Where can I see current or past seismograms?
The USGS Earthquake Hazards Program has helicorders (seismogram displays) available for several areas in the United States and the World.
Our research partner IRIS (Incorporated Research Institutions for Seismology) has two applications, the Station Monitor and the Global Seismogram Viewer, for viewing seismograms. IRIS also supplies software that allows users to collect and view seismic data from around the world.
