These fossil ammonites have lost their outer coating of shell, revealing the iridescent nacre beneath. Now extinct, ammonites were a group of marine mollusks that first appeared about 409 million years ago, persisting until the extinction event that wiped out the dinosaurs about 66 million years ago.

Using a method to better locate the source of weak tremors from regions with complex geological features, researchers found that many tremors originate from the shear zone, an area of high fluid pressure, in the Nankai Trough, which is schematically shown here with structures of tectonic plates and fault lines.

Making sense of commotion under the ocean to locate tremors near...

How rocks rusted on Earth and turned red

Rock samples collected near the Antarctic volcano Mount Erebus, seen here in the distance, harbor fingerprints of Earth’s ancient magnetic field. A new analysis delves into discrepancies between these fingerprints and predictions from a long-standing approximation of the field. Credit: Hanna Asefaw

Several types of dinoflagellates are shown in this microscope image. Some dinoflagellates are classified as nanoplankton, which new research shows have a more important role in Earth’s biological pump than previously thought. Credit: fickleandfreckled, CC BY 2.0
