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.

Mar 11: Two activists of Sangh Parivar have been arrested by the police in Tamil Nadu’s Coimbatore for hurling a petrol bomb at a mosque in Ganapathy on March 5.

The miscreants had hurled petrol bombs at the front gate of Hidayathul Sunnath Jamath Mosque at Vedhambal Nagar near Ganapathy in Coimbatore around 1 am on March 5. Since the bomb did not explode, nobody was injured in the incident.

Following a complaint from the Secretary of the Jama’ath, the police had formed three separate teams to nab the miscreants.

Based on tip-offs, the police detained BJP member Pandi (41) and VHP member Akhil (23), both from Rathnapuri in Coimbatore for inquiry.  The duo has also been remanded to judicial custody.

According to a statement by the Coimbatore police, the accused told the police that they hurled petrol bomb at the mosque to protest against the attack against Anand, a Hindu Munnani functionary a few days ago. The accused also reportedly told the police that they were planning to create more chaos.

Madukkarai Anand, the District Secretary of Hindu Munnani was attacked on March 4, while he was returning home after participating in a pro-CAA dharna organised by the BJP and allied parties in Gandhipuram.

He was allegedly followed by men on two motorbikes, who attacked him with rods. Anand suffered head injuries in the attack and was admitted to a hospital. The Podanur police registered a case for attempt to murder based on a complaint and had also formed special teams to nab the accused. However, no one has been apprehended in that case till now.

Based on the statements given by the accused, the police arrested the two men, seized the two-wheeler they used, two cell phones and the things they used to manufacture the petrol bomb.
