IRIS EMC — Horizontal Slice Viewer 
Version 2.0

In version 2.0 ALL Earth model variables, contained in the netCDF model file, are available for plotting.

The Horizontal Slice Viewer plots a depth slice from a selected Earth model. The quantity displayed depends on the selected model variable.

Users have the option of adding the following auxiliary data to the map by checking the corresponding menu box:
    N largest events ("N" defined by user) from the IRIS database (service.iris.edu/fdsnws/event/1/).
   events are from depths between the selected depth and halfway to the next depth above and below.
    N largest global CMT solutions ("N" defined by user) from the IRIS database (www.iris.edu/spud/momenttensor).
   events are from depths between the selected depth and halfway to the next depth above and below.
   shear-wave splitting from the G√©osciences Montpellier SplitLab shear-wave splitting database (www.iris.edu/dms/products/sws-db/)
   Slab1.0, a three-dimensional compilation of global subduction geometries, separated into regional models for each major subduction zone.
  Hayes, G. P., D. J. Wald, and R. L. Johnson (2012), Slab1.0:A three-dimensional model of global subduction zone geometries,
      J. Geophys. Res., 117, B01302, doi:10.1029/2011JB008524.

   The contours, if present, represent depth to slab at 20 km increments (earthquake.usgs.gov/research/data/slab)
   plate boundaries based on the information available from www.ig.utexas.edu/research/projects/plates
   volcano locations based on www.ngdc.noaa.gov/hazard

Notes
   • Use the companion interactive Google Map to select the region of interest and also see the extent of the selected model.
   • There is a known issue with the geographic boxes that cross the prime meridian!
   • You may further refine the plot on your own computer by downloading the associated Generic Mapping Tools (GMT) bundle
      (the bundle download link appears under the image once the processing is complete).
   • The generated images will be removed after 7 days
   • On the map the area covered by the selected model is shown in
green
   • Move the map markers to set the corresponding latitude and longitude values
