The path dedicated to the earthquake understanding explains the physical phenomenon and its effects by studying in depth the structures behaviour under seismic shaking.

The historical evolution of the seismic instruments of measure is described from the Chinese seismoscope by Zhang Heng (132 A.D.) to the modern earthquake monitoring systems. Within the exhibition, the Italian seismic warning system is reproduced (“monitoring room”). It consists of three national networks: the INGV Seismometric Network, the DPC Strong Motion Network (RAN) and the DPC Seismic Observatory of Structures (OSS). In the monitoring room, the Seismometric Network is provided with a screen that displays the earthquake platform, a system which processes in real-time the signals coming from the seismic stations and calculates the main earthquake parameters (epicentre location, magnitude, depth). The RAN is equipped with a screen that displays the signal measured by a sensor set on the ground and triggered by visitors walking. The OSS is provided with a screen that displays the signals recorded by two accelerometers positioned on the party walls, which reproduce the accelerometric monitoring of the structure housing the exhibition.
