Recently, the SGs, and broadband three-axis seismometers operated in gravimeter mode, have begun to detect and characterize the small gravity signals from earthquakes. These signals arrive at the gravimeter at the speed of light, so have the potential to improve earthquake early warning methods. There is some activity to design purpose-built ...
Gravimeter with variant of Repsold pendulum The large increase in gravity measurement accuracy made possible by Kater's pendulum established gravimetry as a regular part of geodesy . To be useful, it was necessary to find the exact location (latitude and longitude) of the 'station' where a gravity measurement was taken, so pendulum measurements ...
William Chester Minor (also known as W. C. Minor; 22 June 1834 – 26 March 1920) was an American army surgeon, psychiatric hospital patient, and lexicographical researcher. After serving in the Union Army during the American Civil War , Minor moved to England.

The Lunar Traverse Gravimeter was a lunar science experiment, deployed by astronauts on the lunar surface in 1972 as part of Apollo 17.The goal of the experiment was to use relative gravity measurements to infer potential attributes about the geological substrata near the Apollo 17 landing site.
The entire work, except the coda, consists wholly of semiquaver (sixteenth note) arpeggios, spanning large lengths of the keyboard in the space of one bar. The initial theme is expounded upon and changes to many different keys. The climax resolves to C major.
During the Classical era, C minor was used infrequently and often for works of a particularly turbulent cast. [citation needed] Mozart, for instance, wrote only very few works in this key, but they are among his most dramatic ones (the twenty-fourth piano concerto, the fourteenth piano sonata, the Masonic Funeral Music, the Adagio and Fugue in C minor and the Great Mass in C minor, for instance).
A pendulum can therefore be used as a gravimeter to measure the local gravity, which varies by over 0.5% across the surface of the Earth. [107] [Note 2] The pendulum in a clock is disturbed by the pushes it receives from the clock movement, so freeswinging pendulums were used, and were the standard instruments of gravimetry up to the 1930s.
