The total number of quakes above magnitude 2 that occurred during the 3 days in the marked area was 3, 15% less than normally. This is compared to the average number (Ø) of 3.5 quakes obtained from the 100 preceding 3 days intervals with a standard mean deviation (σ) of 2.8 (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. In particular, there was a strong increase in smaller quakes of magnitudes around 3.

Mag	Total #	Ø	σ	Obs. deviation

4+	0	0	0	n/a
3+	2	0.4	0.7	+1.6	+456% (+2.4σ)

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
