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.

Mangaluru, June 12: Juma prayers were held in dozens of mosques across coastal district of Dakshina Kannada including the city of Mangaluru for the first time in nearly three months upholding all the safety norms including physical distancing. 

For the first time in the recent history of Mangaluru, juma prayers were stalled in all the mosques for 11 consecutive weeks as part of nationwide coronavirus lockdown. 

While many mosques were reopened for the congregational prayers in the region on June 8 (Monday) after receiving approval from the government, many others are yet to be opened as Muslim religious leaders are taking additional precautionary measures to prevent the spread of covid-19 apart from following all the guidelines issued by the government.

“Around 400 people participated in the Juma prayer at Zeenat Bakhsh Juma Masjid. All the safety guidelines were followed. Sadaqatul Nadwi delivered the sermon and led the prayers,” S M Rasheed Haji, executive member of the mosque committee told coastaldigest.com.

“As per the guidelines, devotees performed Wudu (ablution) at their homes and also carried their own musalla (prayer mat) to the mosque,” said a Jalaluddin, a cleric who offered Juma prayers in Ullal.  

The guidelines issued by the government to the mosques also include disinfecting the premises at regular intervals, maintaining physical distance, wearing masks and finishing prayers in “minimum permissible time”.
