Students learn the two main methods to measure earthquakes, the Richter Scale and the Mercalli Scale. Students are challenged by the associated activities to make a model of a seismograph—a measuring device that records an earthquake on a seismogram. As well as to investigate which structural designs are most likely to survive an earthquake. And, they illustrate an informational guide to the ...
In 1979, as geologists developed more accurate techniques for measuring energy release, a new scale replaced the Richter: the moment magnitude, or MW scale, which seeks to measure the energy released by the earthquake. It’s also a logarithmic scale and comparable to Richter for small and medium quakes—a 5.0 on the Richter scale, for example ...

Apr 24, 2024 · Earthquake magnitudes are determined by measuring the amplitudes of seismic waves. The amplitude is the height of the wave relative to the baseline (Figure 12.15). Wave amplitude depends on the amount of energy carried by the wave. The amplitudes of seismic waves reflect the amount of energy released by earthquakes.
There are many different ways to measure different aspects of an earthquake: Magnitude is the most common measure of an earthquake's size. It is a measure of the size of the earthquake source and is the same number no matter where you are or what the shaking feels like.

Apr 24, 2024 · Figure 11.3.1 11.3. 1 image description: P-waves and S-waves from a small (M4) earthquake near Vancouver Island in 1997. The P-wave arrived in 0.7 seconds with an amplitude ranging from negative 0.7 millimeters per second to 1.1 millimeters per second and lasting until the arrival of the S-wave.
