[edit] Geophone vs. seismometer

This article needs to distinguish between geophones and seismometers. I believe that a geophone is best described as a type of seismometer. Features that I believe separate them from other types of seismometers are:

  • Size: geophones are small.
  • Sensitivity: geophones are designed to record locally generated events, not teleseismic events.
  • Bandwidth: geophones have a bandwidth (on the order of 5-200+ Hz) higher than earthquake seismometers.
  • Portability: geophones are designed to be picked up and moved quickly and roughly.
  • Separation of sensor from recorder: geophones are meant to be connected and disconnected at will from data recording systems via electrical or optical connectors.
  • Application: geophones are designed to be laid out in patches for unaliased recording of wavefields. EQ seismometers are generally designed for point recording.

Please note any thoughts here. GeoGreg 21:15, 31 January 2007 (UTC)
