ABSTRACT: Dimensional coherence is a measurable property of space characterized by a uniform bond between the observable information of our reality and the substrate upon which it is projected. Dreadpoint zones of imperfect cohesion between these layers produce localized instability, yielding unpredictable and anomalous events. This survey was established in 1962 using standardized global seismic instrumentation and subsequently incorporated satellite imaging, continuous digital monitoring, and high-resolution geodetic measurements as these capabilities became available. To date, eleven locations have been identified that exhibit measurable degradation in coherence across a range of geological and geomagnetic contexts, none of which show convergence indicators during the measurement period. None of the observed degradation profiles correlates with any single variable or combination of variables sufficient to model convergence-threshold conditions. These data are consistent with the involvement of catalytic factors not represented in the current measurement framework. The survey continues with instrumentation under review.
