Study Area Locations (IMAGE) Geological Society of America Caption Figure 1. A: Map of the western North Pacific showing study area with locations of Lake Daija (circle), Kamikoshiki (triangle), and site of Mongol wreckage in Imari Bay (square), Japan. Paths of best track category 3 and greater typhoons passing within 90 km of Lake Daija (solid lines) and the most intense best track typhoon to impact Imari Bay (a weak category 2 typhoon in 1985 CE, dashed line) are noted. Path of the 1281 CE typhoon (dot-dash) is based on Turnbull (2010), and has been extended south of Imari Bay with a trajectory similar to that of the 1985 CE typhoon. B: Satellite image of Lake Daija with superimposed bathymetry and core locations (circles). Star indicates location where photo in C was taken. C: Photo of Lake Daija with position of cores. Core positions in sequential order from 1 to 4 are 32.2475°N, 129.98601°E; 32.2472 °N, 129.98576°E; 32.24699°N, 129.98557°E; and 32.24792°N, 129.98666°E.
