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?

Hassan, Mar 13: In what could have been a major tragedy, an under construction flyover across Hassan-Mangaluru railway level crossing, near the new KSRTC Bus stand here collapsed today.

Fortunately no casualties occurred despite six concrete beems of 50 feet height, collapsed and broke into pieces.

The much awaited project was completely neglected by the successive governments for over a decade due to politics.  It was sanctioned eight months ago.

The Rs 42 crore project was taken up by a joint venture between state, center and South Eastern railway. The contractor or the Engineer were not present when the incident occurred.

Blaming the contractor, the locals alleged that poor quality of work led to the incident. No contractor or engineer was present even during construction, they added. Siddaiah, who runs an eatery near KSRTC bus stand said that it could have been a major tragedy if people were underneath the flyover when it crashed. The incident should be probe and the contractor should be punished, he added.

Chitradurga, Feb 10: President of the BJP State unit Nalin Kumar Kateel on Sunday hit out at Congress leader M. Mallikarjun Kharge for allegedly likening Prime Minister Narendra Modi to a “zero candle bulb”.

Mr. Kateel told reporters here that Mr. Modi was a “1,000 watt bulb that gave light to the world”, and compared Mr. Kharge to a lamp that had burned out politically.

Mr. Kateel charged that Mr. Kharge had become frustrated after losing the elections and after his party did not even consider him for a Rajya Sabha seat. And this had made the Congress leader to make wild charges against the Prime Minister.

Lashing out at the Congress, Mr. Kateel alleged that the Congress was continuing the “divide and rule” policy of the British and accused the former Prime Minister H.D. Deve Gowda of being the “other face of the Congress”.

Mr. Kateel also came down on the former Chief Minister Siddaramaiah. He ridiculed the Congress for the delay in choosing a new KPCC chief after Dinesh Gundu Rao submitted his resignation.
