Earthquake Magnitude Comparison Calculator .
It can be derived from the logarithm of the maximum displacement or amplitude of the earthquake. It is a logarithmic scale, meaning that the numbers on the scale measure factors of 10. A measurement scale used to measure the earthquake magnitude is the Richter Scale, which was developed by the seismologists Charles Francis Richter … Each square will represent 0.5 units. Your scale should start at 1 and end on the right at 9.
Each square will represent 20 mm.
The magnitude is the quantified measure of the earthquake size and is measured using a seismometer. Graph the data …
Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept.
So, for example, an earthquake that measures 4.0 on the Richter scale is 10 times larger than one that measures 3.0. Charles Richter developed the Richter Scale in 1935.His scale was based on the seismogram measured by a particular type of seismometer at a distance of 100 kilometres (62 mi) from the earthquake.. Earthquakes 4.5 or higher on the Richter scale can be measured by tools all over the world. The graph to the left gives a visual representation of what the Richter Scale presents.
The Richter scale is a standard scale used to compare earthquakes. The Richter magnitude scale is a scale of numbers used to tell the size of earthquakes. Your y-axis scale should start at 0 mm and go up to 400 mm.
It shows the magnitude numbers on the left and the energy released by the earthquakes on the right.
Next in the graph there is examples of earthquakes and what the energy given off is equivalent to.
The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations.
