This talk will focus on a comparison of two somewhat related volcanic arcs: the Central American Volcanic Arc and the Cascades Volcanic Arc. These two arcs both originated from the Farallon Plate but they differ in terms of their subduction rate, angle of subduction, and distance from their respective spreading centers. These differences seems to have resulted in different rates of volcanic production -- or are these production rates all that different after all? Join Bill Burgel for a look at the similarities and differences between these two volcanic arcs.
