Aftershocks of the 6.8 quake East of the Kuril Islands (Russia) 1969-08-12 05:53 UTC
More info
Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 631 km
2 (=244 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 44 km (27 mi).
Aftershocks typically occur during the weeks and months 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).
