So even though it was quite a ways away the 6.4 quake that originated east of Bakersfield, CA about a third of the way to Vega only 40 minutes ago gave us a long slow rolling tremor here. Both the dog and I looked around at first trying to figure out what was happening.
If you haven't experienced this type of significant earthquake then it is interesting to know that eventually things in your house/office/store start making noise and you feel like you might be on a boat as things sway around you. The rattling was what made me realize it was an earthquake and this one seemed to go on a long time.
The type of earthquake like the Northridge quake we lived through in our prior S. Cal stay was a jolting feeling like a giant had picked up the house and dropped it from a short distance. That one sure jolted us out of our sleep.
Don't like them no matter how they move but no harm or damage from this one here. Just a bit too much adrenaline rushing through my veins.
Update: I just learned why it was a rolling quake sensation here thanks to the amazing Cal Tech geologist expert. She said that the rolling motion is caused by low frequency waves while the jolt is the high frequency. Low frequency ones travel much further than the high so you can know that it is pretty far away if that is what you feel. Good to know!
