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.

Bengaluru, Mar 8: Lieutenant General Milind Hemant Thakur, Director-General of Supply and Transport Corps of the Indian Army, unveiled the renovated Animal Memorial at Agram Grounds in ASC Centre and College here on Saturday.

The animal memorial signifies the contributions of mules and horses of the Indian Army. These animals belonging to the Army Service Corps, who have rendered their services relentlessly during the war in the Himalayas, often paying the highest price of sacrificing their lives in the line of duty have been chronicled in the Memorial.

To ensure that these hoof prints do not get obliterated, on approval by the Government of India, their saga was brought to life in the form of a sculptured monument in the Equestrian Training Area of the ASC Centre and College.

This animal transport memorial has now been extended by constructing two walls supported by Roman pillars on either side.

These walls highlight the role played by the animals in the Indian Army since the British Raj. It gives details of 637 gallantry awards won by the brave muleteers, 49 battle casualties since independence, 14 gallantry awards to mules since independence and 05 military recognitions bestowed by the Chief of the Army Staff and other Army Commanders on AT units, who have been relied upon heavily to fill an important niche in the logistics networks of the Indian Army.

Gen Thakur also declared that 26 September each year has been nominated as the AT Remembrance Day as it was on this day in 1914, that 9th mule Corps, as part of the Indian Expeditionary Force, landed at Marseilles in France, to a most hearty and enthusiastic welcome by the French to support the British and allied armies in World War One.
