- noun An instrument for automatically detecting and recording the intensity, direction, and duration of a movement of the ground, especially of an earthquake.
from The Century Dictionary.
- noun 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 (seeseismometer ) 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. - noun Same as
seismometer (which see).

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.
