It is important to develop some general knowledge what causes earthquakes, in order to gain a better understanding about the Tangshan event. Earth's crust is broken into major tectonic plates that move towards and away from each other in different directions. Debated driving forces behind this movement includes Earth's rotation, gravity related forces and mantle dynamics. Generally, it is accepted that tectonic plates are able to move because of the relative density of oceanic lithosphere and...

The Mapuche (Mäpfuchieu), were known as the Araucanians (araucanos) by the immigrating Spaniards (the term today is often taken by them as a slur). The traditional Mapuche economy was agricultural. Their society is based on extended families, each led by a lonko (chief). In wartime, several families may unite and elect a toqui (Mapudungun toki "axe, axe-bearer") as a common leader. Mapuche origins have widely debated; different scholars at different times have associated their language with t...

Gone are the times when inimical actions by a nation incited a direct response. Today, the e...

In prehistoric times the ancestors of present day Papuan speaking people settled the islands of Melanesia at least to the Solomon Islands and probably to islands further east. Around 4,000 ...

The question remains as to whether the American failure was one of collection or analysis and this is a point which David Kahn and Roberta Wohlstetter come to very different conclusions about. Whilst Kahn advocates the view that the American fai...
Australia was a member of the British Empire although it became a Federation since 1901. This meant that when Britain declared war on 4 August 1914 not only were the French and Russian empires forced to join the British, but Australia as well found itself at war. At the time the Labor leader, Andrew Fisher, assured the British that 'Australians will stand beside our own to help and defend her to our last man and our last shilling.’ Australia, being a newly-created nation with only a r...
