A weird cloud phenomenon was observed above Costa Rica on September 15th 2015. The cause of this phenomenon remains unknown.
This strange cloud phenomenon was seen around 3.00 pm local time and it was caught on camera by a witness.
This strange cloud could also be an earthquake light. The earthquake light appears before and even after an earthquake.
They usually appear in the wide color spectrum, but mostly range from white to bluish hue.
Alternative explanations include intense electric fields created piezoelectrically by tectonic movements or even by the disruption of the Earth’s magnetic field.
