Review of Recent Research on the Seismotectonic of the Southeastern Seaboard and an Evaluation of Hypotheses on the Source of the 1886 Charleston, South Carolina, Earthquake.

摘要

In spite of extensive research on the source of the 1886 Charleston, S.C. Earthquake, there is not yet a consensus among earth scientists on the characteristics of the fault that produced the earthquake or on the likelihood of future large earthquakes at other locations of the Southeastern Seaborad. The report reviews the evidence from recent research on three categories of hypothesis: (A) hypotheses on the specific geologic structures that might cause large earthquakes in the Southeastern Seaboard: (B) hypotheses on the seismotectonic zones in which large earthquakes might occur; and (C) hypotheses on temporal variations of seismicity in the Southeastern Seaboard. Hypotheses that are representative of each category are summarized, and evidence for and against each hypothesis is given, if such evidence is available.
