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.

[In plotting earthquake measurements] the range between the largest and smallest magnitudes seemed unmanageably large. Dr. Beno Gutenberg then made the natural suggestion to plot the amplitudes logarithmically.

My main point today is that usually one gets what one expects, but very rarely in the way one expected it.

Refining is inevitable in science when you have made measurements of a phenomenon for a long period of time.

Don't wait for extraordinary circumstance to do good; try to use ordinary situations.

Spring makes everything young again except man.

Only fools, liars, and charlatans predict earthquakes
