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, Apr 21: The Karnataka Government may spare its employees from salary cuts this month despite severe resources crunch it faces following steep fall in revenue collection due to the ongoing lockdown to fight the coronavirus, official sources said on Tuesday.

As of now, there is no problem with April salary and we can manage. But if May also turns out to be a wash-out (in terms of revenue collection), then the situation is going to be very tough, a senior Minister said.

Ministers and members of Karnataka Legislature are taking a 30 per cent pay-cut for a year from April 1 this year. Opposition Congress in the state has vehemently opposed any possible move to cut salaries of government employees.

You just cant even imagine, the Chief Minister B S Yediyurappa had told news agency in an interview earlier this month on the economic impact of the lock-down on the state's finances. Yediyurappa had also said that the government is now not in a position to implement Budget proposals, barring important ones, with all kinds of revenue collections having completely stopped following the lockdown.

The government recently said it proposes to regularise unauthorised properties in the state by imposing penalty, and also auction more than 12,000 corner sites belonging to the Bengaluru Development Authority, as part of resource mobilisation drive.
