Humboldt, Alexander von, 1769-1859

"COSMOS: A Sketch of the Physical Description of the Universe, Vol. 1"

Daubeney 'On Volcanoes', p. 514-517.] -- Tr.

Remote springs were interrupted in their flow, a phenomenon attending
earthquakes which had been noticed among the ancients by Demetrius the
Callatian. The hot springs of Toplitz dried up, and returned, inundating
every thing around, and having their waters colored with iron ocher. In
Cadiz
p 211
the sea rose to an elevation of sixty-four feet, while in the Antilles,
where the tide usually rises only from twenty-six to twenty-eight inches, it
suddenly rose above twenty feet, the water being of an inky blackness. It
has been computed that on the 1st of November, 1755, a portion of the
Earth's surface four times greater than that of Europe, was simultaneously
shaken. As yet there is no manifestation of force known to us, including
even the murderous inventions of our own race, by which a greater number of
people have been killed in the short space of a few minutes: sixty thousand
were destroyed in Sicily in 1693, from thirty to forty thousand in the
earthquake of Riobamba in 1797, and probably five times as many in Asia
Minor and Syria, under Tiberius and Justinian the elder, about the years 19
and 526.
There are instances in which the earth has been shaken for many successive
days in the chain of the Andes in South America, but I am only acquainted
with the following cases in which shocks that have been felt almost every
hour for months together have occurred far from any volcano, as, for
instance, on the eastern declivity of the Alpine chain of Mount Cenis, at
Fenestrelles and Pignerol, from April, 1808; between New Madrid and Little
Prairie,* north of Cincinnati in the United States of America, in December,
1811, as well as through the whole winter of 1812; and in the Pachalik of
Aleppo, in the months of August and September, 1822.
