D8 Power reconstruction using damage analysis and remote sensing

Topic

Retrospectively estimating the yield of a past detonation relies on combining several lines of evidence—each previously established in this catalog. Comparing the observed pattern and severity of structural damage against the vulnerability curves for specific building types (as defined by the structural damage model) makes it possible to infer the overpressure levels reached in various zones. Satellite and aerial analysis of large-scale urban damage patterns allows for the systematic mapping of the damage's geographic extent—a feat that ground-level inspection alone could not achieve with comparable coverage.

Added to these two approaches is retrospective dosimetry of construction materials exposed to the event's initial radiation—the same technique described in this catalog’s physical dosimetry model.

Consequently, this model—which integrates mechanical damage, geographic extent, and residual dose—yields a more reliable yield estimate than any single line of evidence could provide on its own; it employs the same triangulation approach used in historical studies of past events and in verification and intelligence work regarding contemporary nuclear tests or incidents.
