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, Jul 1: The Meteorological Department has issued a yellow alert and forecasted heavy rains for three coastal districts and 12 more in the south interior Karnataka region, an official said on Tuesday afternoon.

"Thunderstorm with lightning is likely to occur at isolated places over south interior Karnataka from Tuesday to Wednesday," said a Met official.

For Bengaluru city, the Met department has forecast a generally cloudy sky with light rain for the next three days.

Coastal Karnataka -- Dakshina Kannada, Udupi and Uttara Kannada districts have been issued a yellow alert for the next two days with thundershowers and gusty winds.

Winds blowing at speed of 40-50 km per hour are expected on the coast and the Met department warned fishermen against venturing into the sea.

Meanwhile, heavy showers on Sunday night in Vijayapura district gave rise to flash floods in the Doni river and Sogali stream.

An overflowing Doni river submerged the Talikote - Hadaginal bridge, a remnant from the colonial era, and also submerged some agricultural lands. Only recently, these agricultural lands were sown with toor dal plants.

Similarly, many SSLC students also struggled to cross the bridge to reach their examination centres on Monday.

Many houses were also flooded due to the rainfall at Nalatwad and Talikote taluk. Muddebihal, Basavana Bagewadi and Sindagi taluks also witnessed heavy rainfall.

A 40-year-old farmer from Dharwad district was washed away in the Tuppari Halla stream, which is prone to flood during the monsoon season.

Likewise, a truck carrying cotton also got washed away in a stream in Yadgir district.

"There is an offshore trough and a circulation, because of which rain will continue in the coastal area. Only Malnad has not got sufficient rain this year. Probably after two days, Malnad may get some rains," Karnataka State Natural Disaster Monitoring Centre (KSNDMC) Director Srinivas Reddy said. Otherwise, entire state got normal rainfall, said Reddy, though it is not active over Malnad.

Bengaluru, Jan 2: The Congress leadership in Delhi is expected to start the process of selecting a new party chief for Karnataka next week. There are strong indications the race has narrowed to DK Shivakumar and MB Patil.

Party insiders said the leadership almost finalised Shivakumar’s name as the president of Karnataka Pradesh Congress Committee (KPCC), but the decision was put on hold after requests by some senior members.

“It’s not that we are against Shivakumar. We think the party should have a Lingayat at the helm since community strongman and chief minister BS Yediyurappa is at the fag end of his long political career. There’s an opportunity here for a Congressman to occupy that space,” said a senior Congress politician, who didn’t want to be named.

That’s where the candidacy of Patil, a Lingayat, scores high.

The party, however, doesn’t want to compromise on quality and wants an efficient KPCC president who can unite two rival factions within the party, one led by Siddaramaiah and another by former union minister KH Muniyappa.

The need to pick a new state president arose after Dinesh Gundurao resigned from the post last month, taking moral responsibility for Congress’s poor showing in the byelections. Siddaramaiah also stood down as Congress party legislature leader.

The insiders said the new KPCC chief could be announced after January 16. The party might also appoint two working presidents and a new legislature party leader, who will automatically become the opposition’s voice in the assembly.

For the latter position, the name of senior Dalit politician and former deputy chief minister G Parameshwara is doing the rounds. But the party, the sources said, could still ask Siddaramaiah to reconsider his decision and stay on.

Many Congress members had raised questions over his stewardship after the bypoll disappointment. They said on his watch, the party had also fared badly in the assembly and Lok Sabha elections, demanding that he be held accountable.

Siddaramaiah is expected to visit Delhi next week to discuss the leadership issue with party boss Sonia Gandhi. Some other senior Congress members, including BK Hariprasad, are also likely to meet her.
