This is very similar to astronomy where different magnitudes are assigned to the brightness of an astronomical object, depending on the range of wavelengths being measured. Charles Francis Richter assignastronomicalastronomy Change image and share on social
My amateur interest in astronomy brought out the term 'magnitude', which is used for the brightness of a star. Charles Francis Richter amateurastronomybrightness Change image and share on social
I suggested that we might compare earthquakes in terms of the measured amplitudes recorded at these stations, with an appropriate correction for distance. Charles Francis Richter amplitudecomparecorrection Change image and share on social
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. Charles Francis Richter amplificationbeliefcorrect share on social
