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?

''We have had our (Congress) Task Force meeting today, during which we discussed several matters. There is a lot of difference between the government's talk and its deeds,'' KPCC President D K Shivakumar said.

Bengaluru, Jul 2: Former Karnataka Chief Minister HD Kumaraswamy on Thursday accused BS Yediyurappa-led state government of "failure" to protect the citizens from coronavirus, stating that Karnataka was suffering due to lack of co-ordination in the cabinet.

In a series of tweets, the JD(S) leader slammed the state government for wasting their time in giving out contradictory statements regarding COVID-19 figures instead of learning lessons from the Kerala government.

"It is shocking to see COVID-19 patients being turned down by the hospitals due to lack of beds. The government has failed in its duty to protect the citizens. The CM and his cabinet colleagues wasted precious time in mere talking for the last three months. As the escalated Covid numbers stare them in the face, they are now helpless," Kumaraswamy wrote.

"Even when you have a proven model in Kerala government's success in Covid management, the ministers waste time in issuing contradictory statements and doing nothing. Karnataka suffers due to lack of co-ordination in the cabinet," he said.

Urging the government to act together, he said that if the government does not get its act together, the day is not far when Covid patients would be "condemned to die on the streets."

We are already seeing heart-wrenching stories of patients denied treatment," he added.

Kumaraswamy also appealed to the Karnataka government to consider the suggestions he had made earlier and not to indulge in party politics in these testing times.

"I appeal to the government to consider the suggestions I made earlier and act accordingly. This is not the time for party politics."
