Accelerometer

Definition

An accelerometer is a device that measures the acceleration forces acting on it, providing data about the motion and orientation of an object. These devices are crucial for understanding seismic activity, as they help detect ground motion caused by earthquakes and can provide insights into the intensity and duration of seismic waves, which in turn influence how landscapes are shaped and modified during and after such events.
