Accelerograph

Definition

An accelerograph is a device used to record the motion of ground vibrations caused by seismic events, particularly earthquakes. It captures the acceleration of ground movement, providing vital data for understanding seismic hazards and characterizing ground motion. The information gathered helps engineers and scientists assess the effects of seismic activity on structures and the surrounding environment.
