Scientists find new source of radioactivity from Fukushima disaster: in sand and groundwater

Scientists have found a previously unsuspected place where radioactive material from the Fukushima Dai-ichi nuclear power plant disaster has accumulated—in sands and brackish groundwater beneath beaches up to 60 miles away. The sands took up and retained radioactive cesium originating from the disaster in 2011 and have been slowly releasing it back to the ocean.

Ecological roulette”: Sea creatures hitchhike across Pacific on tsunami debris

Nearly 300 species of fish, mussels and other sea critters hitchhiked across the Pacific Ocean on debris from the 2011 Japanese tsunami, washing ashore alive in the United States. It is the largest and longest marine migration ever documented.

Impact of 2004 Asian tsunami could have been reduced with mangroves

Many of Indonesia’s mangrove forests were cleared before 2004 for shrimp farms (aquaculture) – subsequent research showed that mangroves and other forests could help protect coastlines and people from the force of tsunamis, hurricanes, and rising sea levels.

NASA Study Challenges Long-held Tsunami Formation Theory

A new NASA study is challenging a long-held theory that tsunamis form and acquire their energy mostly from vertical movement of the seafloor.
