Measure seismic waves

A seismometer is an instrument that detects seismic waves. An instrument that combines a seismometer with a device for recording the waves is called a seismograph. The graphical output from a seismograph is called a seismogram. Figure 12.10 (right) shows how a seismograph works. The … See more P-waves travel faster than S-waves. As the waves travel away from the location of an earthquake, the P-wave gets farther and farther ahead of the S-wave. Therefore, the farther a seismograph … See more Earthquakes can be described in terms of their magnitude, which reflects the amount of energy released by the shaking. They can also be described … See more WebStudents examine seismic evidence to determine that the Earth must have a layered internal structure and to estimate the size of Earth's core. Using an inquiry approach, students are divided into two teams (theoreticians and seismologists) to test the simplest hypothesis for what is inside of Earth; that the Earth is homogeneous throughout.

WebIt is seismic waves from an earthquake or other natural events that a seismograph picks up. There are two main types of waves: body waves, which can travel through the inner layers of the earth, and surface waves, which can only travel on the surface. Body waves are the fastest and have the highest frequency. WebThese seismic waves are divided into two categories: body waves and surface waves. ... The magnitude scale is an important tool for scientists to understand and measure the energy released by an earthquake. It is a logarithmic scale, meaning that each magnitude increase corresponds to a tenfold increase in energy. This is why an earthquake with ...

WebSeismometers are instruments designed to be sensitive enough to feel even the smallest motion of the waves coming from distant locations on Earth. By understanding how seismic waves travel these records of ground motion, called seismograms, can be interpreted to enable us to locate the earthquake’s source.
