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, June 11: Amulya Leona, a college student, who was charged with sedition for raising "Pakistan zindabad" slogans in Bengaluru, has finally been granted bail. 

The court had denied her bail yesterday, saying she might abscond. But her lawyers had been pursuing another way of getting her out of jail where she has spent nearly four months.

Ms Leona's advocate, Prasanna R, said that the delay of the state in submitting a chargesheet in the case beyond the stipulated time meant she was eligible for "default bail".

"The default bail application was moved before the magistrate under whose jurisdiction the alleged crime was committed. The chargesheet has not been submitted by the state within 90 days. So default bail has been granted. We had moved the default bail plea on May 26 and again on May 29 when the court told us the earlier mail IDs had been disabled. A physical application was filed on June 2. The state filed the chargesheet on June 3," the lawyer said.

While the state tried to argue that they were entitled to an extension in the time allotted, the court hearing this aspect of the case gave an order favourable to Ms Leona. The process is on to release her.

The arrest of Ms Leona during a rally against the Citizenship (Amendment) Act or CAA in Bengaluru had led to a debate on the use of sedition charges.

The woman on a Facebook post had also said "zindabad" to many countries including India and Pakistan. She did also try to chant "Hindustan zindabad", but was soon silenced and whisked away. She was accused of sedition, causing enmity between communities and causing deliberate mischief.
