The Grotta Gigante horizontal pendulums are a pair of tiltmeters used for monitoring Earth movements, mounted in the Grotta Gigante in Italy. The horizontal pendulums, installed by the geodesist Antonio Marussi in 1959, are sensitive to deviations of the vertical, to rotations and shearing of the cave.
