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, Jul 1: Karnataka Primary and Secondary Education Minister S Suresh Kumar on Wednesday played down reports about confusion regarding valuation of Second Pre- University and the Secondary School Leaving Certificate exam papers.

"Creating confusion has become a habit. There was confusion before the exam, during the exam and now confusion about the valuation of the exam papers," Kumar told reporters in Ramanagara when asked about the confusion over the valuation of answer sheets.

He had gone there to inspect a few centres where the SSLC or the 10th standard exams are underway.

The minister reminded people not to speak about the abilities of the students with contempt.

"Our students have toiled hard and are enthusiastically appearing for the examination. They are eligible for the marks they will score. So we should not speak about our children with disrespect," Kumar said.

The Education Minister said he had spoken to many leaders including former chief ministers Siddaramaiah and H D Kumaraswamy on conducting the examinations.

"Kumaraswamy had insisted on postponing the examination. I personally spoke to him and apprised him about the steps taken by us. I told him that we will work with more sincerity to ensure the safety of the children," Kumar said.

The SSLC exam was scheduled to take place from March 27 but due to the coronavirus-induced lockdown, it was postponed.

While the CBSE and a few other states either decided to give marks based on the students' performance in the previous examinations such as quarterly and half-yearly exams or gave general promotion to the students, Karnataka went ahead to hold the exam.

According to Karnataka Secondary Education Examination Board officials, around 8.5 lakh students have enrolled this year for the SSLC examination.

The exams are being held at 2,879 exam centres across the state.

Prior to the SSLC examination, the last exam of the Second PUC was also conducted on June 18, which was also put on hold due to the lockdown.
