Jan 1, 2021 · Seismogram interpretation, described in this article, is essentially devoted to the art of identification of various seismic “arrivals” or wave types visible on seismograms.
A seismogram is the recording of the ground shaking at the specific location of the instrument. On a seismogram, the HORIZONTAL axis = time (measured in seconds) and the VERTICAL axis= ground displacement (usually measured in millimeters).
A seismogram is the recording of earth displacement as a function of advancing time. The recording may be made on photosensitive paper by a moving beam of light that requires darkroom seismic vaults, or on wax-coated paper by a heated stylus, or on ordinary paper by pen and ink.
Jan 1, 1995 · Travel-time curves are a primary tool for interpreting a seismogram and identifying phases. If the location of the source is not independently known, the usual procedure is first to determine an approximate epicentral distance.
Jan 1, 2002 · Introduction. Interpretation of seismograms is devoted to the art of identification of various types of seismic waves (phases) that appear on seismograms and often generate a rather complex structure.
Ever wondered how to read the data on a seismogram? This playful animation created for the general public by the USGS describes what a seismogram is, how they are recorded and what to look for in the seismic traces recorded on a seismometer.
