Boring to study slow earthquakes

Drill preparation. The team prepare the deep-sea drill for use on the seafloor. © 2021 JAMSTEC-IODP Slow earthquakes are long-period earthquakes that are not so dangerous alone, but are able to trigger more destructive earthquakes. Their origins lie in tectonic plate boundaries where one plate subsides below another. Though the causal mechanism is already known, there has been a lack of data to accurately model the life cycle of slow earthquakes. For the first time, researchers use deep-sea boreholes to gauge pressures far below the seafloor. They hope data from this and future observations can aid the understanding of earthquake evolution. The surface of the Earth lies upon gargantuan tectonic plates. The edges of these interact in different ways depending on the plates’ relative movement, composition and density. Where plates collide and one sinks below another is known as a subduction zone, often the site of what are known as slow earthquakes. These are low-frequency earthqua

Something Wiped Out Nearly All Sharks 19 Million Years Ago, New Research Suggests

Something Wiped Out Nearly All Sharks 19 Million Years Ago, New Research Suggests Share A careful arrangement of shark scales, or dermal denticles. (Image: Leah Rubin) Scientists have stumbled upon a previously unknown extinction event that decimated ocean shark populations 19 million years ago. The cause of this sudden die-off, in which global shark populations plummeted by 90%, is a complete mystery. The previously unidentified extinction event, as described in a Science paper published today, was discovered by accident. Elizabeth Sibert, the first author of the study and a postdoctoral fellow from the Yale Institute for Biospheric Sciences at Yale University, detected evidence of the extinction event while studying fossilized fish teeth and shark scales. Sibert was seeking to learn more about these mysterious bits and pieces, collectively known as ichthyoliths, so she, along with co-author Leah Rubin, a student at the College of the Atlantic at the time of the research, embark
