Logarithmic plots are a device of the devil.
- Designation
- |
- Nov 07, 2020
Incidentally, the usual designation of the magnitude scale to my name does less than justice to the great part that Dr. Gutenberg played in extending the scale to apply to earthquakes in all parts of the world.

Refining is inevitable in science when you have made measurements of a phenomenon for a long period of time.
- Energy
- |
- Nov 07, 2020
If one introduces the concept of energy of an earthquake then that is a theoretically derived quantity.
- Development
- |
- Nov 07, 2020
Nothing is less predictable than the development of an active scientific field.

As seismologists gained more experience from earthquake records, it became obvious that the problem could not be reduced to a single peak acceleration. In fact, a full frequency of vibrations occurs.
- Differences
- |
- Nov 07, 2020
By moving them vertically, a representative mean curve could be formed, and individual events were then characterized by individual logarithmic differences from the standard curve.
- Gravity
- |
- Nov 07, 2020
Emphasis was usually put on the horizontal acceleration factor, for the simple reason that ordinary structures have a built-in safety factor for the vertical component; that is, gravity.
- Light

- Nov 07, 2020
For example, some stars put out large amounts of energy in the infrared part of the spectrum, so that this can produce a different relative magnitude rating than using light energy from the middle of the spectrum.

From here, it becomes an engineering problem; the engineer considers the ground motion that will occur and evaluates the requirements of the proposed structure in the light of the local foundation conditions.
- Amplification
- |
- Nov 07, 2020
I repeatedly have to correct this belief. In a sense, magnitude involves steps of 10 because every increase of one magnitude represents a tenfold amplification of the ground motion. But there is no 'scale of 10' in the sense of an upper limit.
- Correction
- |
- Nov 07, 2020
I suggested that we might compare earthquakes in terms of the measured amplitudes recorded at these stations, with an appropriate correction for distance.
- Life
- |
- Nov 07, 2020
I usually point out that most loss of life and property has been due to the collapse of antiquated and unsafe structures, mostly of brick and other masonry.
- Calculating
- |
- Nov 07, 2020
If the assumptions used in calculating energy are changed, then this seriously affects the final result, even though the same body of data might be used.
- Earthquake
- |
- Nov 07, 2020
In every area of the world where there is earthquake risk, there are still many buildings of this type; it is very frustrating to try to get rid of them.
- Fall
- |
- Nov 07, 2020
Intensity like signal strength will generally fall off with distance from the source, although it also depends on the local conditions and the pathway from the source to the point.
- Out

- Nov 07, 2020
My amateur interest in astronomy brought out the term 'magnitude', which is used for the brightness of a star.
- Ask
- |
- Nov 07, 2020
There is another common misapprehension that the magnitude scale is itself some kind of instrument or apparatus. Visitors will frequently ask to 'see the scale.'
