—Electric fluids are,doubtlessly, the cause of the slight and
perfectly harmlesstrembling of the earth’s surface, which has often
continuedfor several days (as in 1816, at Scaccia, in Sicily, before
thevolcanic elevation of the island of Julia), as well as of
theterrific explosions, accompanied by loud noise. The focus ofthis
destructive agent, the seat of the moving force, lies farbelow the
earth’s surface; but we know as little of the extentof this depth as
we know of the chemical nature of thesevapours that are so highly
compressed. At the edges of twocraters, Vesuvius and the towering rock
which projects beyondthe great abyss of Pichincha, near Quito, I have felt
periodicand very regular shocks of earthquakes, on each occasionfrom
twenty to thirty seconds before the burning scoriæ orgases were
erupted. The intensity of the shocks were in-creased in proportion to the
time intervening between them,and, consequently, to the length of time in
which the vapourswere accumulating. This simple fact, which has been
attestedby the evidence of so many travellers, furnishes us with
ageneral solution of the phenomenon, in showing that activevolcanoes
are to be considered as safety-valves for the imme-diate neighbourhood. The
danger of earthquakes increaseswhen the openings of the volcano are closed
and deprived offree communication with the atmosphere; but the
destructionof Lisbon, of Caracas, of Lima, of Cashmir in 1854, and of
somany cities of Calabria, Syria, and Asia Minor, shows us, onthe
whole, that the force of the shock is not the greatest inthe neighbourhood
of active volcanoes.—Humboldt’s Cosmos.
Volcanoes are Safety-valves.
