The total number of quakes above magnitude 2 that occurred during the 3 days in the marked area was 7, 29% less than normally. This is compared to the average number (Ø) of 9.9 quakes obtained from the 100 preceding 3 days intervals with a standard mean deviation (σ) of 3.4 (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.

Mag	Total #	Ø	σ	Obs. deviation
6+	0	0	0.1	-0	-100% (-0.1σ)
5+	0	0	0.2	-0	-100% (-0.2σ)
4+	1	0.7	0.9	+0.3	+47% (+0.4σ)
3+	2	3.5	1.8	-1.5	-44% (-0.9σ)
2+	4	5.6	2.4	-1.6	-29% (-0.7σ)
All	7	9.9	3.4	-2.9	-29% (-0.8σ)

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
