Not scared of Pakistan's nuclear bogey, says Lieutenant General Naravane

Noida, Jan 6: A fire broke out at the ESIC Hospital in Noida on Thursday morning and firefighting was underway, officials said.

The blaze broke out in the basement of the seven-storey hospital building located in Sector 24, a police official said.

Fire tenders were rushed to the spot after the Fire Department was alerted about it around 8 am, the official said.

After that, a search was done to see if anyone was trapped in the building, he said.

The cooling process is now underway.

He said the fire had engulfed the ground, first and second floors of the building, except the basement.

Police said they received information about fire at Kaveri printing press at 2:45 am, when the manager Yogesh called them. The press owners have been identified as Atul and Anuj Goyal, residents of Sukhdev Vihar, they said.

The man who died in the fire has been identified as Phool Dev, from Bihar, who used to work as a help there. Dev went inside the building in the night to sleep before the fire started and died due to suffocation, the fire department official said.

The body has been kept at Lal Bahadur Shastri Hospital and the post-mortem will be done once the family reaches here, police said.

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

New Delhi, May 10: A medium-intensity earthquake of 3.4 magnitude hit Delhi on Sunday.

According to the National Center for Seismology (NCS), the quake occurred at 1.45pm at a depth of five kilometres.

There were no immediate reports of loss of life or property.
