Earthquake duration magnitude (Md) for earthquakes recorded on short-period vertical seismographs. Numerous studies determined the relation between coda duration and magnitude for different regions of the World. According to a recent study by Mandal et al. (2004), previous studies showed that duration magnitude estimation is quite stable for local earthquakes ranging from magnitude Md 0.0 to 5.0. In two most recent investigations using statistically stable samples for Italian earthquakes [approximately 100,000 events over the period 1981-2002 in the Richter local [ML] magnitude range of 3.5-5.8] and for Indian earthquakes exemplified by an aftershock sequence of 121 events with (surface wave magnitude) > 4.0
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
