Dictionary:Earthquake seismology

{{#category_index:E|earthquake seismology}} Study of earthquakes and their resulting seismic waves as a means of understanding the structure of the Earth. A schematic seismic record showing several of the wave arrivals from an earthquake is shown in Figure E-3. The scheme for identifying different arrivals is discussed under wave notation (q.v.). The time intervals between different arrivals depend upon the distance from the earthquake hypocenter to the observing station; see Jeffreys-Bullen curves.
