The total number of quakes above magnitude 2 that occurred during the 3 days in the marked area was 7, 17% less than normally. This is compared to the average number (Ø) of 8.5 quakes obtained from the 100 preceding 3 days intervals with a standard mean deviation (σ) of 7.4 (which is a measure of the typical amount of variation, or spread, of quake numbers during such a time interval).

Interpretation: There is a weak increase in detected quakes during the past 3 days. Most notably, medium quakes of magnitudes around 4 have occurred more frequently.

Explanation:

BLACK = Number of quakes within normal statistical range

RED = Significantly lower than normal number of quakes

GREEN = Significantly higher than normal number of quakes
