The total number of quakes above magnitude 2 that occurred during the 3 days in the marked area was 81, 139% more than usually. This is compared to the average number (Ø) of 33.9 quakes obtained from the 100 preceding 3 days intervals with a standard mean deviation (σ) of 22.7 (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 3 days. Most notably, medium quakes of magnitudes around 4 have occurred more frequently.
