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?

New Delhi, Feb 28: They could hear shots being fired, sense smell of property and vehicles being burnt and feel the stones being pelted. Despite the mayhem that unfolded just a few steps away from their doorsteps, many Muslim households did not feel unsafe due to their Hindu neighbours during the violence in Delhi earlier this week.

Tarannum, a resident of Chand Bagh, said she cannot thank her neighbour Nem Singh enough for saving 15 members of her family that fateful night of February 25. Singh, an auto-rickshaw driver, lives right across her house.

"I could hear the thumping on the door. Our neighbour came to rescue us and assured us that no harm would come to our family, " said Tarannum who lives in lane number 7.

"We thought khayamat has come. Our kids too got scared. Those indulging in rioting are just terrorists. Hindu brothers gave us shelter and saved us. How should I say that they are Hindus or Muslims? When we were under attack, these Hindu brothers provided us safety. We should not fight, " said Tarannum while recounting the horror.

She said a mob has no face, no religion. "I want to tell everyone mob has no name, no religion. Kaun sa pathar kisne mara kisko laga pata hai kya? Pathar ne mazhab dekha kya? (Which stone was thrown by whom, who was hit, does anyone know. Stone does not have a religion," she said.

Singh said he could not bear the wailings of his neighbour's kids.

"Dar to tha par apni gali mein kisi ko pareshan nahi hone dena tha. (I too was afraid but I could not have let them hurt my neighbours)," said Singh when asked if he could have also been attacked for giving shelter to Tarannum family.

"I told them that the rioters will have to go through us first. We all were equally scared," recalled Singh.

Jameel, another local resident, said that his Hindu neighbours were even ready to sacrifice their lives to save him from the ruthless terrorists hired by pro-CAA politicians to unleash violence against Muslims.

Shivamogga, Feb 4: Students of a government primary school which is built especially for the children of manual scavengers, have been facing tough times during classes as the filthy drainage passing through the school premises excrete human excreta and sludge.

The drainage passes through GSPL Scavenger's Colony School in Shivamogga city, located behind the state road transport corporation's bus stand (KSRTC).

According to the locals here, students studying in this school often fall sick due to the waste flowing from the drainage.

Penchelayya, the father of a child who studies in the same school said, "Human excreta floats in the drainage as it is connected to two toilets. The school stinks and students often fall sick due to the drainage."

The students studying here are unable to bear the foul smell emanating from the drainage which flows at the school's premises.

He added that waste from private bus stands is dumped in this drainage which ultimately flows here creating an extremely unhygienic environment for the people living here and students studying in this school.

He further claimed that the government is not ready to listen to their grievances.

Bengaluru, Aug 9: Swollen rivers and flood-like situation continue to threaten lives and property in several parts of Karnataka that have been ravaged by torrential rains over the last few days.

Though there has been a respite from the downpour in some parts, rivers continue to flow above the danger mark, inundating low lying areas in several parts of Malnad, coastal and interior Karnataka.

There are also reports of continued landslides in hilly areas of Kodagu and Chikkamagaluru.

In Dakshina Kannada, heavy rains have submerged several areas in Bantwala and Belthangady, among others, with the Netravati river overflowing and also water being released from nearby dams.

Officials said incessant rains in Cauvery river catchment areas have led to increased inflow in the Krishna Raja Sagara dam in Mandya district. Water is being released from it and people living in low lying areas have been warned, they said.

There is also a flood-like situation in Najanagudu and nearby areas of Mysuru as the swollen Kapila river has inundated roads connecting Ooty in neighbouring Tamil Nadu, with water being released from Kabini dam.

There has been some respite from heavy rains in certain parts of Kodagu, which has been ravaged by floods and landslides. However, several areas of the district continue to be in deluge with the Cauvery and Lakshmana Tirtha rivers overflowing due to rains in the hilly areas.

There are also reports of landslides in some parts of the district.

Meanwhile, continuing rains are hampering the search operation by NDRF and authorities to locate five people, including the priest at Talacauvery, the origin of the river Cauvery, who had gone missing due to massive landslides at Bramhagiri hills on Wednesday night.

There are also reports of landslides at a few places in Charmadi ghat region of Chikkamagaluru and the road connecting to Dakshina Kannada has been closed temporarily.

Though Belagavi district has had some respite from the heavy rains, flood like situation continues to persist as the Krishna river and its tributaries are swollen due to continued inflows because of rains in neighbouring Maharashtra.

Inflow has also increased to the Tungabhadra dam of Ballari district due to rains in the catchment areas of Shivamogga and Chikkamagaluru.

Authorities have alerted people living in low lying areas about opening dam gates to release water anytime with rising inflow.

There is a similar flood like situation in parts of Yadgir, Raichur and Bagalkote districts with water being released from various dams.

The state government has released ₹ 50 crore for emergency relief and has announced ₹ 10,000 as immediate relief each to affected families.

An amount of ₹ 5 lakh has been announced for completely damaged houses, while in the case of partially damaged ones, relief will be distributed considering the extent of damage.
