Scale of Volcanic Eruptions Appears to Hinge on First 10 Seconds of Bubble Growth in Magma
October 16, 2012 — New research suggests the difference between a small or large volcanic eruption depends on the first 10 seconds of bubble growth in molten rocks. The findings point to a need to develop volcanic ... > full story -
Ice Age Polarity Reversal Was Global Event: Extremely Brief Reversal of Geomagnetic Field, Climate Variability, and Super Volcano
October 16, 2012 — Some 41,000 years ago, a complete and rapid reversal of the geomagnetic field occured. Magnetic studies on sediment cores from the Black Sea show that during this period, during the last ice age, a ... > full story -
Scientists Identify Trigger for Explosive Volcanic Eruptions
