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?

Mangaluru, Aug 8: As visuals of the Air India Express flight crash at Kozhikode international airport emerge, one cannot help but be reminded of an eerily similar and unfortunate accident that occurred a decade ago. The August 7, 2020 tragedy brought back memories of the 2010 crash.

It was on May 22, 2010 that an Air India Express Boeing 737-800 flight from Dubai to Mangaluru over shot the runway while landing at Bajpe airport and fell into a cliff. Of the 160 passengers and 6 crew members on board, 158 were killed (all crew members and 152 passengers) and only 8 survived.

Even back then, the plane had split into two. The crash has been termed as one of India's worst aviation disasters.

The final conversations between Air traffic control (ATC) and the pilot prior to the landing showed no indication of any distress.

Like the Mangaluru accident, Karipur crash too happened when the flight was attempting to land.

The captain of the aircraft which crashed at Mangaluru, Z Glucia, was an experienced pilot with 10,000 hours of flying experience and had 19 landings at the Mangalore airport. Co-pilot S S Ahluwalia, with 3,000 hours of flying experience had as many as 66 landings at this airport. Both the pilot and co-pilot were among the victims.

An investigation into the accident later found that the cause of the accident was the captain’s failure to discontinue an ‘unstabilised approach’ and his persistence to continue with the landing, despite three calls from the First Officer to ‘go-around’.

Tumakuru, Jan 2: Prime Minister Narendra Modi on Thursday paid respects to the 'Gadduge' (final resting place) of Shivakumara Swamiji at Siddaganga Math, a prominent Lingayat seminary here, and said the Swamiji's work would continue to inspire everyone.

The Swamiji, who was known as the 'Walking God' among his countless followers, had passed away last year at the age of 111. The Prime Minister, who arrived at the Yelahanka Airbase in Bengaluru, went directly to Tumakuru, where the Math is located, by a chopper along with Chief Minister B S Yediyurappa, Union Minister Pralhad Joshi and former Chief Minister D V Sadananda Gowda among others. Modi, after offering respects to the 'Gadduge', planted Bilva plant (Aegle marmelos) on the premises of the Math and also laid the foundation for the construction of a museum dedicated to Swamiji here before addressing the gathering, largely comprising students. Speaking on the occasion, Modi said he was feeling blessed to begin 2020 from the sacred land of Siddaganga, but at the same time was feeling the "vacuum" in the absence of Shivakumara Swamiji. "It is rare see the number of people swamiji had inspired during his life time. I'm really fortunate to lay the foundation for the museum in swamiji's memory. Through this museum, his works will continue to inspire generations," he said. Also, Prime Minister remembered Vishwesha Theertha of Udupi's Pejawar Math who passed away recently. Yediyurappa and the present pontiff of the Math Siddalinga Swamiji were among the others present. Known as "trivida dasohi" for his triple sacraments - food, shelter and education - among his followers, Shivakumara swamiji was considered as the incarnation of Basavanna, the 12th-century social reformer, as he accepted all irrespective of their religion or caste. There has been a growing clamour from people of different walks of life, including politicians, for conferring "Bharat Ratna" on the late Swamiji.

After the Swamiji's demise, the then Chief Minister H D Kumaraswamy had written to Modi urging him to confer the country's highest civilian order on the late seer.

Opposition Congress on Thursday questioned the Prime Minister about not conferring the"Bharat Ratna" on Shivakumara Swamiji.

Questioning Modi as to why he did not visit Tumakuru when Shivakumara Swamiji of Siddaganga Math passed away, the principal opposition party in the state assembly in a tweet also sought to know why the seer was not conferred with the Bharat Ratna yet, while pointing out that former Chief Minister Siddaramaiah had written a letter in this regard in January 2018.

The present seer of the seminary Siddalinga Swamiji presented Modi a silver statue of Shivakumara Swamiji as a memento.
