I'm a bit mystified why people seem surprised at normal aftershock activity.
Perhaps if Oregon has a 6.0 in the next few days people will be really rattled. All those expensive beach houses from Florence to Lincoln City are right down on the beach. Miles from higher ground all of them, with no protection at all in any direction. Totally exposed to tsunamis.
Oh, well, not for me to worry.
I, too, am mystified by people's reactions. It has been relatively quiet for a few years up here on the north coast of California. The activity we are seeing now is not really unusual for this area.
I think access to the web and 24 hour news exaggerates events like this. I live on Humboldt bay which is about a close as one can get to the two northern earthquakes and it didn't even rattle the dishes.
Well, So CA has been relatively quiet since the Northridge quake in 1994....(and Landers/Big Bear twin quakes in 2002)
or the last major in No Cal in 1989...
The majority of the people that survived those quakes are probably gone. (with a 7% turnover per year)
