A STUDY OF not so RECENT EARTHQUAKES.

A STUDY OF RECENT EARTHQUAKES.


CHAPTER I.

INTRODUCTION.

I propose in this book to describe a few of the more important
earthquakes that have occurred during the last half century.

In judging of importance, the standard which I have adopted is not
that of intensity only, but rather of the scientific value of the
results that have been achieved by the study of the shocks.

Even with this reservation, the number of earthquakes that might be
included is considerable; and I have therefore selected those which
seem to illustrate best the different methods of investigation
employed by seismologists, or which are of special interest owing to
the unusual
character of their phenomena or to the light cast by them on the
nature and origin of earthquakes in general.

Thus, the Neapolitan earthquake possesses interest from a historical
point of view; it is the first earthquake in the study of which modern
scientific methods were employed.

The Ischian earthquakes are described as examples of those connected
with volcanic action; the
Andalusian earthquake is chiefly remarkable for the recognition of the
unfelt earth-waves; that of Charleston for the detection of the double
epicentre and the calculation of the velocity with which the
vibrations travelled.

In the Riviera earthquake are combined the principal features of the
last two shocks with several phenomena of miscellaneous interest,
especially those connected with its submarine foci.

The Japanese earthquake is distinguished from others by its
extraordinary fault-scarp and the very numerous shocks that followed
it.

The Hereford earthquake is a typical example of a twin earthquake, and
provided many observations on the sound phenomena; while the Inverness
earthquakes are important on account of their connection with the
growth of a well-known fault.

The great Indian earthquake owns few, if any, rivals within historical
times, whether we consider the intensity of the disturbance or the
diversity and interest of the phenomena displayed by it--the
widespread changes in the earth's crust, both superficial and deep-
seated, and the tracking of the
unfelt pulsations completely round the globe.

Loads of stuff on there. Pity the paragraph spacings are not ideal.
