Moment magnitude scale characterizing some classes of quakes. As a result, Beno Gutenberg expanded Richter's work to consider earthquakes detected at distant locations. For such large distances the higher frequency vibrations are attenuated and seismic surface waves (Rayleigh and Love waves) are dominated by waves with a period of 20 seconds, corresponding to a wavelength of about 60 km. Their magnitude was assigned a surface wave magnitude scale (). Gutenberg also combined compressional P-waves and the transverse S-waves (which he termed "body waves") to create a body-wave magnitude scale (), measured for periods between 1 and 10 seconds. Ultimately Gutenberg and Richter collaborated
Recomposed by Max Richter: Vivaldi – The Four Seasons Recomposed by Max Richter: Vivaldi – The Four Seasons Recomposed by Max Richter: Vivaldi – The Four Seasons is the 2012 album by neo-classical composer Max Richter, released on August 31, 2012 on Universal Classics and Jazz (Germany), a division of Universal Music Group, and Deutsche Grammophon. The album is a complete recomposition and reinterpretation of Vivaldi's "The Four Seasons". Although Richter said that he had discarded 75% of Vivaldi's original material, the parts he does use are phased and looped, emphasising his grounding in postmodern and minimalist music. The album was composed by Max Richter, played by the violinist
