The total number of quakes above magnitude 2 that occurred during the 3 days in the marked area was 2, 83% less than normally. This is compared to the average number (Ø) of 11.5 quakes obtained from the 100 preceding 3 days intervals with a standard mean deviation (σ) of 53.3 (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.

Stop Russia's Agression - Support Ukraine
Significant parts of this website use brilliant open-source software developed by Ukrainians. Russia's unprovoked war has killed tens of thousands, displaced millions, and the beautiful country of Ukraine is being destroyed. We cannot be silent even if the topic of this website has nothing to do with politics.
If you like to support Ukraine from abroad:
Ukrainians recommend the Come Back Alive charity. For other options, see StandWithUkraine.
