  • Seafloor sediments appear to enhance Earthquake and Tsunami danger in Pacific Northwest
    on November 20, 2017 at 5:45 pm

    The Cascadia Subduction Zone off the coast of the Pacific Northwest has all the ingredients for making powerful earthquakes -- and according to the geological record, the region is due for its next 'big one.' A new study has found that the occurrence of these big, destructive quakes and associated devastating tsunamis may be linked to compact sediments along large portions of the subduction zone. […]

  • High tsunami danger in Alaska, perhaps elsewhere
    on August 1, 2017 at 2:17 pm

    Scientists probing under the seafloor off Alaska have mapped a geologic structure that they say signals potential for a major tsunami in an area that normally would be considered benign. They say the feature closely resembles one that produced the 2011 Tohoku tsunami off Japan, killing some 20,000 people and melting down three nuclear reactors. Such structures may lurk unrecognized in other areas of the world, say the scientists. […]
