“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.”
A distanza di due anni dal terremoto, un tentativo di ricostruire la memoria sensoriale del trauma.
Essere massa interna. Per registrare il dato. In memoria.
