Do you know how Earthquakes Occur. Well what I'm going to tell you now is how they occur.
The Earth is made out of Plates.
Here is a picture of them.
Between the Plates are the Plate Boundaries. That is where Earthquakes occur.
Oh yeah and when a Earthquake happens, shockwaves go into plates but it get weaker when it goes further. That is why there are no Earthquakes in the UK
Here are signs of how a Earthquake is coming.
1. If you feel lots of Short Shakes, then a big one is going to come up
2. If there has not been a Short Shake for a while, then a big shake is coming your way
3. If animals act weirdly(e.g a dog houling), then a Earthquake is coming your way.
Remember this, it is 100% impossible to prevent a Earthquake, so if any of your signs are in your area, get prepared for a Earthquake!
EDIT : The Recent one in Haiti was in a Plate Boundary
