Most of the energy in the long period looks to be in the <45 second

A few times the question has come up about which events can be seen=20

I've set up a page with images of the broad-band station COR, which=20
is run by the USGS
and Oregon State University:

Clicking on this image toggles between short-period- and=20
long-period-filtered versions.



Hi John,

       Not many of us have instruments which go to 1000 sec. Can you
show us what the 10 to 40 sec band looks like in comparison, please?

       Regards,
