A government task force focused on earthquake research intends to redesign its hazard maps to make it easier for those with color vision deficiencies to identify risks, an official said Wednesday.

The move is part of an effort by the government body to comprehensively revamp the maps, which use various colors to indicate the extent to which each area across the nation is susceptible to quakes, said Masahiro Nakade, an official at the Headquarters for Earthquake Research Promotion.

The redesigned maps will employ nine colors to signify the degree of danger facing each area, from the most urgent red-violet to the safest light gray.
