La descrizione dei danni della Zona 3:
damage by falling on roofs and breaking windows. Deep dust of 0.5 inches (10mm) is possible
within this zone, resulting in mechanical damage (e.g. clogging to air conditioners) and damage to equipment and finishes. Electrical power outages, lasting at least 5 days, extend into this zone.
Media reports also suggest that building damage extends into this zone, although the frequency and severity of the damage will only emerge with full professional surveys."
