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)

Notations on Rock Coatings
Assessment Test
Date assessment was performed
Assessment Date
Natural Process Type
Natural processes that are a major concern to you
Rock Type
Assessment Test Score Value
from sediment transport by water; plants rubbing; people leaning/scratching on facade
Abrasion
honeycombed appearance
Alveolization
Anthropogenic Activities
carving, chiseling, bullet impact...
Anthropogenic Cutting
mortar work
Anthropogenic Fissures
Anthropogenic Joints/Joining
chalking, graffiti, exhaust, dust, other
Anthropogenic Rock Coating
showing on the stone surface, NOT part of rock
Carbonate
hardened outer shell
Case Hardening
(banding, concretions)
Changes in textural anomolies
bedding, foliations
Fissures Dependent on lithification
in groups of grains or powdery
Crumbly disintegration
frequently sandstone and granite
Granular Disintegration
Droppings
Dust Coatings
Fire
Fissuresol
calcrete wedging, dust in fissuresol, or both
Fissuresol (Large Erosion)
single or multiple - centimeter to a few inches in size
Flaking
Graffiti
pressure release, calcrete wedging
Fissures Independent of stone lithification
Iron Film
(e.g., livestock, off-road vehicles)
Land use issues
Lithobiont pitting
e.g., lichen
Lithobionts
layers "peeling" from stone surface parallel to bedding plane
Loss parallel to stone structure
(e.g., water flow, pollution, foot traffic, etc.)
Other concerns
(e.g., insects, birds)
Other Forms of increment erosion
wedgework of roots, earthquakes, intersection of fractures, ...
Other Natural Causes of break off
Other Vandalism
rusting on the stone surface
Oxidation
Plant growth near or on facade
Pollution
banding, concretions
usually incomplete; includes paint material and "leafing" in inscriptions
Rock Coating Detachment
Rock Coating Present
desert varnish
Rock Varnish
Modified Moh's Hardness: 0 = quartz scratch/can't scratch; 1 = knife blade scratch; 2 = penny scratch; 3 = fingernail scratch
Rock Weakness
Roots
Rounding and/or blurring of carved edges or inscriptions
Salt efflorescence or subflorescence
future location of centimeter to half meter size diameter
Scaling and Flaking
fist-sized; thicker than flaking
Scaling
following stone structure and oblique to stone surface
Splintering
Splintering (Small Erosion)
clay lenses, cementation differences, nodules
Textural anomoly features erode differentially
Trash
larger than scaling
Undercutting
Undercutting (Large Erosion)
e.g., dust, road proximity
Visitor Impact
Weathering-rind development
