Seismic magnitude scales Seismic magnitude scales Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location. Magnitudes are usually determined from measurements of an earthquake's seismic waves as recorded on a seismogram. Magnitude scales vary on the type and component of the seismic waves measured and the calculations used. Different magnitude scales are necessary because of differences in earthquakes, and in the purposes for which magnitudes are used. The Earth's crust is stressed
Boomerang effect (psychology) such a claim followed by a correction. They found that the corrections frequently fail to reduce misconceptions for the ideological group targeted by the misinformation. They also found cases of what they called a "backfire effect" (i.e. a boomerang effect) in which the corrections strengthened belief in the misinformation.
