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 28: Brace for hefty traffic penalties as the state government is all set to reverse a notification on revised fines which came into effect last September following pushback from road users and opposition parties.

The Karnataka government will implement traffic penalties as stipulated in the amended Motor Vehicles Act, 2019, in a phased manner following a diktat from the Centre. The government did not specify the timeline for it.

“At a recent meeting of transport ministers from various states, the Union government explained why it wanted to implement these huge fines. We found it convincing and will implement it in its original form,” said transport minister Laxman Savadi on Monday.

Savadi said India’s image globally has taken a beating due to the high number of road deaths and the Centre wants to change it at any cost. However, he said the entire set of hefty fines would not be reintroduced all at once.

BJP govt revised rates in Sept

The BJP government last September had revised fines on compoundable offences and those which are fined on the spot by traffic cops by 50%- 80%, barring drunken driving and racing.

As per the revised rates, helmetless riding attracted a penalty of Rs 500 against Rs 1,000 notified by the Centre. Driving without a licence attracted a fine of Rs 1,000 for

two- and three-wheelers and Rs 2,000 for light motor vehicles as against the earlier Rs 5,000 for all types of vehicles.

The central government recently told states and Union Territories they should enforce fines as per the amended Act and they cannot be rolled back. The road transport and highways ministry said fines cannot be reduced below the minimum amount fixed by law, unless the President gives his assent.
