Why does it show up on Seismographs on another continent?  What do the  
colors mean?

The  Chilean earthquake is clearly visible on the seismographs  in
Yellowstone.  The earthquake was at 2334 local and was noted at  Old
Faithful at 2342.  All seismograph (Webicorder displays)  throughout the
inermountain west look about the  same.
