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, Jun 11: The Department of Pharmaceuticals has given its nod for lifting of ban on the export of hydroxychloroquine, Union Minister D V Sadananda Gowda said on Wednesday.

India had banned export of hydroxychloroquine on March 25, with some exceptions, amid views in some quarters that the drug could be used to fight COVID-19. On April 4, it completely banned the exports without any exception.

"Department of Pharmaceuticals has approved the lifting of ban on export of Hydroxychloroquine API as well as formulations. Manufacturers except SEZ/EOU Units have to supply 20 per cent production in the domestic market," the minister of chemicals and fertilisers said in a tweet.

The Directorate General of Foreign Trade (DGFT) has been asked to issue formal notification in this regard, he added.

In another tweet, Gowda said he held discussions with representatives of pharma companies along with some of his ministerial colleagues on the challenges being faced by the industry and on the roadmap to boost exports.

"Had detailed discussion with representatives of pharma companies & association, stakeholder Ministries along with Hon Ministers @piyushGoyal  ji, @HardeepSPuri  ji, & @MansukhMandviya  ji on entire gamut of challenges faced by the industry as well as strategies to boost pharma export," Gowda tweeted.

India exported hydroxychloroquine API (active pharmaceutical ingredient) worth USD 1.22 billion in April-January 2019-20.

During the same period, exports of formulations made from hydroxychloroquine was at USD 5.50 billion.

Bengaluru/Mangaluru, Aug 6: Battered by torrential rains, several parts of Karnataka are facing a flood-like situation for the third consecutive year, putting lives and property at risk. 

Several districts of the state's coastal, Malnad and north interior regions are receiving heavy rains and the showers are expected to continue, while there are reports of landslides in hilly areas of Kodagu and Chikkamagaluru districts.

With flood-like situation in several parts of the state, Chief Minister B S Yediyurappa, who is currently undergoing treatment for COVID-19 infection at a private hospital here, has ordered immediate release of Rs 50 crore for emergency relief.

"In wake of heavy rains in several parts of the state, I have instructed the Chief Secretary to review the situation and issued instructions to DCs (Deputy Commissioners) to closely monitor the situation & take necessary measures. Also ordered immediate release of Rs 50 crores for emergency relief purposes," he tweeted last night.

A statement released by the CMO on Thursday said, Yediyurappa has directed the district in-charge Ministers to take precautionary measures in the wake of heavy rainfall across the state.

He instructed the ministers to remain in their constituencies and tour the damaged areas and also directed them to undertake relief distribution and other necessary measures.

"Rs 50 crore has already been released and if necessary more funds would be released. The ministers can take decisions regarding emergency works," he added.

Revenue Minister R Ashoka said he had spoken to Deputy Commissioners of all the districts and given them necessary instructions to respond immediately to the situation.

He has called for a meeting of the disaster management authority later today.

Home Minister Basavaraj Bommai said he will be holding a meeting with the State Disaster Response Force (SDRF) regarding relief and rescue measures to be taken.

Parts of districts in coastal and Malnad regions are currently under red alert and rains are likely to continue there.

Officials said, "... depending on the situation we will downgrade the alerts, it (rains) is likely to reduce during the next couple of days...wind speed is also high some parts, it may also reduce."

In Kodagu district along with widespread rains, landslides have also occurred.

There have been landslides at Brahmagiri, near Talacauvery, the origin of river Cauvery.

"At least four to five people- including the Talacauvery temple priest and family are currently missing... rescue teams have reached the spot," officials said, adding that sensing danger the priest had been asked to vacate the house earlier but he did not.

This is the third consecutive year that Kodagu is facing floods and landslides.

Several parts of north Karnataka, especially the border district of Belagavi are also facing flood situation as inflow has increased in Krishna river and its tributaries due to heavy rains in neighboring Maharashtra and also in the district.

With inflow increasing in Tungabhadra river, there is flood like situation in parts of Ballari district also.

There is a similar situation in Uttara Kannada district that is battered by rains and heavy winds.

The swollen Gangavali river has caused flood like situation in parts of the district.

Due to continuous rains in coastal and Malnad region several rivers including Netravati are swollen and gates of the dams have been opened.

There are also reports of heavy rains and wind causing destruction to crops in parts of Dharwad and Haveri among other districts.

The Karnataka government had recently said it has identified 1,989 villages and over 51 lakh people in 19 districts as flood prone.

As a temporary arrangement for those who will be affected by floods, as many as 1,747 relief centres have been identified- they are schools, anganwadi centres, community centres among others, Minister Ashoka had said recently.

In August 2019, Karnataka witnessed one of its worst natural calamities when heavy floods affected 103 taluks in 22 districts, killing more than 80 people and displacing nearly seven lakh people.
