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, Jan 24: After Honnalli legislator MP Renukacharya, Ballari City MLA Somashekara Reddy and deputy chief minister Govind Karjol, it appeared the turn of revenue minister R Ashoka to show the BJP in poor light with controversial and provocative comments against a minority community. This, despite a gag order issued by state BJP president Nalin Kumar Kateel.

Responding to questions on the Mangaluru International Airport bomb scare incident and how the main accused would have been treated had he been a Muslim, Ashoka on Thursday said "all anti-nationals must be shot dead". Meanwhile, Renukacharya, also a political secretary to chief minister BS Yediyurappa, continued his tirade against Muslims, insisting the government will not extend any "special package" to the community.

Soon after garlanding the statue of Netaji Subhas Chandra Bose on the birth anniversary of the freedom fighter, at Vidhana Soudha on Thursday, Ashoka said: "All those who are singing the tune of Pakistan and indulging in anti-national activities, be they Hindu, Christian or Muslim, must be shot dead."

Asked to respond to former chief minister HD Kumaraswamy’s accusation that the entire Mangaluru bomb incident was stage-managed by the BJP government to divert attention, Ashoka said the JD(S) functionary "must measure his words" and not speak "like a film director who can project the police as villainous all the time".

"Kumaraswamy is a former CM. When in power, police were his closest friends, but now that he is not in government, the same police are villains," Ashoka said.

The minister reiterated the government’s stand — first floated by home minister Basavaraj Bommai —

that Aditya Rao, the main accused in the Mangaluru bomb incident, is "mentally unstable" and needs to be medically examined.

Renukacharya, meanwhile, justified comments made on Wednesday that the government will not offer Muslims "a special package".

"When they [Muslims] need development funds, they come to us and seek special packages. Once they get funds, they then vote for Congress or JD(S) in elections," Renukacharya said on Thursday. "We do not need people with such double standards. I will apply pressure on all ministers in the cabinet and even the chief minister to ensure they do not allocate any special package for the community."

Mangaluru, May 24: A youth committed suicide by jumping into River Netravati from the old bridge at Panemangaluru on the outskirts of the city. 

The deceased has been identified as Nishant, son of Chandrahasa Moolya, a resident of Kolakeeru, near Kalladka in Bantwal taluk. 

When Nishant jumped to river, a few Muslim youths - identified as Shameer Goodinabali, Mohammad, Tauseef, Mukhtar, Zahid and Arif - also jumped to river in an apparent bid to rescue him. 

Though they managed to take an unconscious Nishant out of the water, he breathed his last without responding to any treatment. Jurisdictional Bantwal town police visited the spot later.

Meanwhile, a few locals captured the video of Muslim youths' attempt to rescue a Hindu youth on Eid al-Fitr amidst covid-19 lockdown. The video went viral within hours. 

Social media platforms including WhatsApp and Facebook flooded with messages appreciating the courage of Muslim men, who endangered their lives to save a Hindu youth on Eid day.
