Why does it show up on Seismographs on another  continent?

Why not. This is one mostly-solid ball of rocky stuff, and energy (seismic  
waves, for example) can be transmitted through that stuff.

  What do the colors  mean?  

Each line across the seismogram  represents 15 minutes. Different colors 
make "counting" the lines easier. Each  cycle of 4 colors represents 1 hour.
