Scientists who drilled deeper into an undersea earthquake fault than ever before have found that the tectonic stress in Japan’s Nankai subduction zone is less than expected, according to a study from researchers at The University of Texas at Austin and University of Washington. The findings, published in the journal Geology, are a puzzle because… Continue Reading Deepest Scientific Ocean Drilling Sheds Light on Japan’s Next Great Earthquake
Demian Saffer to Give AGU’s 2022 Francis Birch Lecture
Demian Saffer is to receive the American Geophysical Union’s Francis Birch Lecture, an award that recognizes significant contributions to the study of the Earth’s interior and is among the highest honors given to scientists within the field of tectonophysics. According to AGU, the award, which is named after renowned American geophysicist Francis Birch, is “bestowed… Continue Reading Demian Saffer to Give AGU’s 2022 Francis Birch Lecture
Mystery crater potentially caused by relative of dinosaur-killing asteroid
Originally published in The Conversation. The ocean floor is famously less explored than the surface of Mars. And when our team of scientists recently mapped the seabed, and ancient sediments beneath, we discovered what looks like an asteroid impact crater. Continue Reading Mystery crater potentially caused by relative of dinosaur-killing asteroid
Underwater Snow Gives Clues About Europa’s Icy Shell
Below Europa’s thick icy crust is a massive, global ocean where the snow floats upwards onto inverted ice peaks and submerged ravines. The bizarre underwater snow is known to occur below ice shelves on Earth, but a new study shows that the same is likely true for Jupiter’s moon, where it may play a role… Continue Reading Underwater Snow Gives Clues About Europa’s Icy Shell
Coastal Glacier Retreat Linked to Climate Change
More of the world’s coastal glaciers are melting faster than ever, but exactly what’s triggering the large-scale retreat has been difficult to pin down because of natural fluctuations in the glaciers’ surroundings. Now, researchers at the University of Texas Institute for Geophysics (UTIG) and Georgia Institute of Technology have developed a methodology that they think… Continue Reading Coastal Glacier Retreat Linked to Climate Change
