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, Jun 5: The Karnataka government has asked all its departments and authorities to avoid during all official transactions the nomenclature "Dalit" for members belonging to the Scheduled Castes.

"All the departments and authorities of government of Karnataka are requested that (use of name Dalit) for all official transactions, matters, dealings, certificates, among others," the official circular said.

The Constitutional term Scheduled Caste in English and its appropriate translation in other national languages should alone be used for denoting the persons belonging to the Scheduled Castes/ Scheduled Tribes notified in the presidential orders issued under Article 341 of the Constitution, the circular said.

The circular issued on May 20 notes instructions issued by the Central government in 2018, with reference to the order of the High Court of Madhya Pradesh, Gwalior Bench.

"That the Central government/state government and its functionaries would refrain from using the nomenclature "Dalit" for the members belonging to Scheduled Castes and Scheduled Tribes as the same does not find mentioned in the Constitution or any statute," the order had said.

Pointing out that the Central government had earlier issued instructions that the words "Harijan" and "Girijan" should not be used, the circular said accordingly the Karnataka government also had issued a Government Order in 2010.
