One seismologist says this earthquake is one of about seven or eight of this size or larger in the last one hundred years.
He explained the movement of the earthquake... and why a Tsunami warning was issued and then cancelled.
"This earthquake is an effect of the cascading obduction zone. The Juan de Fuca plates are slipping forward towards a future great earthquake but it also has very little chance of generating a tsunami because the blocks move side by side instead of up and down and it's the up and down motion that generates water motion for a tsunami," said seismologist Chris Goldfinger.
He also explains that sea level change may have some impact, but research is still needed to confirm that.
Goldfinger says it won't be surprising to see a future earthquake similar to this one in Southern California.
"The San Andreas fault is a culprit that everyone knows about; the southern half of it and the northern half of it seem to operate independently," explained Goldfinger.
"The southern half may well be a bit overdo, the northern half which is involved a little bit with this earthquake probably not overdue yet since we have the 1906 earthquake a bit over 100 years ago and the average repeat time for them may be in the neighborhood of 200 years. But definitely the southern part in the LA area is considered by most people to be either due or overdue."
So far, there are no reports of injuries from this earthquake.
