Scaling
fist-sized; thicker than flaking
Assessment Test
Weakness of the Edifice/Facade/Dressed Stone
Impending or Future Loss
Other Forms of increment erosion
(e.g., insects, birds)
Splintering (Small Erosion)
following stone structure and oblique to stone surface
Natural Process Type
Other Natural Causes of break off
wedgework of roots, earthquakes, intersection of fractures, ...

Loss parallel to stone structure
layers "peeling" from stone surface parallel to bedding plane

Seismic Classification According to the Dipartimento della Protezione Civile (2019), http://www.protezionecivile.gov.it/attivita-rischi/rischio-sismico/attivita/classificazione-sismica (on a scale of 1 - 4, with 1 representing the greatest risk for strong seismic activity)
Changes in textural anomolies
