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.

Tumakuru, Feb 5: Former Lokayukta Justice N Santhosh Hegde has questioned the integrity of the B S Yediyurappa led BJP government as it has not taken an action to abolish the Anti Corruption Bureau (ACB) to re-establish the Lokayukta in Karnataka.

Speaking after felicitating the retired scientist of NASA Gopal Iyengar at the Karnataka Public School at Kadaba in Gubbi taluk he reminded that the BJP had promised to establish the Lokayukta.

"No party will like to strengthen the Lokayukta and now BSY is also tightlipped and even put an end by appreciating that ACB has been doing a good job", he regretted.

In fact, the Lokayakuta had the power to prosecute even the top brass of officials and now the ACB cannot without the government's permission, he clarified.

He denied any remarks on the CAA and NRC but observed that the youths of the country have been misguided by the politicians as they lost their focus on education by involving in protest rallies.

"I suggest they to straight away take a political plunge instead of getting misused at the hands of the politicians with selfish motives", he said.

Bengaluru, Jul 15: With the state capital along with a few districts under lockdown to control the spread of Covid-19, Karnataka Home Minister Basavaraj Bommai on Wednesday said the measure was important to break the chain and people seem to have understood its importance.

Appealing for cooperation from the people, he asked them not to make it inevitable for police to use force in implementing the lockdown. "Traffic movement is less, there is a lockdown atmosphere everywhere, I feel that people have understood the importance... cooperation is required. I appeal to the people, if this lockdown has to be effective it has to be voluntary, only then we can control the rapid spread of coronavirus," Bommai said.

Speaking to reporters here, he said this lockdown is important, last time the infection was not up to this level. "This time areas that have a high number of infections- about five districts and Bengaluru city are going for lockdown. People have understood that this lockdown is to break the chain," he said. "Please don't make it inevitable for police to use force," he added.

Bengaluru urban and rural areas are under "complete lockdown" since last night at 8 pm and it will be effective till 5 am on July 22.

Following Bengaluru urban and rural, administrations in several districts like Dharwad, Dakshina Kannada, Kalaburagi (only in Urban areas), Bidar, Raichur (in Raichur city and Sindhanur) and Yadgir too have announced lockdown.

Noting that Police have taken all necessary strict measures to enforce lockdown in Bengaluru urban and rural districts by restricting the movement of vehicles and people, Bommai said barricades have been erected at various places and flyovers have been shut. People have been allowed to purchase vegetables and groceries till 12 noon, he said.

The government has warned of action in case of any violation of the lockdown rules.

Bengaluru, Jan 30: The BJP government of Karnataka has given green signal to the proposal of hiking milk prices by Rs 2 per litre.

The new prices will come into effect from February 1. Seeking revision of prices, the Karnataka Milk Federation (KMF) had submitted a proposal last week to the state government. Alongside the revision of milk prices, the state government has also hiked the prices of curd by Rs 2 per liter.

The sudden hike in the prices of milk, curd is likely to have a cascading effect on the milk related beverages such as coffee, tea, and milkshakes with hoteliers and eateries mulling to increase the prices of coffee and tea following the hike in prices.

Sources in the state government revealed to DH that out of Rs 2, farmers will be getting a lion’s share as their accounts will be credited with Rs 1. Another 40 paise will be given to the farmers towards the insurances of their livestock.

Another 40 paise will go to the milk salesmen in the form of commission. The remaining 20 paise will be distributed among the workforce at the milk cooperative unions as an additional incentive.
