Short summary
An architectural element of the Royal Castle of Racconigi (northwestern Italy, 17th century) is subjected to nondestructive testing for structural integrity evaluation. It is found that the so-called acoustic emissions – high-frequency vibrations emitted as tiny cracks that develop inside stone and concrete – correlate with those of small nearby earthquakes, suggesting new approaches to monitoring gradual damage accumulation inflicted by such earthquakes on architectural heritage and monuments.
