"Spacequakes"

"Spacequakes" are strong vibrations in the planets magnetic field that can have an affect on auroras and also cause "space twisters". The sun constantly emits energy into the Earth's magnetic field lines causing the energy to build up. When there is too much energy built up in the field lines the line snaps like a rubber band. When the line snaps part of the line comes to Earth collecting high-energy particles from the Earth's atmosphere and creates a "plasma jet". The jet smashes into other parts of the Earth's magnetic fields and continue until there is no energy left in the jets. When the jets bounce on the Earth's other atmospheres they create as much energy as a level 5 or 6 earthquake. Although we don't feel these "spacequakes" they do affect the earth. One affect they can have on Earth is by creating bright lights and swirls in auroras in the North and South Poles. This is not particularly dangerous but more enjoyable. They can also bring down power grids which affect large areas. This effect is more troublesome than enjoyable.

This is science related because it explains what happens in the Earth's atmosphere. "Spacequakes" happen daily, almost every 4 hours, and major "spacequakes" happen about once a year. Studying "spacequakes" could give answers to unexplained power outs and why some auroras are so big, bright, and beautiful. While studying "spacequakes" we might find out the answers to some unexplained mysteries that exist.

"Spacequakes" aren't something to be hugely concerned about. The most to be concerned about with "spacequakes" at this time are power grids failing, and even if power grids do fail these quakes happen in the atmosphere. So, even if they do happen every 4 hours it's not certain where they will or will not affect. They could affect some parts of the United States or somewhere on the other side of the world in Japan. While scientists are studying these "spacequakes" we might as well enjoy the pretty patterns they make in auroras and maybe be prepared for a temporary blackout.
