IRIS DMC Products and Education and Public Outreach
IRIS Education and Public Outreach and the University of Portland have established routine procedures to develop a set of “Teachable Moments” which provide a short summary of the latest major earthquake within a few hours to one day after an event. Prepared by seismologists and educators, “Teachable Moments” include powerpoint slides, .pdf presentations and animations.

Sonification of a seismogram from the North Korean explosion ¶
Video 1: SeisSound, the Audio/Video Seismic Waveform Visualization of the M5.1 North Korea's test (depth ~1 km) of February 12, 2013 seismogram recorded at station MDJ (at about 370 km from the test site). A 0.5 Hz high-pass filter is applied and a speed up factor of 500 is used to transform the seismogram frequencies to audible range. IRIS DMS Products.
Comparison with a natural earthquake ¶
Video 2: SeisSound, the Audio/Video Seismic Waveform Visualization of the M5.2 California-Nevada Border Region earthquake (depth 12 km) of February 13, 2013 seismogram recorded at station SAO (at about 330 km from the event, approximately the same distance as station MDJ from the North Korea's test). A 0.5 Hz high-pass filter is applied and a speed up factor of 500 is used to transform the seismogram frequencies to audible range. IRIS DMS Products.
