Witnesses felt buildings shaking along the California coast but there were no immediate reports of damage.
A tsunami warning was briefly in effect from the California-Mexico border, north to Vancouver Island, British Columbia, but was called off about an hour after the earthquake was felt.

humm, i thought only earthquakes of magnitude 7.9 or higher could create big tsunamies.
Anyways, anyone living in that area should keep an eye on the news.

I dont thinks size matters as long as there is a displacement of land on the ocean floor, or a landslide.
Magnitudes below 6.5
Earthquakes of this magnitude are very unlikely to trigger a tsunami.
Magnitudes between 6.5 and 7.5
Earthquakes of this size do not usually produce destructive tsunamis. However, small sea level changes may be observed in the vicinity of the epicenter. Tsunamis capable of producing damage or casualties are rare in this magnitude range but have occurred due to secondary effects such as landslides or submarine slumps.
Magnitudes between 7.6 and 7.8
Earthquakes of this size may produce destructive tsunamis especially near the epicenter; at greater distances small sea level changes may be observed. Tsunamis capable of producing damage at great distances are rare in the magnitude range.
Magnitude 7.9 and greater
Destructive local tsunamis are possible near the epicenter, and significant sea level changes and damage may occur in a broader region.
