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.

Bengaluru, Jan 24: Karnataka Chief Minister BS Yediyurappa on Friday said the much-delayed Cabinet expansion will take place in the next three days.

At the Kempegowda International Airport, after his arrival from Davos, he informed that he would discuss the matter with Union Home Minister Amit Shah to take a final decision on the distribution of important portfolios.

Deputy CM Ashwanath Narayna, Home Minister Basavaraj Bommai and others received the Chief Minister at the airport. The issue of Cabinet expansion was kept in abeyance, ever since the spectacular victory of 12 Assembly seats for BJP, for which the by-elections were held recently. The bypolls were necessitated, following the resignation of about 17 sitting Congress and JD (S) MLAs, which resulted in the collapse of the JDS-Congress coalition government in the state.

BJP had reportedly lured the Congress and JD (S) MLAs into their camp, after promising them to give party ticket to contest the elections, as well as ministerial berths. The Chief Minister had kept as many as 16 Cabinet berths, along with plum portfolios, vacant, after forming the BJP government, with the support of the deserted Congress and JD (S) MLAs, in July last. However, the issue of Cabinet expansion had postponed on one reason or the other, as Yediyurappa was struggling to keep the promise he had made to the former Congress and the JDS MLAs, on whose sacrifice the BJP came back to power.

With the strong demand for ministerial berths within the loyal BJP MLAs, the BJP high command had reportedly advised Yediyurappa to accommodate only a few of the turncoat MLAs and strike balance between the groups.

However, Yediyurappa, who had assured the Congress and JD (S) MLAs of giving them Cabinet berths, had been in dilemma ever since and found it tough to convince the party's Central leaders.

According to party sources, the Chief Minister is not only facing problems over the expansion of his Cabinet, but is also worried over the demand for creation of more number of Deputy Chief Ministers, adding to the present list of three.

Shivamogga, Aug 9: Minister of State for Railways Suresh Angadi on Saturday virtually inaugurated Malgudi Museum at Arasalu in Karantaka's Shivamogga.

The old station building at Arasalu has been converted into museum.
BJP MP from Shivamogga BY Raghavendra said that the old station building at Arasalu has been renovated keeping with 'Malgudi' theme in mind.

"It is a tribute to the makers of the popular television serial 'Malgudi Days' as the station features predominantly in the episodes which broadcast on Doordarshan in the 1980s," he said.

The museum has been designed by a famous artist John Devraj, who was the part of the serial Malgudi Days. The Mysore Divisional Railway funded the museum.

"The approach road and station area wear a new transformed look. The innovative idea of having a tea-shop in a narrow gauge coach at Arasalu station adds charm to the green surroundings," the MP said.

"Popular and internationally acclaimed serial Malgudi Days was shot here in Arasalu. The SWR Mysore division manager Aparna Garg helped to transform the station to fictional village Malgudi," he added.

The museum is about 30 km from Shivamogga city. It has steam engines and bogies besides collections of photographs hanging on the wall taken during the time of shooting for Malgudi Days.
