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, Mar 21: The news and public relations department, the Indian Red Cross Society and the Karnataka State Labour Studies Institute have invited volunteers for the programme to provide real-time information to people to avoid spreading rumours and misinformation about coronavirus.

This is an opportunity to join hands with the Karnataka government and fight coronavirus. These volunteers will be known as the "Corona Warriors", who will be entrusted with the job of monitoring social media sites to check rumours that are being spread across all taluks in the state. They will also take steps to provide proper information.

Applications are already being shared online and registered volunteers will be provided with appropriate training, security kits and identification cards at all district offices of the Department of Information and Public Relations.

At least four volunteers will work in four shifts per day in each taluk of the state. There are about 120 volunteers in Bengaluru city and about 3,000 Corona Warriors are expected to register from across the state. Over 400 volunteers have registered via online application on the first day.

Fifteen people have tested positive for COVID-19 in the state, said Karnataka Health Minister B Sriramulu on Friday.

New Delhi, Feb 13: Two SpiceJet pilots have been suspended today for an improper landing at Mangalore Airport which damaged three runway edge lights. The incident took place on October 31 last year when the private carrier's Boeing 737 aircraft was returning from Dubai.

The Directorate General of Civil Aviation (DGCA) suspended the licenses of the pilots for four-and-half months from the date of the incident.

DGCA had issued a show cause notice to the Pilot in Command and the First Officer demanding explanation of the "lapses" and found their replies unsatisfactory, the aviation watchdog said in a statement.

Investigation revealed that the touchdown was improper as it deviated to the the left on the runway in turn damaging three runway edge lights.
