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, Jun 18: Former Karnataka Chief Minister and Congress leader Siddaramaiah has accused the BJP-led government of not passing the benefit of the low price of crude to the common man and urged Prime Minister Narendra Modi to take steps to bring down prices of petroleum products.

Hitting out at the BJP-led government, he termed it as "opportunistic" and said the price of petroleum products were being increased when people were facing difficulties due to COVID-19.

"It is very disheartening to witness and unprecedented opportunistic government which is trying to extract every pound and flesh from the common man, that too when the whole country is suffering from the COVID-19 pandemic. This is in the backdrop of the continuous price hike in the last 10 days," said the letter was written on Wednesday.

The Congress leader said that the policy decisions taken by the government "with respect to managing fuel sources are inconsistent with the prudent measures generally adopted".

"When the price of crude oil was remarkably low in March, April and May 2020, your government was very reluctant to pass on the benefits to the people by reducing the fuel prices proportionately, but, instead, your government continued to capitalise by increasing the excise duty," he said.

He said the government had also "failed" in the last six years to increase the oil storage capacity which could have been used for the country's advantage when the international crude oil price fell really low.

He said the government should roll back the excise duty and help in the reduction of fuel prices.

"The reduced burden will help the common man to have additional money in hand that will be spent on essential goods and services which will ultimately help them tide over these difficult times," he said.

Bengaluru, May 30: A city corporator in Bengaluru was sent into quarantine on Saturday after he tested positive for the coronavirus infection, officials said.

"Yes, I have tested positive," Padarayanapura municipal ward corporator Imran Pasha told some news channels.

The JDS corporator said he would quarantine himself as per the regulations.

The entire area where Pasha lives was cordoned off.

Health workers reached there in an ambulance and gave him a personal protection gear to wear and he was taken to a designated hospital.

Reacting to the development, Karnataka Revenue Minister R Ashoka claimed Pasha hardly paid heed to the COVID-19 regulations.

"He rushes to all those places wherever there are positive cases...," Ashoka told reporters.

Padarayanapura was declared as a containment zone earlier with a few cases coming to the fore.

It was in this area where some policemen and health workers were attacked when they went to quarantine a few primary and secondary contacts of a COVID-19 patient about a month ago.

Following the incident, about 125 people were arrested, and later quarantined after a few of them tested positive.
