Quakes within 30 degrees from seismic antipode up to 3 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 3 days around the antipode of the quake was 29. This is compared to the average number of 25.24 quakes during preceding intervals of 3 days with a standard deviation (σ) of 40.5, calculated by analzing all 100 preceding intervals of 3 days for the same region.
Interpretation:
Note: At a magnitude of 3.2, it is unlikely that this quake could affect areas around its antipode. If an increase or decrease of quake is detected, it is likely caused by other factors.
There is no significant variation in the number of quakes that occurred around the antipode within 3 days.
