Contributions to plate tectonic theory and/or geophysics

On November 1, 1900, Bernard Brunhes took an appointment as the Director of the Observatory of the Puy de Dome.  The Puy de Dome Observatory was established in 1876 as a meteorological observatory and continues its operations today.  https://icos-atc.lsce.ipsl.fr/puy-de-dome-observatory  While serving as director, Brunhes took the opportunity to expand upon the work of Giuseppe Folgheraiter.  In 1894, Folgheraiter released his study showing the alignment of magnetic fields in baked pottery and bricks.  Brunhes used this knowledge of magnetic alignment as he studied the clays that were baked during lava flows in the surrounding areas.  He sampled the clays from Beaumont (the Montijoli volcano), village of Boissejour (the Gravenoire volcano), and at Pontfarein.
