Figure 8
From: Lateral Variation of Crustal Lg Attenuation in Eastern North America
On the upper left plot, an average Q Lg (1.0–10.0 Hz) map is presented showing location of three lines associated to each subplots ((I), (II), and (III)). In each subplot, from top to bottom: (a) Surface topography, (b) Moho depth based on CRUST1.083 with seismicity, (c) Q Lg versus frequency, and (d) average Q Lg . The horizontal coordinate is longitude. The figure is generated from GMT, which is an open source software available at: http://gmt.soest.hawaaii.edu.
