The total number of quakes above magnitude 2 that occurred during the 2 days in the marked area was 6, 80% more than usually. This is compared to the average number (Ø) of 3.3 quakes obtained from the 100 preceding 2 days intervals with a standard mean deviation (σ) of 2.4 (which is a measure of the typical amount of variation, or spread, of quake numbers during such a time interval).

Interpretation: There is a clear increase in detected quakes during the past 2 days. Most notably, there was a strong increase in larger quakes of magnitude 5+.

Mag	Total #	Ø	σ	Obs. deviation
6+	0	0	0.2	-0	-100% (-0.2σ)
5+	3	0.5	0.8	+2.5	+456% (+2.9σ)
4+	3	2.4	2	+0.6	+23% (+0.3σ)
3+	0	0.3	0.7	-0.3	-100% (-0.5σ)
2+	0	0	0.1	-0	-100% (-0.1σ)
All	6	3.3	2.4	+2.7	+80% (+1.1σ)

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
