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, May 24:The first 'Sunday curfew' imposed by the Karnataka government to try and contain the spread of COVID-19 got underway in the state today, with people by and large adhering to norms, roads wearing a deserted look and almost no vehicular traffic, barring essential services.

With barricades being up across most roads in the state, people ventured out only to purchase groceries, vegetabes and medicines.

Instances of violation of Sunday curfew lockdown norms were reported in COVID-19 hotspots of Shivajinagar and Rayapura in Bengaluru and Nelamangala and Devanahalli.

Temples, malls, bars, eateries and small food joints remained shut throughout state.

In most parts of the state buses, autorickshaws and cabs did not ply.

In Bengaluru, the ever bustling Majestic area, which houses the central city bus stand, inter-city bus stand, Metro Railway Station and the City Railway Station, did not see any activity as buses did not ply and all shops were shut, police said.

Reports from Mysuru, Tumakuru, Kolar, Mangaluru, Udupi and other towns across the state said there were no lockdown violations.

Amid the rigid curfew marriages were conducted in a simple manner in various parts of the state like Gollarahatti and Yashwanthapura in Bengaluru and also in Davangere.

Families of the brides and grooms invited only a few people for the event, adhered to social distancing norms and wore masks.

In Gollarahatti, the event organisers cleaned the road, after which the invitees, who were hardly 25 to 30 in number, sat down to have a feast.

The Karnataka government had eased restrictions during Lockdown 4 for start of economic activities like city buses, inter-district bus service, intrastate train services, opening of shops and markets.

However, the government had made it clear that there will be 'Janata Curfew' every Sunday during which only essential services would be permitted.
