It was an unusual day for citizens in Indonesia as they witnessed a ‘blood red sky’ over the region on 23rd September due to the forest fires. The blood red haze occurred over the region due to the interaction of the sunlight on particles from smoke in the air, which is also known as the Rayleigh scattering.
This unusual occurrence generated a buzz on social media, with many sharing pictures and videos of the “blood red” sky that caused panic among the locals.

You see, slash-and-burn farming techniques in this country is often the cause of forest fires but the situation aggravated due to El Nino (unusual winds that cause warm surface water from the equator to move east towards Central and South America).

However, the haze caused by land clearing fires this year was among the worst the country had witnessed till date. A state of emergency has been declared in 6 provinces due to the same.
This was certainly a phenomena that you don’t get to witness every day and even netizens couldn’t believe what they were seeing.

Red sky seen in #Jambi, Indonesia. What you’re seeing is Mie scattering/ Reyleigh scattering. The reason this is happening is due to toxic pollution which is 153% higher than what is typically considered to be toxic air pollution. We have screwed this

~The Door of Another World~
WTH is that? Another Japanese novel with #isekai genre?
No. This is a door from a certain village in Jambi, Indonesia.
The red sky is not photoshopped, but a real nightmare because of very thick haze from Forest Fire. pic.twitter.com/kfthXxE7zz
Like the Amazon, #Indonesia is undergoing a #fire crisis.

Much of it is from burning to clear land. #RedSky #IndonesiaForestFireCrisis https://t.co/pysHuS4Pt5
Such a weird phenomenon. Aerosols emitted from wildfires (and possibly pollution) have been blamed for #redsky in Jambi, Indonesia. Still, it’s totally unbelievable. It’s like Martian atmosphere on Earth. https://t.co/yUt2G5V0CF
