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.

Bengaluru, Mar 11: Heated verbal exchange between Minister K Sudhakar and former Speaker K R Ramesh Kumar in the assembly over disqualification of 17 MLAs last year, continued to disrupt the proceedings on Wednesday, with both opposition and treasury benches pushing for a privilege motion and demanding action.

Chaotic scenes and adjournments marked the House proceedings, with both sides not ready to budge.

As the House met for the day, around 11 am, senior Minister K S Eshwarappa accusing Congress MLA Ramesh Kumar of using "expletive" during a debate last evening, demanded his apology and that he be kept out of the proceedings.

Sudhakar, against whom expletive was allegedly used by Kumar, said, the words used were unpardonable and he should be heard, as he has given notice.

Leader of Opposition Siddaramaiah then demanded that he be allowed to speak first as he had given notice on Tuesday itself.

The Congress leader on his part has accused Sudhakar of breaching Kumar's privilege by allegedly making derogatory remarks against him.

Intervening, Speaker Vishweshwar Hegde Kageri said he has received breach of privilege notice from both sides and would allow it only after the question hour as per rules.

Though Congress expressed its agreement with the Speaker about letting them raise the matter after question hour, BJP legislators including Ministers said, Ramesh Kumar should be suspended.

Pointing out that Kumar was not inside the House, some ruling party MLAs even called him "escapist" and demanded action against him.

Strongly objecting to it, Siddaramaiah questioned the ruling party's intentions in running the house smoothly.

As this was followed by heated arguments between both sides, the Speaker adjourned the House for 15 minutes.

When the house met after much delay at 12:55 pm, the chaos continued.

As the Speaker allowed Minister Jagadish Shettar to speak, who was requesting permission to raise a point, Siddaramaiah objected to it and said he had given notice first.

He said, "this is not correct, it looks like government doesn't want the House to function, they don't want discussion on the budget, they are purposely blocking the proceedings of the House".

However, some BJP MLAs reacted to this by shouting slogans "shame shame Ramesh Kumar".

As his repeated attempts to conduct the proceedings failed, the Speaker adjourned the House for lunch.

Sudhakar, while speaking during a special discussion on the Constitution on Tuesday evening had made critical remarks against the decision of Kumar, as speaker, to disqualify 17 Congress-JD(S) MLAs under the anti-defection law, including him.

Angered by this Kumar, who opposed discussion on the subject, amid heated argument between BJP and Congress members allegedly uttered the expletive, which aggravated the situation and had resulted in pandemonium in the House last evening.
