2024 NASA Solid-Earth Team Meeting

Save the date!

NASA’s Earth Surface and Interior (ESI) focus area will hold the next hybrid Solid-Earth Team (SET) meeting on September 16-18, 2024, at the Omni Shoreham Hotel at 2500 Calvert St NW, Washington, DC 20008. The 2024 SET meeting will focus on collecting community input to inform the next ten-year vision for ESI, building on the 2016 Challenges and Opportunities for Research in ESI (CORE) Report. 

Please indicate your interest in attending in person or virtually and receive additional communications by visiting https://emg-wd.wixsite.com/setm-c2-2024 to RSVP by Thursday, June 20, 2024.

SRL Call for Papers: Focus Section on The OSIRIS-REx Re-entry

Deadline for Submission: 6 January 2025

The 24 September 2023 re-entry of NASA’s OSIRIS-REx Sample Return Capsule (SRC) was only the fifth re-entry from interplanetary space since the end of the Apollo era. It provided a unique opportunity to geophysically observe an ‘artificial meteor’ with known dimensions, speed, and mass. A diverse set of institutions utilized a large number of instruments, including but not limited to, nodal seismic arrays, ground and airborne acoustic sensors, distributed acoustic sensing, GPS sounding, and ionosphere Doppler sounding to record the object’s passage through the atmosphere. Results from these studies have implications for the remote detection and characterization of meteoroids and high-speed artificial objects (e.g., re-entry, orbital debris) on Earth and may inform mission concepts for planetary exploration (e.g., Venus, Mars, Titan, Jupiter). We invite contributions that emphasize geophysical observations of the OSIRIS-REx SRC re-entry and similar events and discuss their broad scientific implications for remote sensing on Earth and beyond.

Deadline for Submission: 6 January 2025

Articles accepted to this SRL Focus Section on Statistical Seismology and Probabilistic Earthquake Forecasting will be published online soon after acceptance and collectively in print in the July 2025 issue. Papers will be reviewed as they are received and published online prior to the print issue.

In preparing manuscripts, authors must follow the SRL author guidelines at www.seismosoc.org/publications/srl-authorsinfo/. Papers must be submitted via the SRL online submission system (www.editorialmanager.com/srl) under the category “Focus Section – OSIRIS-REx.

GSA Field Trip FT140 - The San Andreas Fault through San Gorgonio Pass

We invite you to join us for the one-day GSA Quaternary Geology & Geomorphology Division's Kirk Bryan Field Trip FT140: The Holocene Trace of the San Andreas Fault through San Gorgonio Pass on Saturday, June 21st, at the beginning of the GSA Connects meeting in Anaheim. We will depart the Anaheim Convention Center at 7:30 AM and plan to return at 6:30 PM.

The San Andreas Fault bifurcates into strands through San Gorgonio Pass northwest of Palm Springs. Here, the Mission Creek Strand cuts through Mission Creek Preserve near Desert Hot Springs, where it cuts and/or is overlain by late Quaternary deposits. This field trip will visit locations along the fault within the preserve to decipher the late Quaternary and/or Holocene slip history, where slip rate estimates vary between 0 and >20 mm/yr among researchers. Sites are within ~2 km of the parking area. Site 1 will be a recently dated (OSL) Holocene terrace, which overlies or is cut by the Mission Creek Strand. Site 2 looks at the Mission Creek Strand where it forms an obvious lineation and bench along a canyon wall, where Quaternary sediment has been uplifted and exposed. Here we can observe the San Andreas Fault and discuss the timing of fault slip. Site 3 will be a right-laterally offset channel within Quaternary sediment west of Site 2, where we will discuss OSL dating of alluvial deposits. Specifically, we will discuss the syn- or post-tectonic origin of the inset alluvium. The field trip will depart from Anaheim and participants will be driven via SUV to the Stone Cabin at Mission Creek Preserve, where there are restrooms and a picnic area. From there, Site 1 is an easy 1-km walk. Site 2 will be another ~400-m walk up a low-gradient alluvial surface. Site 3 requires a relatively steep hike another 1000 m beyond Site 1 for those willing and able. Transportation, lunch, and snacks are included. There are bathrooms at the parking lot of the Preserve near stop 1.

Students and Early Career Professionals can apply for a grant to make this trip free, courtesy of GSA Divisions and a new partnership with Chevron.

Registration is $55 and can be purchased during meeting registration or separately on the GSA Bookstore website (https://store.geosociety.org/Bookstore/ItemDetail?iProductCode=FT24CN410).

For additional information, please contact Rebecca Taormina, rtaormina@geosociety.org, GSA Field Trip and Short Program Coordinator.

GSA Session on Plate Margin Tectonics

We invite you to consider submission of a poster or talk in the topical session T152: "Toward Understanding the Spatial, Structural, and Temporal Characteristics of Surface Deformation in Tectonically active Multi-Fault Systems in the American Cordillera and other plate margins" at the upcoming GSA Connects 2024 Conference, to be held September 22-25, 2024, in Anaheim California, USA. This session is co-sponsored by the GSA Quaternary Geology and Geomorphology Division, GSA Structural Geology and Tectonics Division, GSA Environmental and Engineering Geology Division, GSA Geochronology Division, GSA Geophysics and Geodynamics Division, and GSA Soils and Soil Processes Division. We invite presentations related to studies that combine mapping of the surface with other geologic, structural, tectonic, geomorphic, geochronologic, and geophysical data sources and approaches to characterize the spatial and temporal development of complex fault systems in the Cordillera and other active plate margins.  Submissions that link these plate margin tectonic processes to issues of societal relevance, such as seismic and fault-displacement hazard analysis or the development and distribution of water, mineral, and other critical resources, are especially encouraged.

Abstract submission is open until June 18th, 2024.  If you have any questions or want additional information, please contact Chris Menges (cmmenges@usgs.gov) or Andy Cyr (acyr@usgs.gov).
