Table 4.

Ground-truth used for validation of the relation between damage proxy inferred from InSAR data and the damage as function of peak-overpressure.

Number	Locality	Distance (km)	Est, damage	% of coherence loss (damage proxy)	Est. overpressure (kPA)	Computed damage proxy (%)
1	Sursock Palace	0.9	Partial demolition—partial collapse roof	59	7–15	44.4–61.8
2	Saint George hospital	1	Minor damage, partial demolition	47.9	8–15	47.5–61.8
3	Seaside Arena	1.1	Serious structural damage, collapse	61.5–74.3	18–40	66–84.1
4	Saint George church	1.4	Minor damage	58.9	7–15	44.4–61.8.75
5	Forum de Beyrouth	1.5	Metal buckled	52–60	7–15	46.3–61.8
6	Hotel Cavalier	3	Minor damage, buckling	None	3–7	28.26–36

See map of locations in Fig. 7. For each location the distance is given relative to explosion location and damage levels are estimated from available media coverage and reports^22,44,45.
