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.

Bengaluru, Jan 23: An alleged low-intensity blast on Wednesday late evening in Shanthinagar left three-time Congress MLA NA Harris and six others with burn injuries. The blast reported at around 8:30 pm during a cultural programme gripped the central parts of Bengaluru in a panic especially after the incident of police recovering a live bomb in Mangaluru airport. 

According to sources in Shanthinagar, MLA Harris was attending the birthday celebrations of MGR organized by the locals close to his residence in Shanthinagar. Following the blast, Harris and a few others who standing close to the MLA sustained burn injuries and rushed to the nearby Philomena Hospital immediately and police officials from both the Ashok Nagar and Vivek Nagar visited the spot. The police officials are yet to confirm whether it was a bomb blast or due to the bursting of loud and powerful crackers. 

Chethan Singh Rathore, DCP (Central) visited the hospital and the blast site. A team of forensic science lab experts have also been summoned to the spot to collect samples for ascertaining the nature of the blast. MLA Harris’s son Mohammed Nalapad who rushed to the hospital along with supporters told media persons that they are completely shocked by the incident. 

“He was sitting on a chair and suddenly something that was hurled at him exploded beneath the chair. He sustained injuries to his leg and brought to the hospital. He is being treated by a team of doctors and other injured supporters are also being attended to by the doctors,” Nalapad said. 

Expressing shock over the incident, he said, “My father has been an MLA for 12-years and nothing of this sort had happened before in the constituency. We have no rivals and my father never had any gunmen. We are all shocked and have complained to the jurisdictional police.” 

Meantime, Dr Shankar Prasad, Medical Director, St Philomena’s Hospital explained that Harris and others are currently being treated for minor injuries. “None of them have any open cut injuries and they are being examined further,” Dr Prasad told DH. 

According to Dr Prasad, Harris had a minor blood clot in his left leg which was possibly due to a hard object hitting him during the blast. “We have taken X-Ray and examining further. At the look of it, it seems like a very minor injury,” he added.

Mangaluru, May 27: Mangaluru MLA U T Khader today urged Dakshina Kannada MP and Karnataka BJP chief Nalin Kumar Kateel to pave the way for immediate repatriation of Mangalureans stranded across Gulf countries.

The development comes amidst reports that lack of preparedness on part of the authorities concerned in Dakshina Kannada compelled the Centre to delay the operation of repatriation flights from various Gulf to Mangaluru International Airport under Vande Bharat Mission.

Lakhs of people from Mangaluru region (coastal Karnataka) alone are working in middle eastern countries like Saudi Arabia, United Arab Emirates, Kuwait, Bahrain and Qatar. Thousands of them are currently stranded thanks to covid-19 lockdown and are helplessly waiting for repatriation.

Speaking to coastaldigest.com, Mr Khader said he already spoke to Mr Kateel and brought to his notice the plight of Mangalureans in Saudi Arabia and other gulf countries. "There are a large number of pregnant women, senior citizens and patients who need immediate repatriation. It is the responsibility of the elected representatives and district administration to pave the way for the repatriation of our people and arrange quarantine facilities for them," he said. 

"Mr Kaeel is not only MP of Dakshina Kannada. He is also the chief of Karnataka's ruling party. Hence, he must play a crucial role in facilitating the return of Kannadigas in general and Mangalureans in particular," Mr Khader said.
