How does the flat earth explain seismographs of earthquakes when they're on the opposite side of the Earth (according to RE)? Here's a good explanation on the phenomenon if you do not understand: http://www.indiana.edu/~geol105/images/gaia_chapter_3/seismic.htm

This too: http://www.bbc.co.uk/schools/gcsebitesize/science/edexcel/waves_earth/seismicwavesrev3.shtml

Also, why do the seismic waves from quakes seem to be blocked by a solid object in the center of the Earth? In the RE, this is the solid iron core. What explains this occurrence for a FE?
