Developed by Caltech's Hiroo Kanamori and seismologist Thomas C. Hanks, this is the only method of measuring magnitude that is uniformly applicable to all sizes of earthquakes, but it is more difficult to ...Measuring Earthquakes. The vibrations produced by earthquakes are detected, recorded, and measured by instruments call seismographs. The zig-zag line made by a seismograph, called a "seismogram," reflects the changing intensity of the vibrations by responding to the motion of the ground surface beneath the instrument.Nepal Earthquake 2015. Eyjafjallajokull Case Study. Christchurch Earthquake Case Study. Haiti Earthquake 2010. The Holderness Coast Case Study.In an earthquake, huge masses of rock move beneath the Earth ’s surface and cause the ground to shake. Earthquakes occur constantly around the world. Often they are too small for people to feel at all. Sometimes, however, earthquakes cause great losses of life and property.

How Do We Measure Earthquakes? The energy from an earthquake travels through Earth in vibrations called seismic waves. Scientists can measure these seismic waves on instruments called seismometer. A seismometer detects seismic waves below the instrument and records them as a series of zig-zags.

Earthquake - Magnitude, Seismology, Epicenter: Earthquake magnitude is a measure of the "size," or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs. (The types and nature of these waves are described in the section Seismic waves.)

No matter what scale is used, quakes are detected using devices called seismographs, which measure ground motion and produce images showing how these vibrations travel over time. The magnitude of …TREMORS FROM BELOW. Earthquakes are happening all the time. Most are so small that people don’t even feel them. But some can be very powerful. If they occur near towns and cities, they can make buildings and bridges sway or even collapse. Earthquakes can also occur along the seafloor and cause it to move. Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept.
