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. ↗

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. ↗

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. ↗

I suggested that we might compare earthquakes in terms of the measured amplitudes recorded at these stations, with an appropriate correction for distance. ↗

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. ↗

I was lucky because logarithmic plots are a device of the devil. ↗

I'm glad to see the press now referring to the open-ended Richter scale. ↗

If one introduces the concept of energy of an earthquake then that is a theoretically derived quantity. ↗

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. ↗

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. ↗
