Maybe the Russians and/or Chinese have copied the HAARP array and just sent a strong message to D.C.

Is the that not the info under the science and tech tab?
Data for Quaternary faults, liquefaction features, and possible tectonic features in the Central and Eastern United States, east of the Rocky Mountain front
Table 2. Summary of Quaternary faults, liquefaction features, and deformation in the Central and Eastern United States. [ID Number refers to the number assigned to the structure in the fault compilation and the digital database. "Time of MRE" is time of most recent paleoevent; see the definition of terms in this report for explanation of the time of most recent event and the slip-rate category. For liquefaction features, the slip-rate category is described as "unknown" because the faults that generated earthquakes at these sites have not been identified or characterized, and therefore it is impossible to determine a slip rate. General locations of features are shown in figure 1.] Structure Name (listed alphabetically) Location ID No. Time of MRE Slip-Rate Category Comments Bluffton liquefaction features South Carolina 2658 Latest Quaternary unknown Prehistoric liquefaction features southwest of the liquefaction from the 1886 Charleston, South Carolina, earthquake.

2653, Central Virginia seismic zone (Class A) Structure Number 2653 Structure Name Central Virginia seismic zone (Class A) Comments: The Central Virginia seismic zone was named by Bollinger (1973 #1797; 1973 #1798). It is a roughly circular area with a diameter of 120-150 km, with a low level of diffuse seismicity, three-quarters of which is in the upper 11 km of the crust (1985 #1801). Synopsis: The geologic evidence for Quaternary faulting in the Central Virginia seismic zone consists of one site with a few, small, latest Holocene sand dikes, and a second site several tens of kilometers away with a few, small, possible dikes of early Holocene or lesser age (Obermeier and McNulty, 1998 #1872). The causative faults remain unidentiﬁed. Date of compilation 05/21/98; revised 9/11/98 Compiler and afﬁliation Russell L. Wheeler, U.S. Geological Survey State Virginia County Amelia; Buckingham; Caroline; Chesterﬁeld; Cumberland; Fluvanna; Goochland; Hanover; Henrico; Louisa; Orange; Powhatan; Richmond; Spotsylvania 1° x 2° sheet Richmond; Roanoke; Washington; Charlottesville Physiographic province Piedmont Reliability of location Poor Comments: The largest historical earthquake in the zone occurred in 1875 near the center of the zone (Oaks and Bollinger, 1986 #2216). Intensity was MMI VII and magnitude was mb 5.0 and M 4.8 (Bollinger and Hopper, 1971 #1799; Bollinger and Sibol, 1985 #1801; Johnston, 1994 #2042). No surface rupture or liquefaction is reported. Similarly, no prehistoric surface rupture is known in the seismic zone, and the only reported paleoliquefaction features are those few described below under "Paleoseismological studies". Hypocenters of microearthquakes plot within an upper crustal complex of thrust sheets (Çoruh and others, 1988 #1807), but the locational uncertainties of both the hypocenters and the individual thrust faults are typically a few kilometers. Therefore, hypocenters and faults cannot be convincingly associated with each other. The result is that the individual seismogenic faults in the Central Virginia seismic zone remain unidentiﬁed. Geologic setting The Central Virginia seismic zone is underlain by Precambrian and Paleozoic metamorphic and igneous rocks that were folded, juxtaposed, and superimposed by numerous nappes and thrust faults, mostly southeast-dipping, during the assembly of the Appalachians (for example Glover and others, 1983 #1827; Glover and others, 1989 #2034; Hatcher and others, 1989 #2036). Sense of movement Not reported Comments: Single-earthquake focal mechanisms from the seismic zone are variously oriented and show reverse and strike-slip faulting (Munsey and Bollinger, 1985 #1867; Davison, 1988 #2027). However, the associated hypocenters are scattered geographically, and no surface ruptures are known, so no systematic sense of movement is known
