    Testing the Speed of Lava: What It Says about Escape Times & Mars

    Elise Rumpf’s lava flow simulations are yielding new details about the velocity of lava over different surfaces. They may also hold clues about the surfaces of other planets.

  • Mudslides: Forecasting Risk

    Landslides kill thousands of people each year but because they’re often triggered by earthquakes or heavy rains, the danger remains poorly understood. “In densely populated areas, landslides take no prisoners,” said Art Lerner-Lam, a scientist at Columbia University’s Lamont-Doherty Earth Observatory.  “They’ll wipe out an entire village at once. Even a small landslide can kill…
