THORSTEN W. BECKER Department of Earth Sciences University of Southern California Los Angeles Global tectonic maps

You can download a few files in gzipped Adobe Postscript (PS) or PDF (Acroread) format, the latter are typically smaller. All maps are meant to be printed on a standard 36" by 72" poster plotter (e.g. by sending the unzipped PS file straight to the printer). A legend in the lower right corner of these maps lists references and data sources. You can select from the following versions:

1. Topography, crustal velocities, Engdahl seismicity, and Harvard CMT solutions:
   

   [PS] [PDF] [PNG]	[PS] [PDF] [PNG]

   
   Download a gzipped PS file for a map centered on the Pacific or Africa; or a PDF of the same map with map center on the Pacific or Africa. (With illumination/shading: download a gzipped PS, or PDF, both are Pacific centered.)
2. Topography, plate motions, shallow (<50 km) seismicity and CMTs:
   

   [PS] [PDF] [PNG]	[PS] [PDF] [PNG]

   
   Download a gzipped PS file for a map centered on the Pacific or Africa; or a PDF of the same map with map center on the Pacific or Africa.
3. Topography, plate motions, seismicity:
   

   [PS] [PDF] [PNG]	[PS] [PDF] [PNG]

   
   Download a gzipped PS file centered on the Pacific or Africa; the corresponding PDF files, centered on the Pacific or Africa. (With illumination: gzipped PS or PDF , both Pacific centered.)

The iGMT produced GMT scripts used to make these maps can be found by following this link to the data ftp directory.

You might also want to check out a comparison of all the colormaps that come with GMT, as PDF files in their in their original spacing, or normalized to 0...1.
