The observation of earthquakes: A guide for the general observer

Abstract

This article is designed to put before the public in systematic, readable form such information about earthquakes as will enable ordinary observers to co-operate effectively with specially trained investigators in carrying through extensive earthquake surveys and inquiries. It is hoped that it will stimulate the widespread making of records of the behavior of earthquakes, especially throughout California and the neighboring region. It may be regarded simply as a brief manual for volunteer observers.
