 1.crust gets pressure from plate movement and so on |
 2.Crust
2.microscopic chaps and radon releases |
 3.Radon which releases into atmosphere radiates and changes the 210Pb+ |
 |
 |
 |
|
4.Ion(radon and 210Pb+) is combined
earosol and gets bigger
|

 5.The ion which increses in size tall on the ground, and ion measurement instrument measures ion consentratim. |

6.After releaseing radon, crust keeps getting pressure
but when it cannot withstand strongpressure,
an earthquake happens
