Quakes within 30 degrees from seismic antipode up to 2 days 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 2 days around the antipode of the quake was 0. This is compared to the average number of 0 quakes during preceding intervals of 2 days with a standard deviation (σ) of 0, calculated by analzing all 100 preceding intervals of 2 days for the same region.
Interpretation:
There is no significant variation in the number of quakes that occurred around the antipode within 2 days.
