jAmaSeis facilitates the study of seismological concepts in middle school through introductory undergraduate classrooms.

Users can also filter data, fit a seismogram to travel time curves, triangulate event epicenters on a globe, estimate event magnitudes, and generate images showing seismograms and corresponding calculations.
