THE INTERNATIONAL SCIENTIFIC SERIES
VOLUME LV
In the following pages it has been my object to give a systematic account of various Earth Movements.
These comprise Earthquakes, or the sudden violent movements of the ground; Earth Tremors, or minute movements which escape our attention by the smallness of their amplitude; Earth Pulsations, or movements which are overlooked on account of the length of their period; and lastly, Earth Oscillations, or movements of long period and large amplitude which attract so much attention from their geological importance.
It is difficult to separate these Earth Movements from each other, because they are phenomena which only differ in degree, and which are intimately associated in their occurrence and in their origin.
Contents
Introduction -- Seismometry -- Earthquake motion discussed theoretically -- Earthquake motion as deduced from experiment -- Earthquake motion as deduced from observation on earthquakes -- Effects produced by earthquakes upon buildings -- Effects produced upon buildings (continued) -- Effects of earthquakes on land -- Disturbances in the ocean -- Determination of earthquake origins -- The depth of an earthquake centrum -- Distribution of earthquakes in space and time -- Distribution of earthquakes in time (continued) -- Distribution of earthquakes in time (continued) -- Barometrical fluctuations and earthquakes; fluctuations in temperature and earthquakes -- Relation of seismic to volcanic phenomena -- The cause of earthquakes -- Prediction of earthquakes -- Earth tremors -- Earth pulsations -- Earth oscillations -- Appendix: List of the principal books, papers, periodicals, which are referred to in the preceding pages.
