FA Reuss

FA Reuss publishes "Geography of the North Bohemian Mountains" with the question: "Is basalt volcanic or not?" The idea that volcanic activity could be caused by the burning of massive coal seams was widely debated at the time. The burning of fossil coal seams was a well-known and dangerous phenomenon in North Bohemia. However, later calculations showed that the energy required for volcanic activity is several orders of magnitude greater and cannot be released by burning coal.
