Moscow: Black rain hits the city after a massive fire at an oil refinery

Arab Weather - The Russian capital, Moscow, witnessed an exceptional and unusual situation during the past hours, after recording rainfall accompanied by dark deposits on vehicles and surfaces, following a huge fire that broke out in an oil facility in the southeast of the city.

The scenes circulating from several neighborhoods have sparked widespread concern, with residents talking about what they described as “black rain”.

A massive fire broke out at an oil refinery, sending thick smoke billowing into the air.

According to media reports, the fire broke out inside an oil refinery in the Kaputania region, following a series of explosions whose causes have not yet been officially determined.

The fire caused thick columns of black smoke to rise, covering the sky over Moscow for hours, causing a noticeable decrease in air quality and visibility in some areas.

Reports of "black rain" and surface deposits

As the smoke continued to spread in the atmosphere, local residents reported seeing dark marks on cars and windows after light rain in some neighborhoods of the capital.

These scenes have led to the widespread use of the term “black rain” on social media, although there is no official confirmation of the nature of these deposits so far.

Growing environmental and health concerns

Environmental experts warn that the mixing of smoke from burning oil with rainwater could lead to several potential effects, most notably:

• High levels of air pollution
• Dark deposits on vehicles and surfaces
• Possibility of rainwater contamination with carbon particles
• Potential respiratory effects in sensitive groups
• Temporary disruption to local environmental quality
• Initial scientific interpretation

Experts believe the phenomenon is caused by raindrops mixing with fine particles of smoke and oil combustion, leading to a change in water color and the appearance of dark impurities.
