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, Mar 11: Did Congress party’s Man Friday, DK Shivakumar, not rise up to the occasion and save the situation for the party, whose rebel MLAs were flown into Bengaluru to unsettle the Kamal Nath-led government in Madhya Pradesh? Shivakumar told The New Indian Express on Tuesday, “So far, I have not got any clear direction on what has to be done. But I am in touch with the central leaders. The party does not want to antagonise them... They are our own MLAs.”

He said that the Tenth Schedule, which makes defections illegal, is very strong. “It is not so easy for them once they are expelled. There are courts and then they have to get re-elected. It is not easy to get minister’s post after getting re-elected,” he added.

When pointed out that rebels from the Congress and JD(S) who joined the BJP have got re-elected and become ministers, he said, “There are other issues here.”

Asked about Digvijay Singh, who is at the centre of the controversy in MP and who was AICC general secretary in-charge of Karnataka, not being able to prevent the rebellion in his home state, Shivakumar said, “I do not want to comment on any of our national leaders.”But he was confident that the Congress government would be saved in MP. “I am aware of the developments and keeping track of them,” he said.

Congress leaders seemed wiser after the event.

One of them, who wished not to be identified, said the party clearly did not see the writing on the wall. “Jyotiraditya Scindia supported the BJP at the Centre when it scrapped Article 370. Later too he was not in line with the Congress position on several issues. But during the recent Delhi violence, he criticised the BJP, sending confusing signals,” he added.

Mangalore University has been participating in the campus bird count a sub-event of ‘Great backyard bird count’ (GBBC) organized by Bird Count India for the past 5 years. This year, CBC was held from 14th to 17th February of 2020 across various campuses in India.

This year the four days event was successfully ended up with the sightings of 103 species of birds from various locations across the campus spread on 300 acres. In this Black Drongo, Black Kite, Brahminy Kite, Common Iora, Green Wabler, Purple-rumed Sunbird, Red-whiskered Bulbul, White-cheeked Barbet, Jungle Babbler and Plum headed parakeets were the common birds, and also observed House Crow with nest and nestlings, Indian Robin nest with eggs, Bronzed Drongo constructing the nest and Shikra mating and carrying nesting materials.  Whereas Yellow-billed Babbler is rare in the campus, Ashy Drongo, Barn Swallow, Booted Eagle, Grey Wagtail, Indian Pitta etc. were migratory birds, Grey-headed Bulbul (Near Threatened bird), Rufous Babbler and Grey-headed Bulbul were Western Ghats Endemics  and Brown Wood Owl, Barn Owl, Spotted Owlet, Nightjars (Savanna, Indian and Jerdon’s) and Sri Lanka Frogmouth were nocturnal birds. Blue-eared Kingfisher Grey-bellied Cuckoo which was very rare and new additions to avian list of the campus.

In the first year (2016) of Mangalore University’s CBC recorded 77 species, in 2017 recorded 95 species, in 2018 recorded 110 species and in 2019 recorded 107 species of birds. However some of the common species like Rose ringed parakeets, Blue tailed bee-eater, Nilgiri Flowerpecker and Indian roller etc., sighted last year were not seen this year. But with 2 new additions from this CBC, the checklist of Mangalore University Campus has been updated with a total of 141 species.

This event was coordinated by Vivek Hasyagar from the Department of Applied Zoology and Maxim Rodrigues from the Department of Marine Geology. Survey trails were led by more than 60 students and research scholars from various Departments of Mangalore University includes Applied Zoology, Biosciences, Microbiology, Botany, Physics, Chemistry and Material Science.  In addition, some enthusiastic participants from St. Aloysius College had involved in identifying the birds around the campus.

Quote:

Wild/planned fire affects negatively on the existing ecologically sensitive areas in and around the campus especially in lateritic grasslands. Because many insectivorous birds are dependent on these lateritic grassland habitats for their food and breeding grounds for many ground dwelling birds like Yellow wattled lapwing, Red wattled lapwing, Indian Robin and Barred buttonquails. Conserving these habitats will be helpful in protecting these birds.

Quotes from the participants: “The Campus Bird Count 2020 at Mangalore University was an experience of its own kind. Observing birds in their natural habitat gave me new perspective of viewing them not only as another living being, but as equals, or even of higher intelligence. The Campus Bird Count is an important step towards documenting bird life year after year, and creating awareness amongst youngsters, so that proper conservation steps can be taken to protect them from human interference”.
