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?

Kalaburagi, May 16: Former Karnataka Minister Dr Sharanprakash Patil, who was booked for violating COVID-19 imposed lockdown guidelines said on Friday that it was "politically motivated".

"It's politically motivated, the officer who filed the case was forced by MLA or some other people. As elected representatives, we're going in the constituencies, listening to people as they're apprehensive about the return of migrants. We had not conducted any meeting. Wherever we have gone we have followed social distancing," Patil said.

Patil said, "When I had gone there people came to discuss about a local problem and I was talking to an official concerned. In the meantime, some officer gave a complaint that we have violated the lockdown or something."

"They are trying to curb the voice of opposition because there are a lot of lacunae. We hear complaints about quarantine centres that there is no proper facility for food, or stay, or bathrooms," the Congress leader said.

The FIR was registered on Thursday against 23 persons, including the former MLA and 21 local Congress leaders, under Section 188 (disobedience to order duly promulgated by a public servant) of the Indian Penal Code (IPC).

Congress leader Patil and his followers had conducted a meeting at a convention hall in Sulpeth town on May 13, following which sectoral magistrate Muneer Ahmed lodged a complaint.

Mysuru, Jun 18: The Karnataka government's proposal announced on Thursday to hold online classes for students amid concerns over COVID-19 has not gone down well with thousands of tribal students residing in villages across the state.

A team from Karnataka State Commission for Protection of Child Rights (KSCPCR) visited a few tribal hamlets in Mysuru and Kodagu recently and found that the students, unlike their urban counterparts, lack accessibility to not just smartphones and computers, but basic necessities like power supply.

''When such is the situation in the tribal hamlets, how can you expect students to catch up on their studies if classes are held online?'' wondered M L Parashurama Member, KSCPCR, who toured villages like Thithimathi, Beematagere, Devamachchi and Gaddadi in Kodagu's Virajpet taluk, besides Bavali, Balyadi, Machchuru, and Anemone in Mysuru's HD Kote taluk along with Chairperson Antony Sebastian.
