Volcanic eruptions triggered dawn of the dinosaurs
(Huge pulses of volcanic activity are likely to have
played a key role in triggering the end Triassic mass
extinction, which set the scene for the rise and age
of the dinosaurs, new Oxford University research
has found.)

Crystals once deep inside a volcano offer new
view of magma, eruption timing
(Volcanologists are gaining a better understanding
of what?s going on inside the magma reservoir
that lies below New Zealand?s Mount Tarawera
volcano. They?re finding a colder, more solid
place than they thought, according to research
published today in the journal Science.)
