‘Coastal Squeeze:’ Massive Loss of U.S. Coastline Tidal Flats Over 31 Years

The entire contiguous U.S. has experienced massive urban expansions and the Atlantic Coast shows outstandingly high rates. Urban expansion has substantially squeezed the space of tidal flats and affected surrounding environments. In new urban areas, tidal flats have undergone considerable degeneration with more significant patterns as they get closer to new urban locations. Tidal flats protect against the ocean’s destructive powers such as hurricanes. Without some inland spaces to move around, they will likely disappear, which will have dire consequences for beachfront communities.

Lori Dengler is a renowned tsunami expert and professor emerita of Geology for Humboldt State University in Arcata, California. She is a member of an alliance of professionals who develop mitigation and outreach programs for coastal areas. She is also co-author of a children’s book about a tsunami boat called Kamome.

Landslide along Alaskan fjord could trigger tsunami

A glacier that had held an Alaskan slope in place for centuries is melting, releasing the soil beneath in what can be described as a slow-motion landslide that could trigger a devastating tsunami, researchers say. In a study published last week, scientists offered some of the first measurements to quantify how the slope is falling there and modeled potential tsunamis.

New paper addresses mix of contaminants in Fukushima wastewater, highlights risks of dumping in ocean

Ten years after the Tohoku-oki earthquake and tsunami devastated Japan’s Fukushima Dai-ichi Nuclear Power Plant, radiation levels have fallen in all but the waters closest to the plant. But a new hazard exists and is growing every day in the number of storage tanks on land surrounding the power plant that hold contaminated wastewater.
