AZGS geologist Chad Kwiatkowski stands alongside a fresh earth fissure south of Willcox Playa in Cochise County, AZ in February 2023. This new earth fissure is approximately 0.5 miles long and formed in an area with a history of land subsidence and fissures.

Such a great opportunity for undergrads! I loved my NOAA internship back in 2017. And not many geology majors apply!

New paper, I have a very minor role on it, but very thankful for the opportunity. Vadman et al identified and mapped a portion of a 1-2 ka old paleo- multi fault rupture between Landers and Hector Mine, rupturing partially along Calico and likely a Mw 7.4. pubs.geoscienceworld.org/gsa/geosphere/…

Our new paper is out! We constrain the timing, partial extent, and likely magnitude (Mw 7.4) of a prehistoric multifault earthquake rupture on the Calico-Hidalgo faults in the Mojave. So happy to be a part of this work and thankful for everyone involved! doi.org/10.1130/GES026…

Sentinel-1 data now processed by COMET Datasets & Services LiCSAR system for recent Morocco earthquake. Data available for download and analysis from the event page at comet.nerc.ac.uk/earthquakes/us…

Shout out to the miners ⛏️⛰️of Mojave past for giving me the heebie-jeebies while mapping but also kindly exposing some geology

NOW is the time to prepare your workplace for natural disasters and other emergencies. We have the information and resources you need to get started: osha.gov/emergency-prep… #BeReady Readygov

Just in: Biden-Harris Administration announces $80M through Investing in America Agenda to improve flood prediction capabilities. Funding supports NOAA’s efforts to upgrade the National Water Model and expand Flood Inundation Mapping services. noaa.gov/news-release/b…

*New Paper Alert! science.org/doi/10.1126/sc… The implications of our study necessitate a re-assessment of seismic risk in the Puget Sound of Washington. The 🌲s give us a warning of potential earthquake scenarios for the heavily populated region.

Sections and preserved block from the transpressive model a few days back. The dome structure looks cool from the top but the structural style didn’t quite do it for me. True inversion is quite limited within the stress field used.

Big news: USGS scientists & partners have confirmed, with 2 new lines of evidence, that human footprints found in White Sands Nat'l Park show that people lived in North America 21-23,000 yrs ago—much earlier than previously thought! More here: ow.ly/9peJ50PTBGN Imgs: NPS

Happy to announce that you can now use OpenTopography tools to compute topographic change on overlapping datasets in the USGS #3DEP & NOAA Coastal Lidar collections. Dynamically compute landscape change for ~20% of CONUS w/ publicly available #lidar in OT: opentopography.org/news/3dep_noaa…

Just one week left to donate to GSRS 2024! We're over halfway there, help us reach our goal by donating today at crowdfund.vt.edu/project/39427. A big thank you to everyone who has already donated!

I’m really pleased to share the publication of our collaborative study on Slamet volcano! This work was the culmination of my PhD, and represents a big step forward in our understanding of Slamet’s melt storage and eruptive potential: sciencedirect.com/science/articl…

🚨Fully funded PhD position🚨Come work with me and Matthew Fox to unlock secrets of cosmogenic nuclides within river sand. Fieldwork in Hawai'i and Sierra Nevada (US). Labwork EarthSciences UCL London Geochronology Centre and @SUERCNobleGas. Details @ bit.ly/cosmicland

Snow fell all day yesterday and throughout the night on Grandfather Mountain, with totals ranging from six inches to a foot depending on the elevation and location. The park is closed for the day (Tuesday, Jan. 16). We apologize for any inconvenience. 📸: GMSF Staff

Monumental news!  We’ve recently closed on two large acquisitions totaling 473 acres within the Mojave Trails National Monument. At 1.6 million acres, Mojave Trails National Monument is one of the largest national monuments in the lower 48.

Check out my first 1st-author paper from my PhD work to learn about transpressional fault bends in the Mojave Desert of California! So thankful to get this work out and for everyone involved! doi.org/10.1029/2023TC…
