Quick Answer
A seismometer is the sensor that detects ground motion; a seismograph is the broader recording instrument.
The Full Story
In modern usage, seismometer usually refers to the sensing component that measures motion from an earthquake. It works by comparing a suspended mass to the moving ground, allowing even small vibrations to be detected. Seismometers are used in seismic observatories, boreholes, and even on the Moon and Mars. Their data are essential for earthquake science and for monitoring volcanic and industrial vibrations.
