Work in progress from 422 South data visualization artist Jim Walters – this sequence shows all the earthquakes in the region of Tōhoku Japan during 2011 – Including a magnitude 9.0 (Mw) undersea megathrust earthquake that occurred at 05:46 UTC on Friday 11 March, with an epicentre approximately 70 kilometres east of the Oshika Peninsula at an underwater depth of approximately 30 km. It was the most powerful earthquake ever recorded to have hit Japan, and the fourth most powerful earthquake in the world since modern record-keeping began in 1900. The quake and subsequent tsunami caused the deaths of 15,893 people.
Both sound and vision are driven by the raw data, which shows quakes of magnitude 4 or greater. The louder the audio and brighter the dot – the bigger the quake. Jim plans to further refine the piece with variable size dots, the addition of a date counter and higher levels of realism in the earth model.
