The third intervention, CORAL, COLLECTIVO, TECTÓNICO, is a sound installation created by Chilean artist Constanza Alarcón Tennen. It is based on personal auditory memories of earthquakes and their effects. The work is an ongoing sound archive consisting of audio recordings of people using their own voices to reproduce the sound of an earthquake they had experienced at some time. Constanza Alarcón Tennen arranges this archive of recorded voices into a composition, which she then makes tangible in the public space on the campus grounds by means of a vibrating wooden structure that serves as an oversized tactile loudspeaker.
