  • Sea-level rise in 20th century was fastest in 2,000 years along much of East Coast This link opens in a new windowMar 23, 2021

    The rate of sea-level rise in the 20th century along much of the U.S. Atlantic coast was the fastest in 2,000 years, and southern New Jersey had the fastest rates, according to a new study.

  • Melting glaciers contribute to Alaska earthquakes This link opens in a new windowMar 18, 2021

    Glaciers in Southeast Alaska have been melting since the end of the Little Ice Age, many of which are in close proximity to strike-slip faults. When these glaciers melt, the land begins to rise, and the faults they'd previously sutured become unclamped. In this study, scientists determine this process has influenced the timing and location of earthquakes with a magnitude of 5.0 or greater in the area during the past century.

  • A new view on plate tectonics This link opens in a new windowMar 17, 2021

    Along submarine mountain ranges, the mid-ocean ridges, forces from the Earth's interior push tectonic plates apart, forming new ocean floor and thus moving continents about. However, many features of the processes summarized under the term plate tectonics are still unclear. New research assigns transform faults which offset mid-ocean ridges a completely new role in plate tectonics.

  • When volcanoes go metal This link opens in a new windowMar 17, 2021

    What would a volcano - and its lava flows - look like on a planetary body made primarily of metal? A pilot study offers insights into ferrovolcanism that could help scientists interpret landscape features on other worlds.
