Seismic magnitude scales are the most destructive. Deeper earthquakes, having less interaction with the surface, produce weaker surface waves. The surface-wave magnitude scale, variously denoted as Ms, M, and M, is based on a procedure developed by Beno Gutenberg in 1942 for measuring shallow earthquakes stronger or more distant than Richter's original scale could handle. Notably, it measured the amplitude of surface waves (which generally produce the largest amplitudes) for a period of "about 20 seconds". The scale approximately agrees with at ~6, then diverges by as much as half a magnitude. A revision by , sometimes labeled M, measures only waves of
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
