Quick recap from field suvey of yesterdays M5.8 earthquake in NV. no surface rupture observed after several transects across aftershock pattern. Lack of surface cracking in epicentral area. Minor bank failures, lateral spread, and liquefaction features along Walker river.
Please consider applying - there have been some amazing geologists in this position over the years! including @collett_camille @FaultyAndSalty @nadinegrr @faultjumper oh and Golden isn't a bad place to spend some time 🏔️🌻🚵♀️⛷️🏂🏃♀️🌻🏔️🍺
Job alert 🚨 Do you love active tectonics, GIS, fieldwork, data analysis, and working in a team? USGS Golden is hiring a geologist! See this link for job details and application information: usajobs.gov/job/780739200#…
Ha, looks like the airship hangar and airstrip are built right next to an active fault. Wonder what the fault setbacks for stealth balloons are 😂 #BlackSky #oops
#BREAKING: $BKSY releases the 1st & only #satellite image of an alleged airship at a military base in #China. The rare image was captured on Nov. 4, 2022 at 9 a.m. local time at the Korla East Test Site. Read the full release here: blacksky.com/2023/05/01/bla… #BlackSky #OSINT
Precise, NLL-SSST-coherence earthquake relocations for the 2023 Mw7.8 and Mw7.6, Kahramanmaraş-Gaziantep, Turkey earthquake sequence (including 2020 Mw 6.8 Elazığ, Turkey sequence). Seismic arrival data from @AFADBaskanlik. Details & catalog available at: doi.org/10.5281/zenodo…
Woah, look like you can see the slope failure happen here 😧

Todays big rupture 7.8 m of concrete wall. Also, displacement cutting off a drainage ( classic shutter ridge)
Uphill facing fault plane, faulted terrace with thrashed village in background, and ruptures extending along linear valley .
Check out Offset rock mound by quakedr in #3D, #VR or #AR skfb.ly/oEtRF via @sketchfab we are chasing the end points of the 7.6 eq. This displaced rock mound is near the NE end. @akyuz24 @CengizZabci @tsancar @DrWendyRocks @rangefront @mrbrianolson @Stef_EQ_Geology

~now with pretty radar~ Turkiye surface rupture mapping fast and free! It's wildly preliminary, but hopefully getting this out quickly supports local work. doi.org/10.5066/P985I7… (thank you team, tagged here)

I was diagnosed with cancer in April. Unfortunately, chemotherapy, radiation, and immunotherapy couldn’t tame this, and my medical team is now focused on keeping me comfortable while I spend the last chapter of my life with my partner, family, and friends. 1/4
For a long time geoscientists have been quoting M7.5 for the 1770 Haiti earthquake, but based on fairly cursory earlier analysis of mostly secondary sources. A new study based on detailed original sources sheds new light on this important event. 1/ pubs.geoscienceworld.org/ssa/bssa/artic…
📣new paper📣 Precipitation rate is a major control on the observed decay in preservation of large, cumulative offsets on strike-slip faults @KlingerYann @rangefront @runr447 & I explore at doi.org/10.1130/G50393…
Because we all use offset markers in active tectonics studies it is critical to understand what is controling their formation and preservation. Check out the new paper by N. Reitmann et al. about offsets along strike-slip faults pubs.geoscienceworld.org/gsa/geology/ar…
