That link hasn't got any from right when he felt them, though. Might have been something else. The ones around Lassen have been tiny. Every so rarely often, Redding gets a quake worth noticing. I was there for one, but it was centered near Oroville.
Feeling earthquakes from where they happen is quite different for people. I had been on the epicenter of one and didn't really feel it, then other times I am miles away from an earthquake and it shook me right off the sofa.
It also depends a lot on soil type, depth of the hypocenter, and the geology between the epicenter and where it's felt. That's why there could be so much damage in the Santa Cruz mountains, Los Gatos, Palo Alto, San Francisco, and Oakland, but less in Hayward and Fremont. Geological structures underground actually bent and deflected waves in some places, amplified them in another.
John McPhee's "Assembling California" does a good job of explaining it. I get hot and bothered about such things.
