Data for the same earthquake reported by different agencies
Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.

Aftershocks
More info
Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 1259 km
2 (=486 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 61 km (38 mi).
Aftershocks typically occur during the weeks, months or even a year following the quake at or near the same fault, at distances of up to approx. two times the length of the rupture zone.
The often broadly linear arrangement of aftershock epicenters encompasses the rupture zone of the main shock (check on the
map below to verify).
