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, Jul 19: Three legislators of the opposition Congress in Karnataka, including 2 MLAs and 1 MLC tested positive for coronavirus and are under treatment, a party official said on Saturday.

"Our Bailhongal MLA Mahantesh Koujalgi in Belagavi district and Humnabad MLA Rajashekhar Patil and his MLC brother Chandrashekhar Patil in Bidar district tested positive for the infection and are under treatment at designated hospitals," party spokesman Ravi Gowda told media persons in Bangaluru.

Koujalgi's swab sample was taken on Friday after he showed signs of illness and its result turned positive earlier in the day.

"As Koujalgi attended a review meeting at Bailhongal, about 20 officials who participated in the meeting have been home quarantined," said Gowda.

Koujalgi is the second lawmaker in the state's northwest region to test positive after BJP's Belagavi North assembly segment MLA Anik Benake tested positive for the virus on July 15.

"Patil brothers were in self quarantine after meeting BJP's Bidar Lok Sabha member Bhagwanth Khuba, who tested positive on Wednesday. Their tests also showed they were infected with the virus," Gowda said.

Congress MLC Sandesh Nagaraj, who tested positive on Friday, is under treatment at a private hospital in Mysuru.

Dakshina Kannada district Youth Congress president Mithun Rai is in institutional quarantine in Bengaluru after he tested positive for the infection.

Bengaluru, Feb 21: The Supreme Court in its interim order on Thursday allowed the plea of the Karnataka government for implementation of the final award by a tribunal for sharing of water between Goa, Karnataka and Maharashtra from the Mahadayi river.

The interim order was passed by a bench comprising Justice D Y Chandrachud and Justice Hemant Gupta after hearing the counsel from the three states. The bench said the final hearing in the matter will take place in July.

It also said the interim order is subject to the final outcome of the petitions filed by the three states against the tribunal's award.

The Mahadayi Water Dispute tribunal had passed the order on August 14, 2018, allocating 13.42 TMC ( Thousand Million Cubic Feet.) water (including 3.9 TMC for diversion into the depleted Malaprabha river basin) from the Mahadayi river basin to Karnataka.

Maharashtra was allotted 1.33 TMC water while Goa was given 24 TMC in the final decision of the tribunal. The UPA-2 government had constituted Mahadayi Water Disputes Tribunal in 2010.

Karnataka government, which has locked horns with the neighbouring Goa on the larger issue of sharing Mahadayi River water between both the states, had petitioned the tribunal seeking the release of 7.56 tmcft of water for the Kalasa-Banduri Nala project.

The Kalasa-Banduri Nala (diversion) project, which will utilise 7.56 tmcft of water from the inter-state Mahadayi river, is being undertaken by Karnataka to improve drinking water supply to the twin cities of Hubballi-Dharwad and the districts of Belagavi and Gadag.

It involves building barrages across Kalasa and Banduri, the tributaries of the Mahadayi River, to divert 7.56 tmc water to the Malaprabha river which fulfils the drinking water needs of the twin cities.

Bengaluru, Jan 6: A delegation of Christians, led by Peter Machado, archbishop of Bengaluru, met chief minister BS Yediyurappa on Sunday and sought an amicable solution to the issue of installing a statue of Jesus Christ atop Kapalibetta in Harobele village, Kanakapura taluk.

Yediyurappa is learnt to have assured the delegation of doing the needful and said he would take a decision after the revenue department submits its report. The department is looking into various aspects of the issue, including the sanction of 10 acres of land for the purpose.

“The meeting was cordial and the chief minister lent us a patient hearing. Our only request was to settle the issue in a way that is acceptable to all sections of society,” Machado said. Congress functionary and Kanakapura legislator DK Shivakumar had laid the foundation stone for the 114-foot statue of Christ on Kapalibetta on Christmas Day at an event organised by the Harobele Kapalibetta Development Trust, which plans to install the statue.

The issue took a political hue when BJP functionaries objected, saying the land sanctioned to the trust is part of gomala (reserved for cattle grazing) land and any religious activity there would be illegal. Revenue minister R Ashoka sought a report and department officials said they would submit it in a week’s time.
