a sostegno della perplessità espressa da mccoy,
che condivido come privatamente discusso, riporto di seguito un passo delle conclusioni tratte da De Luca et alii nel lavoro del 2005 cui si fa riferimento.

Quote:

Because of the characteristics of the buildings found in
the
investigated area, mainly old masonry buildings, the low frequency
amplification does not really affect their behavior
during earthquake
shaking. This consideration does not hold
for new expansion areas,
residential and industrial, where
some tall concrete buildings have
recently been constructed."
