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, Feb 8: The BJP on Saturday drew flak on Twitter for taking a swipe at Muslim women who appear to be standing in a line to vote in Delhi's assembly polls. ""Kaagaz Nahi Dikayenge Hum" ! ! ! Keep the documents safe, you will need to show them again during NPR exercise (sic)," the party's Karnataka Twitter handle posted using the hashtag #DelhiPolls2020. 

The video, which appears to have been taken from one of the polling booths in Delhi on Saturday, shows burqa-clad women flashing their voter ID cards. While the threatening tone of the tweet is unmissable, the tweet contradicts the government's statement that no person needs to submit any documents during the house-to-house survey for updating the National Population Register (NPR) and that information provided by individuals would be accepted and recorded. 

The tweet has added to the prevailing confusion regarding the NPR exercise in the country. 

The NPR is a list of "usual residents" of the country. In 2010, the data for NPR was collected along with the house-listing phase of the Census of India 2011. The data was updated in 2015 by conducting a door-to-door survey.

Currently, it has been decided to update the NPR along with the house-listing phase of Census 2021 during April to September 2020 in all the states/union territories except Assam.

Most of the opposition parties see NPR as a prelude to the contentious National Register of Citizens (NRC), which has been opposed by even NDA allies like the JD(U). The NPR questionnaire asked details like the birthplace of parents. In combination with the recently amended citizenship law, protesters fear that the registry might be eventually used for NRC. 

As a result, people, predominantly Muslims, have hit the streets as India witnesses one of the most widespread civilian unrest of recent times.

Bengaluru, Mar 19: Karnataka High Court on Wednesday rejected the plea by Congress leader Digvijay Singh seeking directions to the police to allow him to meet rebel Madhya Pradesh Congress MLAs who are lodged in Bengaluru.

Earlier in the day, Singh said at a press conference, "I have filed a plea in the Karnataka High Court, seeking permission to meet Madhya Pradesh Congress MLAs who are putting up at Bengaluru. I have decided to be on fast and shall take a call on that after the decision of the Supreme Court and the High Court," Singh said at a press conference here earlier.

Singh said, "The BJP is busy in toppling duly-elected governments. We had successfully thwarted their plans to destabilise the MP government but we were let down by Jyotiraditya Scindia who had a very successful career in Congress."

"We never expected that he would ditch us and join hands with the BJP," he added.

The Congress leader also said that the BJP government had become insecure since the Kamal Nath-led government started tightening the laws on mining.

"Chief Minister Kamal Nath drafted a new mining policy for the sand under which the mines were allotted through auction. All this was unpalatable to the BJP and from Day 1 they started offering money to our Congress legislators," he said.

"In BJP, the Atal Bihari Vajpayee's kind of leadership no longer exists. The leadership which controls the BJP now includes people who have joined hands to do all kinds of unscrupulous things which has led to a stage in India where the banks are collapsing, non-performing assets and unemployment are growing," he added.

Earlier today, he was put under preventive arrest after he sat on a dharna near Ramada Hotel here allegedly for not being allowed to meet the 21 rebel Congress MLAs lodged in the hotel.
