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?

Jun 19: BJP leader Devendra Fadnavis on Thursday said Maharashtra Chief Minister Uddhav Thackeray should sign an agreement with neighbouring Karnataka to avoid a repeat of flood in part of the state like it happened in August last year.

In August 2019, Kolhapur, Sangli districts and some other parts of the state faced unprecedented floods triggered by huge release of water from dams in western Maharashtra and from the Almatti dam in Karnataka.

Fadnavis said, The Maharashtra chief minister should hold an urgent meeting with the Karnataka chief minister and enter into an agreement over-discharge of water from the Almatti dam located on the border of both the states."

If water is not released from the Almatti dam in time, it will cause flooding in border areas of Maharashtra such as Kolhapur and Sangli.

"A pact between the two states would benefit both as it would help in keeping water levels in control, the former chief minister said.

The dams in the state already have sizeable water stock. It would be better if the chief minster schedules a meeting with the Karnataka chief minister regarding the same (agreement), the Leader of Opposition in the assembly said.
