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, May 2: Former chief minister and Congress leader Siddaramaiah have urged the state government to arrange free-transport facilities to those stranded labourers and their family members to return their native places.

In a statement issued here on Friday, the former chief minister criticised the State Government for having decided to collect bur fare from them, ''three-times more than the regular fare''.

Stating that the migrant labourers, who had been stranded ever since lockdown had been clamped in the entire country are not in a position to pay for their travel, Siddaramaiah urged the state government to treat them with human face.

Bengaluru, Jul 2: Senior Congress leader Mallikarjun Kharge said that the "RSS needs to be defeated to save the country" and Prime Minister Narendra Modi and Union Home Minister Amit Shah are "destroying the nation".

Kharge was speaking at a KPCC program where DK Shivakumar took charge as state Congress president.

He said that the Prime Minister and the Home Minister are not ready to take accountability for any issues including China, and are instead blaming Rajiv Gandhi Foundation of getting funds from China.

"Rajiv Gandhi foundation utilized funds for the development of the nation and for the betterment of the downtrodden people," Kharge said.

"Prime Minister Modi and Shah both are destroying the economy of the nation, and their policies and plans are the reason for increasing COVID-19 situation in India," he said.

"Prime Minister and Amit Shah never listen to Opposition parties, instead they plan something and their policies are the reason for MSME losses and job losses in the country," he added.

The Karnataka BJP, which faced action on Twitter earlier this month over incendiary tweets, this time has passed the blame of Sangh Parivar sponsored Delhi violence to the victims.

In an insensitive tweet on Friday, it dubbed the protests against the notorious Citizenship Amendment Act (CAA) as "fake" and added that the violence that followed was "the most well-planned assault on the Idea of India," in an apparent attempt to portray the victims as villains.

The handle, notorious for tweets targeting Muslims, blamed the clashes that erupted in Delhi between people demonstrating for and against the CAA on "so called 'Peacefuls'" - a known right-wing slur for Muslims.

Many people on social media called out the tweet for misleading people and covering up the role of Delhi BJP leader Kapil Mishra's provocative speech for triggering the violence or the failure of the Delhi Police, which reports to the former BJP chief and Union Home Minister Amit Shah, in controlling the riots.

Earlier this month, the Karnataka BJP had tweeted a video of Muslim women standing in queue to vote in the Delhi elections, showing their voter ID cards, with the snarky caption: "Keep the documents safe, you will need to show them again during NPR (National Population Register) exercise."

Soon after, the party unit's Twitter handle was blocked by the social media platform for 24 hours after many accused it of encouraging Islamophobia.

NPR has been widely criticised by opposition parties as a precursor to the government's planned NRC or National Register of Citizens which intends to make Indians prove their citizenship with documents that many poor or illiterate do not possess.

Many fear that combined with the already imposed CAA - which promises citizenship to only non-Muslim refugees from Pakistan, Afghanistan and Bangladesh - the NRC can be used to make millions of Muslims stateless.

The government has denied the allegation and said the CAA only intends to help those who have faced religious persecution. In recent weeks, it has gone back on its rhetoric on the NRC which was announced by Amit Shah in parliament as "it will certainly happen".

The CAA, which was cleared by parliament in December, has triggered deadly protests in the country which left at least 25 dead till Sunday. Since then, at least 42 more people have been killed as large-scale violence erupted in northeast Delhi and hundreds of homes and shops have been burned to the ground.
