Event Plots
IRIS EventPlots Body wave record sections are ‘combed’ to show the most even distribution of stations that meet a minimum signal to noise ratio criteria.

Back Projection
IRIS BackProjection The Back Projection (BP) product shows the beam formed time history and location of coherent short period P-wave energy generated by large earthquakes observed at three regional arrays and across the Global Seismic Network.

IRIS Aftershocks The Aftershocks product consists of an aftershock sequence animation, a map and other figures automatically generated for all events with magnitudes 7.0 and greater.

Surface-Wave Radiation Pattern
IRIS SWRP The Surface-Wave Radiation Pattern product shows the patterns of seismic energy radiation by azimuth around the epicenter for Rayleigh and Love waves.
