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.

Mangaluru, Jan 15: Thousands of people on Wednesday boarded boats from Ullal's Kotepura to join a massive protest against the amended Citizenship Act and National Register of Citizens (NRC) in Adyar here.

People travelling through boats and steamers decorated with national flags, raised slogans during their journey through the Netravathi River.

The innovative mode of transportation was used by the protestors to reach the venue, as it not only saved time but was also more convenient for the fishermen, as large number of people from this community joined the protest.

The protestors docked their boats at the shore, which was barely 500 metres from the site of protest, being held at Shah Ground in Adyar.

The distance between Kotepura to the Shah Ground is approximately 15 kilometres but protesters would have to walk more five kilometres to reach the venue because of heavy traffic.

Due to protest, the national highway was also blocked and resulted in huge traffic snarls on routes leading to agitation site.

Bengaluru, May 3: Undergraduate and postgraduate students skipping online classes held by their universities run the risk of being debarred from writing their exams. 

State universities, which are monitoring the attendance of online classes, are asking their affiliate colleges to send the monthly online attendance details and this would reflect in their regular attendance. This would apply to those studying professional courses like medicine and engineering. 

State medical education minister Dr K Sudhakar has asked all medical colleges to regularly send attendance details to the Rajiv Gandhi University of Health Sciences (RGUHS).

RGUHS vice-chancellor Dr Sachidanand confirmed to DH that the varsity is indeed monitoring the attendance of students. “Online classes are equal to classroom teaching. (Such method of conducting classes) are necessary during the Covid-19 pandemic and the nationwide lockdown,” he said.

According to the Supreme Court directions, students should have 75% attendance to be eligible to appear for the final exams. There could be relaxations if they have health issues. If students are bunking online classes, it would reflect on their minimum attendance necessary to appear for the exams, the vice-chancellors of state-run varsities said.

Bangalore University vice-chancellor Prof K R Venugopal said most of the students are attending online classes and teachers are messaging the parents of those who are irregular. “(Of course) if they fall short of the minimum attendance, they won’t be allowed to appear for the exams,” he said.

Bengaluru North University vice-chancellor Prof T D Kemparaju said the administration has asked its teachers to record details of students attending online classes and update the university.

Mixed signals 

Meanwhile, the University Grants Commission (UGC) on Wednesday issued guidelines directing all universities to treat the lockdown period as “deemed as attended” for students and research scholars. Experts pointed out that the order would prompt students not to take the online classes seriously.

“Arrangements have been made at the state varsities to make students attend online classes compulsorily and students are also serious about it. Now, because of the UGC guidelines, they may bunk classes,” said the vice-chancellor of a state-run university.
