The North American plate is a medley of geological parts that protrude into Earth’s mantle like tree branches frozen into the surface of an iced-over lake. Research from the University of Texas at Austin has proposed a new method to map these ‘frozen-in’ layers of the tectonic plate and reveal how it interacts with the […]
Remembering the Apollo moon landings: Yosio Nakamura and the birth of planetary seismology
By Constantino Panagopulos Fifty years ago, when Neil Armstrong and Buzz Aldrin became the first humans to walk the surface of the moon they left behind a seismometer – a bulky instrument about the size of a milkcrate whose purpose was to detect moonquakes. Yosio Nakamura was one of the scientists involved in preparing the […]
New NSF Grant Awarded to Study Earth’s “Flat Slabs”
A $2.7 million multi-disciplinary, multi-institutional NSF-Frontiers of Earth Science grant has been awarded to a team led by Carnegie’s Lara Wagner to study an active flat slab in Colombia. A flat slab is produced when a tectonic plate descends to depths of about 30 to 60 miles (~50-100 km) then flattens and travels horizontally for […]
Meet The Exploration Geophysics Trailblazers: Part 4
In March this year, students from the University of Texas Jackson School of Geosciences presented research at the annual meeting of the UT-Austin EDGER Forum, an industry consortium that sponsors education and research in exploration geophysics. Research carried out by the group spans laboratory experiments, numerical simulations and field data analysis, a combination that is […]
Ask UTIG: Why Age and Speed Matter for New Oceanic Crust
UTIG’s Gail Christeson talked to EOS about her latest study, which found how the age and spreading speed of ocean crust determine its thickness, porosity and other characteristics. Python and Jupyter notebooks, increasingly important tools for geophysicists, also played a role in the study. Read the full interview on the EOS website.
