*Samples of rock, sediment from beneath the sea-floor help explain quakes like Japan’s*

New samples of rock and sediment from the depths of the eastern Pacific Ocean may help explain the cause of large, destructive earthquakes similar to the Tohoku Earthquake that struck Japan in mid-March.

Nearly 1,500 meters (almost one mile) of sediment cores collected from the ocean floor off the coast of Costa Rica reveal detailed records of some two million years of tectonic activity along a seismic plate boundary. (more…)

The Smithsonian Tropical Research Institute’s Bocas del Toro Research Station and Galeta Point Marine Laboratory are reporting an anomalous sea temperature rise and a major coral bleaching event in the western Caribbean. Although the U.S. National Oceanic and Atmospheric Administration, NOAA, issued an advisory in July announcing above-average sea surface temperatures in the wider Caribbean region, there had been no clear indication of increased sea temperatures in Panama and the western Caribbean until late August-early September.
