Auditory seismology on free oscillations, focal mechanisms, explosions and synthetic seismograms
MetadataShow full item record
The method of audifying seismograms and interpreting seismological data by ear enables a wide range of geophysical questions to be studied in a new manner. In this article we report about the actual state of research in Auditory Seismology. Some tests were carried out in the area of free oscillation phenomena, focal mechanisms of earthquakes, explosion signals and synthetic seismograms. The results confirm the difference between visual and acoustic approach as having different foci: Free oscillations as a phenomenon of resonance are easily accessible for the ear, whereas synthetic seismograms give acoustically less insight than visually. Beyond the seismological investigation the article gives a historical introduction of Auditory Seismology up to the present, and a summary of earlier results to contextualize these and assist the process of establishing the acoustical approach as an individual research field.
