This link has a bunch of information on different scientific study techniques for earthquakes: http://earthquake.usgs.gov/research/topics.php

the Mohorovicic (Moho) discontinuity
By studying how seismic waves travel through the Earth's interior.
Generally increase with depth, occasionally making abrupt jumps termed seismic-velocity discontinuities.
A seismograph is an instrument that records movements within the earth. A seismogram is the actual recording that scientists look at when studying earthquakes.

the Mohorovicic (Moho) discontinuity
By studying how seismic waves travel through the Earth's interior.
Scientists determined that the Earth has layers through studying how seismic waves travel. These seismic waves differed depending on how thick the layer was.

seismic waves that travel through the earth
Using data from seismic waves geologists have learned that Earth's interior is made.
scientists use seismic waves to map earths interior by seismographs that measure the times at witch seismic waves arrive at different distances from an earth quake.
