SUMMARY:Hazardous Earth: How our planet is trying to kill us - Ekbal Hussa

DTSTART:20120125T210000Z

CONTACT:Julian Willis
DESCRIPTION:The surface of the Earth consists of a finite number of rigid
  interlocking plates. The internal engine of the Earth which drives all dy
 namic processes inside the Earth ensures that these plates are constantly 
 moving relative to each other. The model that describes the incessant moti
 on of these plates is the theory of plate tectonics.\n\nAll geological haz
 ards on Earth are directly or indirectly a result of the motion of the pla
 tes. Over the course of human civilisations millions of lives have been lo
 st due to three of these hazards: volcanic eruptions\, earthquakes and tsu
 namis. These are the killer three. The focus of this talk will be on these
  three natural events.\n\nAlthough not the main aim of the talk\, I will b
 riefly discuss the mechanisms by which these events occur and why they occ
 ur in the places they do. I will concentrate on the effects of these hazar
 ds on human populations. How and why people die in earthquakes. Why do peo
 ple live near volcanoes? The talk will finish with a discussion of how lo
 ss of lives can be prevented/limited.
