“Inertial seismometers have levers in them that keep rhythmic motion. A weight, usually called the internal mass, that can move relative to the instrument frame, but is attached to it by a system (such as a spring) that will hold it fixed relative to the frame if there is no motion, and also damp out any motions once the motion of the frame stops.
A means of recording the motion of the mass relative to the frame, or the force needed to keep it from moving.”
Two years after the earthquake, Massa Interna is an attempt to reconstruct the sensory memory of the trauma.
Be internal mass. To save the data. In memory.
