Anything over 7.0 (usually anything even near it) is likely to have multiple 5.0+ pre- and/or after-shocks. (The Richter scale is a base-10 logarithmic scale meaning that a 6.7 is slightly less than 1/10 the amplitude of a 7.8.)

Worse, because the major earthquake tends to destabilize structures and foundations...aftershocks are often more deadly and destructive than the major earthquake of the tremor cluster.

Hopefully things settle down there soon. I can only imagine how long it will take them to recover from these.
