Ion graph shows graph of atmospheric ion density and percentage. Above one is the density change of positive large ion, and blue broken line shows the change of positive large ion. The background shows earthquake danger forecast each day by colors. Please check next page(Explanation of an earthquake danger forcast). Below one is the percentage of positive large ion in all of positive ions(large, middle, and small) which is being measured.
