11. By such analyses of seismograms the Earth's core was located in 1913 by Beno Gutenberg. 12. For modern earthquakes, moment is usually estimated from ground motion recordings of earthquakes known as seismograms . 13. Thus larger earthquakes give longer seismograms [ as well as stronger seismic waves ] than small ones. 14. After the digital processing has been used, the archives of the seismograms were recorded in magnetic tapes. 15. It's a seismogram , a record of seismic waves recorded by a seismograph 16 miles from the blast. 16. It can automatically plot seismograms from 18 seismic signal sources and 3 time signals on a continuous reel of film. 17. The energy measured in a seismogram may result from an earthquake or from some other source, such as an explosion. 18. A series of apparently related reflections on several seismograms is often referred to as a " reflection event ". 19. Multipoint geostatistics, completions modeling, automated fault polygon generation and a new synthetic seismogram package called Seismic-Well-Tie 20. Reflection seismograms record the reflection wave along the propagation path r from the source to reflector and back to the surface.
