Preparing for Japan’s Next Tsunami

The Pacific plate is one of many possible tsunamigenic quake sources, and scientists believe the Nankai Trough, another subduction zone much closer to the Japanese coast than the source of 3/11, will produce a similar megaquake and tsunami within the next 30 years.

Tracking Sargassum’s ocean path could help predict coastal inundation events

New research explores how the Sargassum might grow while it is meandering along the currents, not just where it floats, combining both ocean physics and seaweed biology for the first time to understand the distribution patterns. Knowing could eventually help predict its arrival and impact on beaches around the world
