## Quakes within 30 degrees from seismic antipode up to 24 Stunden 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 24 Stunden around the antipode of the quake was 0. This is compared to the average number of 0 quakes during preceding intervals of 24 Stunden with a standard deviation (σ) of 0, calculated by analzing all 100 preceding intervals of 24 Stunden for the same region.
Interpretation:
Note: At a magnitude of 3.1, 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 24 Stunden.
