| Synopsis | The evidence for Quaternary faulting in the Western Lowlands of Missouri and Arkansas consists of late Quaternary liquefaction features that are attributed to prehistoric earthquakes and to seismic-reflection profiles that show offset Quaternary reflectors.
These liquefaction features are evidence of strong shaking, but they do not identify the specific fault or faults that caused an earthquake or earthquakes. Because individual Quaternary faults remain unidentified, it is not possible to define and measure specific attributes (azimuth, length, dip, etc.) for the Western Lowlands liquefaction features. |
