Interactively plot volcano locations on a vivid topographic and bathymetric basemap to evaluate right-stepping offsets of the volcanic front of an active arc, Central America.
- Exploration of data
- Tool use (GeoMappApp)
- Recognition of volcanoes using GeoMapApp
- Identify patterns (what does the volcanic front look like?)
- Filtering of data using symbols, colors and changes in scale - deciding what data are critical to the question at hand

Teaching Notes and Tips
Problem 1: Can identify two or three right stepping offsets and realize that the raw topography works best, after using the vent data to learn to identify the volcanos.
Problem 2: Vent locations show no evidence of volcanic centers or clusters but the profile tool shows the centers quite well.
