Geotimes October 2003 Josh Chamot	Earthquake warning tools The ability to forecast a seismic event has been an elusive goal, but researchers are accepting the challenge and are using recent advances in seismic and computational technology to attempt to decipher Earth's subtle clues.
Geotimes October 2003 Naomi Lubick	Vertebrates and tectonics Paleontologists suggested some new twists on tectonics and ecosystems at the annual meeting of the Society of Vertebrate Paleontology. Their ideas might offer answers to some key conundrums regarding extinction, speciation and the global distribution of vertebrate species.
Geotimes October 2003	Settlement reached on coal slurry spill On Oct. 11, 2000, 250 million gallons of coal slurry poured out of an impoundment in southeast Kentucky, gushing into nearby yards, roads, creeks and rivers and destroying life in 75 miles of waterways.
