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?

Bengaluru, Jul 14: The Karnataka government on Tuesday made changes to the Land Reforms Act 1961 through an ordinance to allow non-agriculturists to buy and own farmland for farming.

“The Land Reforms Act has been amended through an ordinance and notified after Governor Vajubhai R Vala gave his assent to it on Monday night,” a Revenue Department official told media persons.

It now permits non-farmers to buy farmland and grow food crops. But they can’t use it for other activities.

“Sections 79 A, B and C of the Act have been repealed, paving way for bona fide citizens to invest in farmland and take to farming as a hobby, passion or additional occupation, which is rewarding,” the official said.

The amended Act will enable the state to attract investment in the farm sector and boost food output. The farm sector’s contribution to the state’s gross domestic product (GDP) has been less than the manufacturing and services sectors over the last two decades.

Criticism by farmers, the Congress and the JD(S) since the cabinet approved changes on June 11 forced the state government to retain section 80 of the Act, with an amendment, to prevent sale of dam water irrigated farmland.

“The ordinance has also added a new section (80A), which says relaxations under the Act will not apply to land given to farmers under the Karnataka SC and ST (Scheduled Caste and Tribe) Act 1978,” the official said.

The changes permit mortgage of farmland only to the state-run institutions, firms and cooperative societies specified in the Act. The ordinance also makes legal cases pending in courts against the sections amended redundant as the new Act addresses the concerns raised in them.

“Besides generating substantial revenue for the state government, the Act will now allow farmers who find the occupation non-remunerative and risky due to droughts/floods and labour shortage to sell their surplus land to urban buyers,” the official said.

Ruling BJP Rajya Sabha member KC Ramamurthy from Bengaluru said the amended Act would allow any citizen to buy farmland.

“Though hundreds of people petitioned successive governments for the past 45 years to abolish the ‘draconian’ sections, they were ignored. I compliment Chief Minister BS Yediyurappa and Revenue Minister R Ashoka for the decision to allow everyone to buy farmland irrespective of their occupation or profession,” Ramamurthy told media persons.

Bengaluru, Jan 12: Karnataka’s ranking in Niti Aayog’s sustainable development goals (SDG) index rose by one place to No. 6 in 2019, compared to the year before.

Of the 17 SDGs that are used to compute the overall index, Karnataka topped in two – ‘climate action’ and ‘life on water’. The former is a measure of how well a state integrates climate action into policies and strategies and promote mechanisms for raising capacity for effective climate change planning and management. The latter focuses on preventing marine pollution, ending illegal and destructive fishing practices, and sustainably managing and protecting marine and coastal ecosystems.

It also did well in ‘decent work and economic growth’ and ‘peace, justice and strong institutions’. But it fared poorly, slipping 16 places – from No. 5 in 2018 to No. 21 in 2019 – in ‘industry, innovation and infrastructure’. Rankings in ‘quality education’ and ‘zero hunger’ have also fallen. While in education it is now ranked 7, a drop of three places, in ‘zero hunger’, it has dropped to No. 17 from 13. SDG is a United Nations initiative. Niti Aayog has customised it for India, and 36 states and union territories are ranked. The organisation admits there is an issue of data availability in India, indicating the numbers may not exactly reflect the ground situation.

In ‘industry, innovation and infrastructure, Karnataka scored just 40 out of a target of 100. The country average was 65. It failed to achieve targets in all the four parameters for the category, except in the number of mobile connections, where it has 100 connections per 100 population. The biggest dip was in manufacturing industry jobs and in providing allweather roads under Pradhan Mantri Gram Sadak Yojana to targeted habitats. Niti Ayog has given a score of 0 for the latter. Speaking on the dismal performance in the ‘industry and infrastructure’ category, state planning commission vice-chairman BJ Puttaswamy said he was yet to look into this parameter. “I have asked the departments concerned to meet me by Monday,” he said.
