You can both have the pen pointing horizontally, and the paper mounted vertically, or attach the pen so it is vertical and have it pushing very gently down on the horizontal paper.
Earthquake hypocentres are most typical within the depths of zero to 70 kilometres. Less common are earthquakes having hypocentres in great depths, of as much as 700 kilometres. These occur primarily where resulting from sluggish drift of the tectonic plates the crust of plate edges is pushed down, as is the case, for example, of the South American Andes.
