Listen to Earthquakes
I’ve been working on a set of scripts that will play sped-up seismograms as sound. I was very proud of myself last night for remembering enough Perl to translate from one format to another, thereby producing clicking noises. Obviously I’m still doing something wrong in the processing necessary to translate from a 10 minute seismogram, recorded at 50 samples/sec to catch interesting stuff that happens at frequencies well below the range of human hearing, to a 5 second audio clip played back at ten thousand or so samples/sec… but hey, clicking noises are better than nothing!
Then I found that someone has set up a blog of “soundquakes”, which automagically generates an entry containing maps, seismograms, and sound files for every M>5 earthquake that occurs anywhere in the world. Très cool. And, way to make me feel inadequate, anonymous Internet gnomes!
