June 1, 2012 - June 2012 Earthquake Quantity and Power 10X Forecast: This forecast is based on 5,311 actual earthquakes, from 1973 to 2011, greater than or equal to 6.0 magnitude. These quakes were downloaded from the USGS and summarized by year, month and day. The graphs you see above reflect the quantity per day and power 10X forecast for the month of June 2012.
For example, for the 1st of June a total quantity of 11 quakes occurred over 39 years; with a combined power 10X rating of 24. The quantity is a simple summation of all the earthquakes that occurred on June 1st for the 39 year period from 1973 to 2011.
The Power 10X rating is based on the logarithmic nature of the Richter scale (a ten based system). This means that a 7.0 magnitude quake is ten times stronger than a 6.0 magnitude quake. An 8.0 magnitude is 100 times stronger than a 6.0M (10 X 10 = 100). A 9.0 magnitude is a thousand times stronger than a 6.0M (10 X 10 X 10 = 1,000).
For example, June 11th and 12th have the same quantity at 13 each. However, the power 10X rating is significantly different between the two days. June 11th has a power 10X rating of 46, while June 12th is rated at 100. This means that the quakes occurring on June 12th were significantly stronger than those that happened on June 11th.
Therefore, the most dangerous days in June are the 9th at 203 and the 23rd at 306.
