Here are all the built-in scales in the plotly.colors.sequential module: import plotly.express as px fig = px.colors.sequential.swatches_continuous() fig.show() Note: RdBu was included in the sequential module by mistake, even though it is a diverging color scale. It is intentionally left in for backwards-compatibility reasons.This scale is open-ended i.e. there is not any end of the scale but, it has never measured any Earthquake of magnitude greater than 8.9. The Richter-scale, in nature, is logarithmic based on 10. That is, the Earthquake at magnitude 5 is 10 times more powerful than the Earthquake at magnitude 4 and 100 times more than the earthquake at magnitude 3.So, for example, a magnitude 2 earthquake is 31 times more powerful than a magnitude 1 earthquake. The moment magnitude scale is often referred to by the name of its predecessor, the Richter Scale. Measurements on the Modified Mercalli Intensity (MMI) scale range from I to XII and are based solely on damage assessment and eyewitness accounts. 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.

Detailed Description. Although numerous intensity scales have been developed over the last several hundred years to evaluate the effects of earthquakes, the one currently used in the United States is the Modified Mercalli Intensity (MMI) Scale. It was developed in 1931 by the American seismologists Harry Wood and Frank Neumann.The range of intensity is from 1-12. Also read: Avalanche: Types, Causes and Mitigation. Richter Scale. The scale represents the magnitude of the earthquake. The magnitude is expressed in absolute numbers from 1-10. Each whole number increase in the Richter scale represents a tenfold increase in the power of an earthquake.

Magnitude. A familiar analogy to help understand earthquake size metrics is to think about a light bulb. One measure of the strength of a light bulb is how much energy it uses. A 100-watt bulb is brighter than a 50-watt bulb, but not nearly as bright as a 250-watt bulb. The wattage of a bulb tells you about the strength of the light source.

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.)

Great earthquakes, such as the 1964 Good Friday earthquake in Alaska, have magnitudes of 8.0 or higher. Although the Richter Scale has no upper limit, the largest known shocks have had magnitudes in the 8.8 to 8.9 range. Recently, another scale called the moment magnitude scale has been devised for more precise study of great earthquakes.

So, for example, a magnitude 2 earthquake is 31 times more powerful than a magnitude 1 earthquake. The moment magnitude scale is often referred to by the name of its predecessor, the Richter Scale. Measurements on the Modified Mercalli Intensity (MMI) scale range from I to XII and are based solely on damage assessment and eyewitness accounts.Real-time Seismogram Displays.
