The number of the death from the 7.0-magnitude earthquake that hit Ya’an in southwestern China's Sichuan Province has risen to 188, according to latest calculations by local Civil Affairs Bureau(as of 18:00 pm, April 22, ). At least 11,826 were reportedly injured in the quake while 25 are still missing.
