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.

New Delhi, Mar 29: "What corona? My children are hungry, they have walked from Gurugram with me do you think corona is what I fear?," Yogesh Gangwar who is salesman in a cloth showroom said as he wiped his tears.

Many others regret for not leaving the city early on.

"God knows when we will reach our hometown. My family was telling me to leave work early in March and get back, but I avoided suggestions and now I am stranded here," Babu Ram who hails from Rampur and works at a plastic recycling factory here in Mundka told media.

Migrant labourers were forced to walk as the public transport were closed and borders were sealed due to the lockdown.

"There is no food to eat, I cannot pay rent of room without my daily wages so I decided to walk with my family from Narela to here. I just hope I get a bus soon," Revati, who works as construction labour said as she fed her three-year-old with pieces of bread that one of the policemen at Anand Vihar gave her.

However, when Yogi Adityanath-led BJP government in Uttar Pradesh decided to deploy around 1,000 buses to help these workers reach their respective hometowns, thousands of them reached Anand Vihar ISBT with a hope to catch one of these buses.

The Delhi government also announced that 100 buses have been deployed to help those trying to reach to their homes in other states on foot.

In order to avoid the spread of the virus, the police asked the people to stand in three queues and also asked the people to de-board the overcrowded buses.

Earlier, budget passenger carrier SpiceJet had offered its aircraft to operate few flights from Delhi and Mumbai to Patna to take migrant labourers, particularly from Bihar, who have got stuck in various parts of the country due to COVID-19 related lockdown.

A motley group of as many as 150 birders ‘walked the chirp’ in search of their feathered friends in and around the countryside of Manipal. The occasion was the 10th Edition of Manipal Bird Day organised by Manipal Birders Group on Sunday, February 2nd, 2020.

The day began ‘Bird Walk’ from Hotel Sheela Sagar (Opposite MIT campus) at 6:30 a.m. The birders divided themselves in smaller groups of 10-12 members and followed 13 different trails which took them through different terrains like hills, plains, paddy fields and wetlands. The idea was to sight as many birds as possible and record their presence in the region.

When the walk ended at about 10:00 a.m., the different groups have recorded a total of 125 species of birds, which was a bit lesser than the sighting of the yester years. “The 10th edition this year has seen a very good growth of interest among people. At the same time a decline has been seen in the bird species sighted compared to previous years,” said one of the organisers. Some of the rare birds sighted were Indian Pitta, Oriental Turtle Dove, Fork-Tailed Drongo Cuckoo, Orange Breasted Green Pigeon, Eurasian Marsh Harrier and Malabar Pied Hornbill.

The bird walk was followed with an interaction session at KMC Food Court and MAHE Vice Chancellor Dr. H. Vinod Bhat presided over the function. He felicitated six people who actively participated recently in a rescue mission of abandoned birds in Manipal.

A program then continued with a talk on ‘Ethical Photography’ by Dhruvam Desai, final year student of MIT, Manipal. This was followed by ‘Backyard Birding’ with Shubha Bhat from IISc Bangalore. She spoke on different ways to feed the birds with water using different materials for bird baths. “I have recorded 120 species of birds from bird baths in my garden,” she said. She encouraged the participants to have bird baths in their gardens or flats which will help quench the thirst of these little winged wonders during summer.

The participants involved themselves actively in the interaction sessions. The event was accompanied with an art exhibition titled ‘Feathered Jewels’ by Aditya Bhat. He presented around 18 paintings all from his memory of birding encounters.

Participation in Manipal Bird Day was open to all and entry was free.

MANIPAL BIRD DAY

Manipal Bird Day is an annual event dedicated to celebrating birds in Manipal. This day long event brings together a large number of birders from Manipal, Udupi, Mangalore, Mysore, Bangalore, Davangere and other places. Around 150-200 people gather and are split into different teams. They visit the assigned regions and count as many birds as possible. This non competitive event focuses on spreading awareness regarding the diverse avifauna around us. Turn out for this event has been increasing from 3 people to 200 in last 10 years. This is the 10th edition of Manipal Bird Day.

MANIPAL BIRDERS CLUB

Manipal Birders Club started as a Facebook group after the release of the first edition of “A Birders Handbook to Manipal” to share information about the latest sightings. It is now a formal group of over 500 like-minded members that meets at least once a week to go on bird walks. It is now a large birders community and a medium to organize events, bird walks and discussions about birds and sightings.

The next step would be to involve a higher number of local and young birders who will dictate the change in environment around the town in the coming years. With the co operation of Zoology and natural sciences students and other nature enthusiasts and faculty of different colleges weekly birding sessions have been conducted to involve and encourage more and more people to bird and get connected to the nature and to try to understand the changes happening around us, the media release issued by the group said.
