Els Sismògrafs de l'Observatoria de Cartuja (Granada) : recuperació del «Macrosismògraf Cartuja» Authors Josep Batlló Ortiz Carme Clemente Delgado Francisco Pérez-Blanco José Morales Abstract The Cartuja observatory, in Granada, was founded by the Society of Jesus in 1902. Soon it was widespread known for its research in seismology. Special attention should be drawn to the different seismographs designed and built at the centre. This task spread for forty years and more than twenty different models arose from its workshop. They covered all faces of seismic recording: from big earthquakes to ambient noise and industrial vibrations and even pedagogical instruments. Cartuja observatory was the most important institute in Spain dealing with seismograph design and one of the leading centres in Europe. Its designs spread to different seismic observatories in Central and South America and to Italy. Almost all the instruments designed and built at the centre have been lost. But, recently, what is remaining of the last built seismograph in year 1949, the «Cartuja macroseismograph», was found. This instrument has been restored at the restoration workshop of the Tortosa School of Art and Design. Priority in the restoration has been given to didactical insight and some parts of the instrument have been built a new to allow a good understanding of how it was operated. Present work analyzes the importance of the seismographs built at the Cartuja Observatory, its influence in the development of the instrumental seismology and shows the results of the restoration of the «Cartuja macroseimograph».
