Goldfinger et al. (2008) conclude that in the northern San Andreas fault and Cascadia margins, Holocene turbidites (i.e., deposits of turbidity currents) were triggered by earthquakes. However, their conclusion falters because of (1) selective data sets that were used for establishing seismicity as the sole triggering mechanism of turbidites, (2) flawed sedimentological concepts and criteria that were applied for interpreting turbidites, and (3) faulty methodologies that were employed for correlating turbidites over long distances. This same turbidite (i.e., sedimentological) theme has also been published previously by Goldfinger et al. (2003a,b, 2006, 2007). As with the...
