Frontiers Tephra without Borders Far-Reaching Clues

This review is intended to highlight recent exciting advances in the study of distal (100 km from the source) tephra and cryptotephra deposits and their potential application for volcanology. Geochemical correlations of tephra between proximal and distal locations have extended the geographical distribution of tephra over tens of millions square kilometers.

Active Andean volcanism its geologic and tectonic setting

Variations in the rate of subduction erosion and subduction of continental crust significantly affect not only Andean magma chemistry, but also the along-strike intraplate mechanical coupling in the subduction zone and the dynamics of mountain building in the Andes.

A n interesting article titled Cretan tools point to 130,000-year-old sea travel, dated January 3, 2011 states that a group of archaeologists found evidence of the first sea voyage by humans, and note this not modern Homo sapiens like us, but ancient, archaic hominids. This finding adds proof to the notion that Homo erectus was a sailor and could have used boats to reach America and Australia.
