How Do I Read a Seismogram? When you look at a seismogram, there will be wiggly lines all across it. These are all the seismic waves that the seismograph has recorded. Most of these waves were so small that nobody felt them. These tiny microseisms can be caused by heavy traffic near the seismograph, waves hitting a beach, the wind, and any ...

Seismograms: Illustrated Guide to Reading a Seismogram (USGS) 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.

How Do You Read a Seismograph? Home Science Earth Science Earthquakes. How Do You Read a Seismograph? A seismogram is interpreted when geologists look at squiggly lines made by a seismograph on a piece of paper, according to Michigan Technological University. Initial waves, called P waves, are small and close together because they travel quickly.

The seismograms show a record of how the ground moved at a particular seismograph station during a 24-hour period. The seismogram is “read” like a book, from left to right and top to bottom (this is the direction that time increases). As with a book, the right end of any horizontal line “connects” with the left end of the line below it.

considerable training to be able to read seimograms. Figure 1— A seismograph has 3 sensors that record N–S, E–W, and vertical motion on 3 seismograms. The different behavior of P, S, and surface waves explain how a single seismograph station can have 3 different seismograms: 1) The vertical component shows the compressive P wave bumping up
