Audification of a ML=4.2 earthquake in Hungary

For more info see the EMSC report.

Click the speaker symbols in the map to hear the earthquakes. Please turn your volume down a little bit when playing the sound for the first time.
The seismograms have been audified by speeding up the seismograms by a factor of 440. This means, a frequency of 1Hz in the seismogram will sound at 440Hz.
You can clearly hear how the waveform changes when the epicentral distance grows. The stations near the epicenter are sharp and somehow sound like a hit on a metal ton. At stations farther away one already can hear the splitting of the P and S waves creating some kind of echo like effect. Moreover it's clear to hear how the event amplitude decreases resulting in a higher noise level before and after the earthquake signal. Listening to the sound examples also makes clear why seismic noise is named seismic noise .

Below the audio map, you can find the seismo- and spectrograms of the according stations.
