## Quakes within 30 degrees from seismic antipode up to 3 Tage after the quake

The area around the antipode is marked with the big circle on the map.
The total number of quakes that occurred within 3 Tage around the antipode of the quake was 0. This is compared to the average number of 0 quakes during preceding intervals of 3 Tage with a standard deviation (σ) of 0, calculated by analzing all 100 preceding intervals of 3 Tage for the same region.
