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?

In the wake of Saudi Arabia's assurance that Masjid al-Haram of Makkah and Masjid an-Nabawi of Madinah will be opened for believers after some days, a message has gone viral on social media claiming that both the holy mosques will open on Ramadan 8 (May 1).

The message which was widely circulated on Facebook and WhatsApp, also contained certain condition such as people should fetch their own prayer mats and that they should not use the washrooms in the mosques. 

Clarification

Meanwhile, the authorities of the two holy mosques, issued a clarification that the claims made in the viral post are false and baseless.

"The message being circulated about the opening date for Haramiain (two holy mosques) for public is completely baseless and false. The suspension of prayers for general public is still in effect," they said in a social media post.

Kalaburagi, Jan 1: Fighting penury and partial blindness in one eye, a 39-year-old part-time Kannada lecturer from Kalaburagi district is set to become a commercial tax officer after cracking the Karnataka Administrative Services.

Ambadas Kamble, from Kotana Hipparaga village in Aland taluk, had to take a three-year gap during his school and college years - one-year break after completing Class VII and two years to clear subjects after he failed in II PU examinations. During those three years, he joined his brothers in masonry work to supplement the family's income.

Sweeping aside all hurdles with grit and determination, Ambadas studied Kannada literature for both undergraduate and postgraduate to land the post of a part-time lecturer in a Kalaburagi college. His father died when he was a child, and mother Chandamma supported her family of six - besides, Ambadas, she has two sons and two daughters - by working in houses in the neighbourhood.

Ambadas said he would like to dedicate his success to his mother, who died in the year 2012. "My mother encouraged me to chase my dream - financial difficulties notwithstanding - and allowed me to spend time in the library when my siblings were busy doing menial jobs to fund my education. I'm grateful to my brothers too," he said.

His two brothers are working as masons in Mumbai, having quit studies midway and deciding to support Ambadas - the first in the family to complete graduation. He did high school at Tadkal village in Aland taluk, and college in Kalaburagi.

The lecturer, who's 40% blind in the right eye, cracked the KAS examinations in his third attempt and stood 706th in the state. He has been selected for first-grade officer's post. Alongside, he's doing PhD in Kannada literature.

When his efforts finally paid off, Ambadas landed four job offers: Hostel warden at Morarji Desai hostel, at an SC/ST hostel, post of a lecturer and the tax officer's post. He picked the fourth to serve the state in right earnest.
