Different types of seismic waves travel at different speeds and through different parts of the Earth during a quake. The next set of seismic waves on your seismogram will be the S waves. During an earthquake, ground-shaking seismic waves radiate outward from the quake source, called the epicenter. You have probably heard of the Richter scale which is still used for small earthquakes, but most large earthquakes are now commonly reported using the moment magnitude scale (see below) . Scientists use seismographs that record the length and strength of each earthquake to try to determine if an eruption is imminent. Seismograph networks supply earthquake parameter and waveform data that are essential for the real-time evaluation of tectonic activity for public safety (e.g., volcanic eruptions, tsunamis, earthquake mainshocks and aftershocks), the development of earthquake hazard maps and seismic design criteria used in building codes and land-use planning .

This causes the waves to travel in curved paths. It also collects data from over 3,600 seismic intensity meters managed by local governments and the National Research Institute for Earth Science and Disaster Prevention (NIED). A network of worldwide seismographs detects and measures the strength and duration of the earthquake's waves. In addition, seismology helps to understand continental slopes that can also cause earthquakes. 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. The term seismograph usually refers to the combined seismometer and recording device. A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph".Seismographs are instruments used to record the motion of the ground during an earthquake. S-waves cannot travel through liquids or gases. P-waves are generally too subtle to be felt by humans Why are the properties of the asthenosphere important? . They only travel through solid material, and so are stopped at the liquid layer in the Earths core. Oceanic and continental plates are colliding. Seismographs can detect quakes that are too small for humans to feel. Why do scientists study seismographs? sudden movement along faults within the Earth Seismic phenomena are generally explained as the result of interactions and other processes at or near the edges of a few large mobile plates of lithosphere that spread apart at the ocean ridges where new surficial materials arise, slide past one another along the large strike-slip faults, and converge at the island . These three distances are then used to triangulate the epicenter. Unlike the seismograph, it lacks a device to calibrate the time. The slowest waves, surface waves, arrive last.
