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, 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.

Newsroom, Jan 29: Karnataka’s capital has earned the unwelcome distinction of global capital of traffic congestion. According to a report by TomTom, the Netherlands-based global provider of navigation, traffic and map products, Bengaluru beat 415 other cities across 57 countries to earn the title of world's most traffic congested city in 2019.

“Bengaluru takes the top spot this year with drivers in the southern Indian city expecting to spend an average of 71% extra travel time stuck in traffic," TomTom said in the ninth edition of its annual Traffic Index.

Three other Indian cities, namely, Mumbai, Pune and New Delhi are also ranked in the 2019 edition of TomTom’s Traffic Index of the world’s most traffic-congested cities. 

The report released on Tuesday ranks cities by the average time added to a trip. TomTom index also includes details on when congestion is heaviest and lightest, how highways compare with surface streets, and how much time drivers wasted waiting for other drivers to get out of their way.

Following closely on the heels of Bengaluru is Manila, Philippines, with the similar 71% traffic congestion. Among the top five worst traffic affected cities are Mumbai and Pune from India at the fourth and fifth place respectively, while Bogota, Colombia is on third spot.

Delhi, the national capital of India is on the 8th spot, while Moscow (Russia), Lima (Peru), Istanbul (Turkey) and Jakarta (Indonesia) are on 6th, 7th, 9th and 10th spot respectively.

Mumbai recorded a 65% traffic congestion with 9th September, 2019 being the worst day. On an average, a Mumbaikar lost 209 hours in traffic congestion. Pune has 59% traffic congestion with 2nd August, 2019 being the worst day. 193 hours are lost due to congestion. Delhi, on the other hand, has 56% traffic congestion. 23rd October, 2019 was the worst day, while 190 hours are lost in traffic congestion.

Interestingly, among all the four Indian cities, Delhi has the most number of cars. Previous studies have concluded that Delhi has the best road conditions among the Metro cities of India.

If you are wondering what exactly the percentages mean, a 53% congestion level in Bangkok, for example, means that a trip will take 53% more time than it would during Bangkok’s baseline uncongested conditions.

TomTom calculates the baseline per city by analyzing free-flow travel times of all vehicles on the entire road network – recorded 24/7, 365 days a year. The report by Dutch navigation and mapping company ranks cities by the average time added to a trip. It also includes details on when congestion is heaviest and lightest, and how much time drivers wasted waiting for other drivers to get out of their way.
