American Heritage® Dictionary of the English Language, Fourth Edition
- n. An instrument for automatically detecting and recording the intensity, direction, and duration of a movement of the ground, especially of an earthquake.
Century Dictionary and Cyclopedia
- n. Same as seismometer (which see). The more complicated forms of instruments contrived for the purpose of recording the phenomena of earthquakes are sometimes called
seismographs, and sometimes seismometers. The name seismograph was first employed in reference to the elaborate seismometer contrived by Palmieri and used at his station on Mount Vesuvius. This was called by him a “sismografo,” and this name has generally been Englished as seismograph, which is also the designation most generally applied by the members of the Seismological Society of Japan to the seismometers there contrived and used within the past few years.
- n. See seismometer. A great variety of apparatus has been devised for recording earthquake phenomena, of which that perfected by Omori is used in Japan, that of Milne is established at about fifty British and international stations, and that known as the Bosch-Omori, improved by Marvin, is used at about thirty American and German stations. All these are adaptations of the horizontal pendulum at first used by Zollner in 1860 to investigate changes in terrestrial gravity, and they record the horizontal movements of the ground at great distances from the origin of the earthquake. A very different apparatus for this purpose is the inverted vertical pendulum devised by Wiechert (see seismometer) and greatly improved by Marvin at Washington. No apparatus for recording vertical movements of the ground and none for recording the largest movements near the epicenter have as yet been successful.
- n. An instrument that automatically detects and records the intensity, direction and duration of earthquakes and similar events.
GNU Webster's 1913
- n. (Physics) An apparatus for registering the shocks and undulatory motions of earthquakes.
- n. a measuring instrument for detecting and measuring the intensity and direction and duration of movements of the ground (as an earthquake)

“The point we are making here is that if we regard the equity markets as a long-term seismograph of the economy, then so far, despite all the storm and stress, the markets - and therefore the economy - remain within the general pattern of the 2000-2002 market at the 2001 recession.”
