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.
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.

I'm building a 1story house with slab on load bearing walls instead of the concrete frame structure. Will this be resistant agaianst earthquakes?
