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?

Hubballi, Mar 25: The people living in rural areas of North-Karnataka region have become more aware about deadly Corona virus as they are leaving no stone unturned to prevent people of Bengaluru and other metropolitan cities from entering into their villages. People have put thorny plants on all roads at the outskirts connecting their villages and deployed youths to conduct patrolling round the clock till next 21 days.

Their motto is to prevent their own villagers getting infected from the outsiders especially from cities like Bengaluru and other two-tier cities where positive virus cases are on the rise.

"We don't have access to the proper medical care if Corona virus is entered into our village. The Primary Health Centres are not functioning properly and these centers are facing lack of adequate staff and medical equipments unlike in big cities.Therefore, those who have deserted our village to employ in various jobs in Bengaluru and other cities should confirm that they are tested negative for the virus", said Mallikarjun Patil of Kudal village in Hangal taluk of Haveri district. The village has totally banned the outsiders into their village and warned their fellow villagers to return immediately if they have visited to their relatives' homes in neighboring villages to observe 21-day lockdown.

Hundreds of youths in Itanal village of Chikkodi taluk of Belagavi have also resorted to similar tactics and patrolling in all roads at the outskirts by holding sticks to prevent outsiders from entering into their village until April 14.

People of Hunagunti village in Ron taluk and Kotamuchagi village in Gadag taluk have also adopted similar plan by parking tractors at th outskirts to prohibit the entry of outsiders. They have also created awareness in their villages by beating drums urging the people not to venture outside village for next three weeks.
