We are pleased to announce that our app Earthtunes has been submitted to the Apple Store. Earthtunes helps you listen to the solid Earth on your iphone or ipad. Solid-Earth ground motions are continuously recorded by sensitive seismic stations for research and monitoring purposes, and now, with Earthtunes, can be easily listened to. You will find that few days sound the same as other days and each place has characteristic sounds you don’t hear everywhere. Please check the App Store for Earthtunes after Dec 22, download Earthtunes for free, have fun with it, and send us feedback on this web site.
