Abstract
In this chapter, I introduce a novel approach addressed to education in geosciences. It is based on application of sonification techniques, combined with hypermedia and quick response (QR) code technology. Sonification is a set of techniques aimed at conveying information by using nonspeech sounds. Hypermedia is a generalization of multimedia characterized by user interactivity and hyperlinks. QR code is a machine-readable optical label consisting of black modules, commonly arranged in a square grid on a white background. It allows fast information readability and immediate item identification. The method discussed in this chapter starts with converting geophysical data into sounds through application of accurate time-to-frequency transforms. Images and sounds derived from the same geophysical information are corendered in visual–audio displays and into highly informative videos. These are linked on the web by QR codes. Using this approach, I show how hypermedia geophysical files can be created and shared on the web, with the following main goals: (1) combining heterogeneous data; (2) improving data analysis and interpretation; (3) allowing quick information retrieval; and (4) improving education and communication. I discuss an application of this approach for describing the volcanic eruption of Mt. St. Helens happened in 1980 through an inedited combination of media.
