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.

Bengaluru, Jun 23: Karnataka Congress leader and Kanakapura MLA DK Shivakumar said on Monday that in the wake of coronavirus pandemic, people of his assembly constituency have taken a unanimous decision of remaining under voluntary lockdown until July 1.

The decision was taken after he headed a meeting at Kanakapura on Sunday, at the office of Kanakapura Municipality.

"Let us consider the situation after July 1, hold a similar meeting, and take the next decision. It has nothing to do with the state government's mandate. It came to the conclusion that this was a decision that we all voluntarily took," said DK Shivakumar.

DK Shivakumar informed that the merchants have agreed to sell groceries, fruits, vegetables, fennel, meat and other food items from 7 a.m. to 11 p.m. only. District authorities, DCs, SPs and hospital representatives have decided the timings of clinics and drug stores.

He further said, "In this self-motivated lockdown, unnecessary driving should be avoided. The social gap must be maintained. No one should be oppressed by anyone."

Member of Parliament DK Suresh, Ravi - Ramanagara District Collector Archana, SP Anoop Shetty, and Kanakapura Planning Authority Chairman Jagannath were also present in the meeting.

Thiruvananthapuram, Jan 1: Kerala chief minister Pinarayi Vijayan on Wednesday said that the resolution passed by the Kerala Assembly is against the "unconstitutional Act passed by the Centre".

"The resolution passed by Kerala Assembly is against the unconstitutional Act passed by the Centre. It has been noticed by the whole country," Vijayan said.

The Kerala Assembly had on Tuesday passed a resolution seeking withdrawal of the Citizenship (Amendment) Act, 2019.

Before the resolution was passed against the Act, Vijayan in a special Assembly session targeted RSS and said that citizenship law is part of an agenda.

"The CAA is part of an agenda. Muslims are being considered as internal enemies by RSS, who is controlling the ruling dispensation at the Centre," he alleged.

The new law grants citizenship to Hindus, Sikhs, Jains, Parsis, Buddhists and Christians fleeing religious persecution in Pakistan, Afghanistan and Bangladesh who came to India on or before December 31, 2014.

Meanwhile, on Wednesday while talking about women safety, the Chief Minister said, "Those women, who are traveling face many problems, particularly regarding accommodation. To address this, government will start accommodation facilities in all towns. This project will be implemented with the help of local bodies."

Reacting to the development in the Kerala Assembly, BJP leader Mukhtar Abbas Naqvi said that Assembly has insulted the Constitution and parliament by passing a resolution seeking withdrawal of the Citizenship Amendment Act (CAA).

"The Constitution has delineated clearly the roles of parliament and state legislatures. When people who have taken an oath of the constitution, destroy it, it is a most irresponsible act. Both the houses of parliament have passed CAA and if a state assembly tries to hijack the Act it is an insult not only of the constitution but the parliament as well," Naqvi told news agency.

Dear scape goat Naqvi, dont try to fool us.   I know you are a liar as you are int he company of liars.  MPs are taking oath to respect and safeguard indian constitution and not to disrespect it and go agaisnt the teachings of constitution.  What Central Govt has done is 100 perent agaisnt the constitution and every citizen has the right to oppose this.   You are definately go with the Govt as you are paid for it.   But dont force other too to follow you.  What Kerala Govt has done is according to will of people and Central Govtr should respect it.
