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?

Mangaluru, May 6: The Kanara Chamber of Commerce and Industry has urged the government to consider erstwhile undivided Dakshina Kannada (now DK & Udupi) as one unit for the purpose of movement of people. KCCI president Isaac Vas has written a letter to Karnataka chief secretary T M Vijay Bhaskar in this regard. 

Mr Vas said: Even though the erstwhile Dakshina Kannada district was bifurcated in 1997 for administration purposes, the two districts are actually an urban agglomeration with most of the population residing in suburbs/towns. Office Staff, technical crew and labour of many industries reside in either district and commute daily for work within an efficient transport system.

The present restriction on Inter-district movement in view of the Lockdown is hindering the kick starting of industries and commerce. Workers are deprived of their livelihood and Industry and business owners are finding it challenging to move forward. To add to this, the migrant labour is moving back to their native places further aggravating the situation. Many Industries and Commercial establishments have requested us to take up this matter with the government, he said.

“Hence, we kindly request you to consider these two districts as one geographical area for the movement of people and private vehicles,” he said adding that this would facilitate movement of people for employment and business in either districts of Dakshina Kannada & Udupi.

He pointed out that Bangalore Rural, Bangalore Urban, Ramanagara, Chikkaballapur and Kolar are considered as a single unit as per your order No. RD158/TNR 2020 dt 03/05/2020 (Clause 2(a)).
