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
(CNN)-- Alaskans were shaken up -- but not, it seems, rattled -- by a 6.2-magnitude earthquake and more than a dozen aftershocks that struck in the state Thursday. The U.S. Geological Survey noted that the biggest tremor struck at 9:51 a.m. local time (1:51 p.m. ET), centered some 80 miles northwest of Anchorage. Its large magnitude was balanced out, somewhat, by how far down it occurred -- 64 miles deep, according to the USGS. Normally, we don't have large magnitude quakes this deep, said Alaska Earthquake Information Center seismologist Natalia Ruppert, noting that the tremor was felt strongly in Fairbanks and as far south as Kodiak. Because it was that deep, it didn't cause as much damage as a shallower quake..
