A bizarre formation was spotted in the skies of Helsinki, the capital of Finland Wednesday last week. The mesmerizing cloud formation appeared as a round hole in the sky.
The cloud formation sparked a lot of flurry suggestions not only from those who saw it but also from netizens. That includes the theory that there was an invisible UFO paying Earth a visit.
There were also some who feared that there is an apocalypse coming.
However, the Finnish Meteorological Institute released a scientific explanation saying that it was a result of ice crystal reaction with a cloud plate of droplets.
One of their meteorologists stated, “That cloud layer, which is now there, is about six to seven miles (10-12km) high, and the temperature is over 20 degrees frost (12 Fahrenheit). One explanation could be that if ice crystals come from above cloud layers, it causes very rapid liquid water freezing in ice crystals, where clouds will rain down and evaporate at the same time.”
This strange phenomenon is called “Fallstreak Hole.”
Not the First Incident
Last July 31, there was a huge sinkhole in Northern Sweden which forced the closure of a factory in the industrial area.
Hakan Wiberg from the Ornskoldsvik Emergency Services said that they had to cordon off the area for the fear of possible erosion since the hole grew to a size of eight-by-eight meters.
The hole was reportedly caused by a burst underground sewage pipe.
It is still not clear if the hole caused any damages to the building but experts are still investigating the matter.
These two incidents in Finland kept people wondering: Is this the result of abusing the environment? Is the environment paying back? What do you think?
