The total number of quakes above magnitude 2 that occurred during the 3 days in the marked area was 24, 9% less than normally. This is compared to the average number (Ø) of 26.4 quakes obtained from the 100 preceding 3 days intervals with a standard mean deviation (σ) of 22.1 (which is a measure of the typical amount of variation, or spread, of quake numbers during such a time interval).
Interpretation: There is no significant variation in the number of quakes that occurred during the past 3 days.
