Why do earthquakes seem to roll?

    There are actually several types of earthquake waves, which are al gone over in detail in the attached link, but Love and Raleigh waves are types of surface waves that actually move the surface of the earth up and down like ripples on the surface of water; these are usually longer, so we really feel the up and down motion. There are other waves, some of which jolt and some of which simply shake back and forth.
