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, Jan 5: Against the backdrop of Mangalore violence of December 19, Additional Director General of Police of Karnataka Amar Kumar Pandey visited the city and held a meeting with senior police officers.

According to senior police officials here on Sunday, Dakshina Kannada and Udupi District Muslim Central Committee had planned to hold a protest against CAA at Nehru Maidan while the SKSSF had called for anti-CAA protest at State Bank area.

Though both the protests had been called off, there was an apprehension of a repeat incident of December 19 violence and hence the ADGP visited the city at the behest of state government and monitored the situation here for the entire day on Saturday.

The ADGP was unhappy that despite initial inputs and the imposition of Section 144 in the city, the situation on that day escalated to a level where police had to resort to firing only in this city.

Bengaluru, May 8: Karnataka Chief Minister B S Yediyurappa said his government is clear in its stand on extending every possible help to the farmers. The Chief Minister spoke to the farmer-leaders of the state, who wanted their concerns to be heard and addressed, with regard to the problems the agrarian community has been facing in the wake of the COVID-19 lockdown.

"We will soon make our position clear on supporting the farmers. We will not allow any hindrance to come in the way of agriculture activities," Yediyurappa told the farmer- leaders.

The Chief Minister told the delegation that the pre-monsoon activities are in full swing in the state.

The government has also set up help centres and been providing agriculture equipment on rent, the Chief Minister said. In most of the places, at least 80 per cent of the standing crops have been harvested.

Arrangements have been made to bring equipment from neighbouring states to harvest the standing crop, he said.

Yediyurappa said fertilisers and seeds are available in abundance in the state.

He informed the farmer-leaders about the arrangements made to transport flowers, vegetables and fruits to other states.

Similarly, the market has been developed for the farmers to sell their products, said the Chief Minister.

He said the government is working out a compensation for farmers who lost their crops due to hailstorm in Raichur, Koppal and Ballari. Agriculture Minister B C Patil, Horticulture Minister Narayana Gowda, Revenue Minister R Ashoka, Chief Secretary T M Vijay Bhaskar and Development Commissioner Vandita Sharma were also present in the meeting.
