Its the fastest kind of seismic wave, and the first to arrive at a seismic station. Think of a solid material, like a rock. When P-waves strike the outer core, however, they bend downward when traveling through the outer core and bend again when they leave. The next set of seismic waves on your seismogram will be the S waves. To monitor earthquakes, JMA operates an earthquake observation network comprised of about 200 seismographs and 600 seismic intensity meters. This cookie is set by GDPR Cookie Consent plugin. .

The velocity of s waves going through the asthenosphere decreases, which tells us that peridotite contains a few percent partial melt, but not enough to stop s waves. There are instruments throughout the world that detect earthquakes called seismometers and seismographs. Often, several slightly different magnitudes are reported for an earthquake. These measurements allow scientists to estimate the distance, direction, magnitude, and the type of earthquake that just occurred.

They can still propagate through the solid inner core: when a P wave strikes the boundary of molten and solid cores at an oblique angle, S waves will form and propagate in the solid medium. Seismographs are equipped with electromagnetic sensors that translate ground motions into electrical changes, which are processed and recorded by the instruments' analog or digital circuits.
