DEF

[An] instrument for recording the Earth's horizontal movements over a short distance during an earthquake.

OBS

Instead of a pendulum, the motion generated when this instrument was shaken by an earthquake came from the rotation of a small, copper, inertial mass (C) affixed to a thin wire under high tension (T), hence the name torsion seismometer.
