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.

Bengaluru, Apr 28: Providing respite, Karnataka has decided to ‘conditionally’ allow economic activities to restart in green zones.

The green zones of Chamarajanagar, Koppal, Chikkamagaluru, Raichur, Chitradurga, Ramanagara, Hassan, Shivamogga, Haveri, Yadgir, Kolar, Davangere, Udupi and Kodagu will now see shops and industrial activities starting operations, according to an order issued by Chief Secretary TM Vijay Bhaskar on Tuesday.

Lockdown restrictions in the wake of COVID-19 will continue in Bengaluru Urban, Belagavi, Mysuru, Vijayapura, Bagalkot, Kalaburagi, Bidar and Dakshina Kannada. Here, only essential services and supplies will be allowed.

In green zones, all shops that include neighbourhood shops, standalone shops, shops in residential complexes within the limits of municipal corporations and municipalities can open with 50 per cent manpower but with masks and social distancing mandatory.

Shops in residential and marketing complexes are allowed to open in areas located outside municipal limits, the order states.

Multi-brand and single-brand malls will remain shut across Karnataka.

Industries operating in rural areas of these green zones (except Ramanagara) have been allowed to start. Also, manufacturing and other industrial establishments with access control in special economic zones and export-oriented units, industrial estates and industrial townships will be allowed to operate.

“These establishments shall make arrangements for stay of workers within their premises as far as possible and/ or adjacent buildings. The transportation of workers to workplace shall be arranged by the employers in dedicated transport by ensuring social distancing (sic),” Bhaskar said in the order.

This order comes a day after Chief Minister BS Yediyurappa participated in a video conference with Prime Minister Narendra Modi, and with all deputy commissioners.

No decision on relaxing lockdown restrictions has been taken for Ballari, Mandya, Bengaluru Rural, Gadag, Tumakuru, Chikkaballapur, Uttara Kannada and Dharwad. “The decision regarding opening of shops and industries in taluks where there are no active COVID-19 cases will be taken by the concerned district in-charge minister,” Bhaskar said.

Bengaluru, Aug 3: Karnataka Pradesh Congress Committee working president Satish Jarakiholi on Sunday said that as per the party sources, state chief minister BS Yediyurappa has got only six months' time and there are different teams working against Yediyurappa in their party.

The BJP high command has decided to bring down Yediyurappa, Jarakhioli said. He added, "Yediyurappa had asked BJP high command to appoint him Chief Minister for six months and due to corona, his period has been extended. But now their own party sources have revealed that he has got only another six months."

While addressing the issue of different statements by BJP leaders and ministership aspirants after five MLCs were nominated, Jarakiholi said "Yediyurappa followers are not actual followers. BJP high command has already decided to bring down Yediyurappa as per their own party sources."

While speaking to reporters in Bengaluru, he said there are teams formed in the names of deputy CMs and there are many who are working in their party against Yediyurappa.

He also said that it's up to their party what they think about Yediyurappa's tenure, whether they keep him as CM or remove him. Being in Opposition, now Congress is only working on strengthening the party, he said.

Madikeri, Mar 29: In an alarming situation in neighbouring Kerala State and instances of inter-state migration of Coronavirus suspects, the authorities on Sunday sealed both Dakshina Kannada and Kodagu borders, prohibiting entry of people from Kerala into Karnataka.

Dakshina Kannada had sealed its borders after repeated instances of people misusing ambulance services to travel to Mangalore. Villagers along with the police hauled mud on to the roads that were used as alternate routes.

The road that connects the two States, which people from east Kasargod used to enter into Karnataka, were closed at Mulleria by dumping mud on the road.
