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, Feb 18:  A fan of Kannada film star Darshan smashed the face of a police constable with a boulder when the latter asked him to come in the queue to a party to celebrate the star’s birthday.

The incident happened past midnight on February 15 near the residence of the film star where his birthday was being celebrated.

The injured police constable has been identified as Devaraj, attached to the Jnana Bharathi police station.

The film star’s managers had not made arrangements to handle a huge crowd that gathered near his residence and police had a tough time controlling the crowd.

Constable Devaraj was deputed to duty at the party and tried to get the crowd to fall in line.

As the police carried out a mild lathi-charge to control the crowd, a fan of Darshan came up with a boulder in his hand and smashed the face of the constable Devaraj from very close distance. The constable collapsed on the spot and the attacker ran away.

The impact was such that Devaraj’s nose was fractured and he sustained an eye injury. He was admitted to a private hospital and his condition is said to be serious.

The R R Nagar police have registered a case under IPC sections 353 and 352. The cops have launched a hunt for the accused and they are obtaining CCTV footage from the spot.

A complaint is being registered against the organisers of the event and an investigation is on. Several neighbours of Darshan have also complained to the police about the chaos on February 15.

Mangaluru, Apr 23: The scarcity of water in Kukkavu area of Belthangady town in Dakshina Kannada district has forced school-going children to dig a well with their hands.
The children studying in primary schools were seen lifting the heavy buckets of water from the well.

The residents were facing the water shortage from the past couple of days, amid the coronavirus lockdown.
A group of five adolescents managed to dug the well as deep as 12 feet within just a span of four days.

" We are facing water problem now. With the support of my five more friends, we dug this well. At the beginning we just found soil, then in the deeper layers, we also found stones. We got access to the water at 10 feet down," said Dhanush, a class 9th student, while speaking to news agency.

The shortage of water during the summer months is a perennial problem in across several states in India, and the growing population has only added to the woes.

In extreme conditions, poor have to draw water from small water holes.
