“…13): 1A-Underground liquefaction and fluidization of sediments beneath the confining layer; 1B-Increasing pore-pressure triggering sediment intrusions and surface upwarping (bulging); 1C-Strong pore-pressure under upwarped confining layer triggering its hydraulic fracture along with abrupt sand and gravel ejection, to generate sand explosion craters. Phase 1A constitutes classical liquefaction of a potentially liquefiable layer, overlapped by a confining, or partially confining, layer as in the case of craters described by Amick et al (1990) and Amick and Gelinas (1991). Phase 1B is characterized by intrusion of liquefied sand in overlaying sediments.…”

“…Explosion craters protruded from the ground surface, generating elevated rims and subsequent radial and circular ground cracks, their elevations an indication of the approximate maximum ground up warping. Amick et al (1990) describe 15-20 cm thick rim deposits around craters generated during the AD 1886 Charleston earthquake (X MM; 7.0 Mw; USA) in response to widespread liquefaction and multiple sand venting in the Mississippi floodplain. These types of ephemeral deposits are poorly preserved in the geological record.…”

“…By calibrating geologic observations of sandblows in the Charleston region with those features associated with the 1886 event, the investigators have been able to identify pre-1886 sandbio_ s and to date them (e.g., Obermeir et al, 1987;Talwani and Cox, 1985;Amick et al, 1989).…”

Dotted pattern denotes earthquake ages determined from multiple liquefaction :dtes. Striped pattern denotes earthquake ages based on dates from only one liquefaction site. Arrows indicate the probable occurrence of at least one older liquefaction episode in both the Charleston and northern areas. (From Amick et al., 1989.) 7.
