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?

Kochi, Feb 29: The Kerala Non-Resident Indians' Commission on Friday passed a resolution to request the Centre and Election Commission (EC) to make appropriate amendments in the Representation of Peoples Act, 1951, to ensure voting rights to the non-resident Indians working abroad. According to People’s Representation Act, 1951, None-Resident Indians (NRIs) can vote by proxy.

The Commission is a statutory body constituted for the welfare of Non-Resident Keralites working outside India.

The Centre had introduced a bill for this purpose which was passed by the Lok Sabha in 2018, but the same has since lapsed.

Therefore, the Kerala NRI Commission decided to request the Centre to consider introducing the bill in the next session of Parliament considering the interest of the NRI community at large.

The resolution was moved by commission member and NRI entrepreneur Shamsheer Vayalil, who is also a petitioner in the writ petition, filed regarding this in the Supreme Court.

"The central government may consider introducing the bill in the next session of the Parliament session considering the interest of the NRI community at large," read the resolution which will now be sent to the Ministry of Law and the Election Commission (EC).

Commission chairman Justice PD Rajan said the right to vote for NRIs is a genuine demand.

"This is the time that we step up pressure on the agencies concerned to implement this. Voting from the workplace would be a different experience for them. It would be a decisive step," he said.

This fresh development comes at a time when a petition filed in the Supreme Court on the same topic last week came before a bench headed by Justice Deepak Gupta, which considered the case and said it will be heard in April.

"We are expecting a favourable decision from the Supreme Court. We would also approach the NRI commission in other states and request them to raise the same demand," said Vayalil.

If implemented, millions of NRIs around the world would be able to exercise their franchise in the electoral processes of the nation. According to the estimate of the Ministry of External Affairs, there are about 3.10 crore NRIs.

Kerala Health Minister KK Shailaja on Wednesday had informed that three positive cases of Coronavirus were found in the state and other suspects were being monitored in isolation.

The virus originated in Wuhan in December and has since then spread to various parts around the world.

China has imposed quarantine and travel restrictions, affecting the movement of 56 million people in more than a dozen cities, amid fears that the transmission rate will accelerate.
