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, July 13: The Karnataka government today announced the cancellation of I PUC supplementary examinations across the state. 

Primary and Secondary Education minister S Suresh Kumar announced that the government took the decision in the wake of rising cases of Covid-19 and re-introduction of the lockdown. According to sources in the education department, as many as 60,000 students were supposed to appear for the examination.

Previously, the state government had decided to hold these exams at the college level in every district and publish the results by 30 July. However, the government has withdrawn even that arrangement and completely cancelled the exams. 

According to the minister, all the students who failed in the I PUC examination, shall also be promoted to II PUC. "The students who have attended all the subjects but unable to pass the exams will also be promoted to the next class," Suresh Kumar said.

However, those who missed out on the exams due to health reasons or failed in the examinations will be given a small test at the time of commencing classes for II PUC to assess their learning ability at the college level, according to the minister. "Only those students who missed out on the examination due to shortage of attendance will not be promoted to the next class," Suresh Kumar clarified.
