Mencius's definition of human nature (xing) differed from that of the Greek philosophers, such as Aristotle and Plato.

1964 Alaska earthquake. The 1964 Alaskan earthquake, also known as the Great Alaskan earthquake and Good Friday earthquake, occurred at 5:36 PM AST on Good Friday, March 27. Across south-central Alaska, ground fissures, collapsing structures, and tsunamis resulting from the earthquake caused about 139 deaths. Lasting four minutes and thirty-eight seconds, the magnitude 9.2 megathrust earthquake was the most powerful recorded in North American history, and the second most powerful recorded in world history. 600 miles of
Alaska is one of the world's most seismically active areas. 11% of the world's earthquakes occur in Alaska, and three of the 10 largest earthquakes ever recorded in world history were in Alaska. The only reason that the total death toll for the Good Friday Earthquake didn't even come close to the large December 26, 2004 Asia 9.0 earthquake is because Alaska is so sparsely populated. Alaska's population has grown greatly since 1964, so if the same quake was to happen again, the death toll would easily be much higher.
