In a study conducted in 117 countries, researchers have found that the world is experiencing the most dramatic reduction in the seismic noise (the hum of vibrations in the planet's crust) in recorded history due to global COVID-19 lockdowns.

Measured by instruments called seismometers, seismic noise is caused by vibrations within the Earth, which travel like waves and the waves can be triggered by earthquakes, volcanoes, and bombs - but also by daily human activity like travel and industry.

This quiet period was likely caused by the total global effect of social distancing measures, closure of services and industry, and drops in tourism and travel, the study published in the journal Science, reported.

The new research, led by the Royal Observatory of Belgium and five other institutions around the world including Imperial College London (ICL), showed that the dampening of 'seismic noise' caused by humans was more pronounced in more densely populated areas.

"Our study uniquely highlights just how much human activities impact the solid Earth, and could let us see more clearly than ever what differentiates human and natural noise," said study co-author Stephen Hicks from ICL in the UK.

For the findings, the research team looked at seismic data from a global network of 268 seismic stations in 117 countries and found significant noise reductions compared to before any lockdown at 185 of those stations.

Researchers tracked the 'wave' of quietening between March and May as worldwide lockdown measures took hold.

The largest drops in vibrations were seen in the most densely populated areas, like Singapore and New York City, but drops were also seen in remote areas like Germany's the Black Forest and Rundu in Namibia.

Citizen-owned seismometers, which tend to measure more localised noise, noted large drops around universities and schools around Cornwall, UK and Boston, US - a drop in noise 20 per cent larger than seen during school holidays.

The findings showed that countries like Barbados, where lockdown coincided with the tourist season, saw a 50 per cent decrease in noise.

"The changes have also given us the opportunity to listen in to the Earth's natural vibrations without the distortions of human input," the study authors wrote.

Earlier in April, a study published in the journal Nature, reported at least a 30 per cent reduction in that amount of ambient human noise since lockdown began in Belgium.

Bengaluru, Mar 15: The week-long ban imposed by the Karnataka Government from Saturday is yet to get a total response in the State to fight against the spread of killer disease Coronavirus (COVID-19).

The ban has witnessed a considerable reduction in the travelling public by Bus and train. Bus terminal and Railway stations wore desert look or only a very few public travelling. KSRTC, which was maintaining service for every 10 minutes once between the State Capital and to City of Palaces, was forced to cancel most of the service due to very little patronage. 

"We were left with no option but to cancel the fleet since there are no passengers," sources at the KSRTC Bus terminal told media persons.

Bengaluru, Apr 9: A special task force--set up by the government of Karnataka--submitted a report to the Chief Minister of Karnataka BS Yediyurappa, putting forward recommendations suggesting minimisation of restrictions in districts where there is nil or minimum cases, here on Wednesday.

The committee said: "COVID-19 and non-COVID-19 patients should be segregated and online health services should be encouraged. Restrictions should be minimised in districts where there is nil or minimum cases of COVID-19 and lockdown should be continued in hotspot areas with quarantine measures strictly being implemented."

With regards to the testing of likely patient, the committee informed that rapid test kits would help to quarantine more likely patient. "The rapid test kits will arrive in April 12. These kits will boost our facility and would help us in quarantining the more people."

On the subject of lifting transportation ban, the committee suggested that the transport of goods and services must continue but with regards to passenger carriers, they are suspended till April 30.

"Goods and Transportation should be allowed, but passenger carriers should be banned until further orders. No buses, trains nor flights will be plying till April 30. No metro trains and auto-rickshaws should be allowed and an odd-even system transport system should be implemented," the committee added.

The committee also suggested that all industries, IT, BT and Garments should be made to work on 50 per cent strength. Garments workers should be allowed to stitch PPEs, which are in more demand. And for construction workers, the committee suggested that they should be allowed to work at sites at 50 per cent strength.

They suggested that educational institutions remain closed till May 30 and online classes must be encouraged.

Dr. Devi Shetty heads the Taskforce and Dr. C. N. Majunath, Dr. Nagaraj, Dr. Ravi and Sudharshan were also the part of the committee.

According to the Ministry of health and family welfare, 181 cases have been reported in the state so far. A total of 5,734 positive cases have been reported of which, 166 are dead and 473 are cured/discharged and migrated.
