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?

Panaji, Feb 6: Goa Chief Minister Pramod Sawant on Wednesday told the Legislative Assembly that neighbouring Karnataka has diverted the Mahadayi river water, due to which its flow in the state has taken a hit.

He was speaking during a debate on the motion of thanks to Governor Satya Pal Malik for his address.

Goa and Karnataka are locked in a dispute over sharing of the Mahadayi river water. Goa is strongly opposing the Kalasa Banduri project proposed to be built by Karnataka on the river, which is aimed at providing drinking water to three north Karnataka districts by diverting the Mahadayi water into the Malaprabha river.

Speaking in the House, Sawant said that the flow of Mahadayi river has reduced due to the diversion of water by Karnataka.

"I am admitting that they (Karnataka) have diverted the water. We have brought it to the notice of the Union Ministry of Environment, Forest and Climate Change," he said.

The Goa government has explained to the Centre that the water which flows into the state is "not wasted".

"We have told them that the perennial flow of water is necessary for Goa's wildlife," he said.

Sawant said that his government was serious on the issue of Mahadayi.

"Mahadayi is more than a mother to me. We have not compromised anywhere on the issue. I have been associated with the Mahadayi agitation since 2000," the chief minister said.

He said the issue would be fought before the Supreme Court, where special leave petition has been filed by the state.
