EARTH: Setting Sail on Unknown Seas - The Past, Present and Future of Species Rafting

On June 5, 2012, a massive dock made landfall on Oregon's Agate Beach, just north of Newport. The dock carried with it a host of castaways, including as many as a hundred species of mollusks, anemones, sponges, oysters, crabs, barnacles, worms, sea stars, mussels and sea urchins. A placard on the side written in Japanese revealed that the dock had been unmoored from the Japanese coastal city of Misawa during the catastrophic tsunami on March 11, 2011, bringing with it an essentially intact subtidal community of Asian species to the Pacific Northwest. Although natural rafts have likely been ferrying organisms around the planet since the very beginning of life of Earth, the geologically recent advent of human settlement, culture and infrastructure is fundamentally changing the rafting game, as EARTH explores in our March issue.

EARTH: Waves of Disaster: Lessons from Japan and New Zealand

On Feb. 22, a magnitude-6.1 earthquake struck Christchurch, New Zealand, killing nearly 200 people and causing $12 billion in damage. About three weeks later, a massive magnitude-9.0 earthquake struck northern Honshu, Japan. The quake and tsunami killed about 30,000 people and caused an estimated $310 billion in damage. Both events are stark reminders of human vulnerability to natural disasters and provide a harsh reality check: Even technologically advanced countries with modern building codes are not immune from earthquake disasters.
