Tokyo Magnitude 8.0 reach her own daughter and mother in Sangenjaya. Together, the three of them brave the partly ruined city and try their best to make it home safely. The series was first announced at the 2009 Tokyo Anime Fair, denoting that it would replace "Eden of the East" in Fuji TV's noitamina well-rated anime timeblock and would be co-produced by Bones and Kinema Citrus. The series' setting is based upon the prediction that there is 70% or higher chance of an earthquake measuring 7.0 magnitude on the Richter scale hitting Tokyo in the next 30 years, with the series illustrating the
Absolute magnitude and a difference of n magnitudes in absolute magnitude corresponds to a luminosity ratio of 100. For example, a star of absolute magnitude M=3 would be 100 times more luminous than a star of absolute magnitude M=8 as measured in the V filter band. The Sun has absolute magnitude M=+4.83. Highly luminous objects can have negative absolute magnitudes: for example, the Milky Way galaxy has an absolute B magnitude of about −20.8. An object's absolute bolometric magnitude represents its total luminosity over all wavelengths, rather than in a single filter band, as expressed on a logarithmic magnitude scale. To convert
