Slide presentation at the SAS conference, Philadelphia, June 2002
You
might ask..
How
in the World could amateurs add to the understanding of physical processes
involved in the preparation phase of earthquakes?
It
turns out, one of the more important discoveries in this regard was
made by an amateur scientist.
He traveled extensively, and always kept some of his favorite
instruments within easy reach.
He liked the barometer, and had a small pocket electrometer.
Once,
when traveling in Venezuela, he became curious about some strange
atmospheric events. He noted in his journal that he had observed electricity
in the air after seeing the pith balls of his pocket Volta electrometer
deflected from one another by four lines, often alternating between positive
and negative.
As one of the more powerful electric discharges was taking place, he
noted that two strong tremors struck.
The
amateur scientist was Alexander von Humboldt, and the year was 1799.
His careful observations of ocean currents off South America also
gained him some notoriety in that realm of science.
The Humboldt current was, of course, discovered by and named for
him.
So,
can amateur science contribute in any meaningful way to the study of
earthquake precursor phenomena?
Of course we can!
We can use our ingenuity to design and build instruments with
contemporary devices that run rings around those of Humboldt’s day.
