for the second time in two months, killing over 13 people and damaging thousands of houses.

Asking as to why the Centre was not giving the state's share of GST amount adequately, the Congress questioned as to why dues under MNREGA programme were not paid so far, and why Karnataka was being neglected while allocating grants.

Questioning Modi as to why he did not visit Tumakuru when Shivakumara Swamiji of Siddaganga Math passed away, the principal opposition party in the state Assembly, also sought to know why the seer was not conferred with the Bharat Ratna yet.

It also pointed out that former Chief Minister Siddaramaiah had written a letter in this regard in January 2018.

The Congress has also hit out at the BJP-led Central government over imposition of Hindi language by neglecting regional languages and mother tongue.

The Prime Minister will kickstart his visit to the state by paying tributes to the late pontiff's 'Gadduge' (final resting place) at the Math premises near Tumakuru.

Later, he will attend an event organised to give away Krishi Karman awards and to distribute fishing equipment at the government college ground in Tumakuru, before leaving for Bengaluru where he will be attending a DRDO event.

On Friday he will be inaugurating 107th Indian Science Congress here.
