WebEarthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs. (The types and nature of these waves are described in the section Seismic waves.) Because the size of earthquakes varies enormously, it is necessary for purposes of comparison to compress the range of … WebJul 22, 2024 · When the Earth trembles, earthquakes spread energy in the form of seismic waves. A seismograph is the primary earthquake measuring instrument.

"WebP waves are also known as compressional waves, because they push and pull. Particles subjected to a P wave move in the same direction that the wave is moves in; it is the direction that the energy is traveling in, sometimes called the “direction of wave propagation.”. A P wave travels through a medium by means of compression and dilatation. " - How do we measure seismic waves

WebSeismic waves from large earthquakes are detected around the world using seismometers. Their paths are usually curved – this is due to the fact that the waves are refracted as they meet the... WebMar 31, 2024 · Since modern seismographs can detect seismic waves even smaller than those originally chosen for zero magnitude, it is possible to measure earthquakes having negative magnitudes on the Richter scale. Each increase of one unit on the scale represents a 10-fold increase in the magnitude of an earthquake.
