Rudolf Falb

Rudolf Falb (14 April 1838, Obdach (Styria, Austrian Empire – 29 September 1903, Schöneberg, German Empire) was an Austrian popularizer of natural history who concerned himself with earthquakes, meteorology, astronomy and also with evolutionary linguistics. He developed the lunisolar flood hypothesis of earthquakes and volcanism, based on the concept of subterranean lava tides, which the academic community thoroughly refuted even during his lifetime; nevertheless he attained considerable popularity through apparently correct predictions of several seismic events and through numerous failed predictions including the end of the world through the collision of Biela's Comet. Falb's lasting legacy is that he popularized the concept of extraterrestrial influences of geophysical phenomena, even though his concepts regarding the origins of earthquakes were wrong.
