The total number of quakes above magnitude 2 that occurred during the 7 days in the marked area was 18, 89% more than usually. This is compared to the average number (Ø) of 9.5 quakes obtained from the 100 preceding 7 days intervals with a standard mean deviation (σ) of 8.7 (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 7 days. Most notably, there was a strong increase in larger quakes of magnitude 5+.

Mag	Total #	Ø	σ	Obs. deviation
6+	1	0	0.1	+1	+9900% (+7σ)
5+	3	0.4	0.7	+2.6	+598% (+3.6σ)
4+	8	2.8	3.1	+5.2	+188% (+1.7σ)
3+	2	2.6	3.3	-0.6	-23% (-0.2σ)

All	18	9.5	8.7	+8.5	+89% (+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
