Adjust circle radius (50-2000 km):
The total number of quakes above magnitude 2 that occurred during the 7 days in the marked area was 9, 2% less than normally. This is compared to the average number (Ø) of 9.1 quakes obtained from the 100 preceding 7 days intervals with a standard mean deviation (σ) of 4.6 (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 7 days. Larger quakes of magnitude 5 or above have occurred more frequently.
