Research Highlights
Earth's core may be hotter than scientists thought - as shown by a new method to measure the melting point of iron under extreme pressure. Jennifer Jackson's group squeezed samples of iron to tremendous pressures using diamond anvil cells, and then heated the samples further using infrared laser beams. They found that iron at pressures found at the Earth's core needs a higher temperature to melt than previously thought.
Creeping fault segments, may, in some cases, contribute to massive earthquakes - as shown by new earthquake fault models developed by Nadia Lapusta and Hiroyuki Noda. They hypothesize that this is what occurred in the 2011 magnitude 9.0 Tohoku-Oki Japan earthquake, which was unexpectedly large.
