Rockin' Out is increasing diversity in STEM fields with K-12 education and outreach! Over the last 2 years, @RockinOutUW has reached ~1500 students through lab tours at UW, guided field trips, tables at school STEM nights, and visits to local classrooms. ess.uw.edu/2023/09/increa…

🔔#Earthquake (#földrengés) M4.6 occurred 57 km S of #Sevastopol’ (#Ukraine) 10 min ago (local time 05:42:26). More info at: 📱emsc-csem.org/service/applic… 🌐m.emsc.eu/?id=1275986 🖥emsc-csem.org/Earthquake/ear…

A debris flow in Mount St. Helens' South Coldwater Creek at 8:45 PM on May 14 destroyed a SR 504 bridge and cut off access & power to Johnston Ridge Observatory. The event was caught on seismic data at nearby stations and may have been linked to several days of warm weather. 1/3

The #MagnaEQ 3rd anniversary is tomorrow. This is a great time to remember that we live in earthquake country and can have a large damaging earthquake at any time. Here are some resources to prepare. @BeReadyUtah @UtahEmergency

@ALomaxNet @JudithGeology @AFADBaskanlik Thank you for sharing @ALomaxNet. The relocated aftershocks (red dots) concentrate at major fault bends and in the periphery of large slip patches. The distribution of seismicity helps constrain the depth extent of the ruptures.

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…

.@USGS scientists studying the Seattle Fault zone found a previously unknown scarp that can be traced continuously across part of Bainbridge Island. For more on their findings, presented at @theAGU 2022 Fall Meeting, check out this story by @beccapox temblor.net/temblor/seattl…

The yellow flash is the ionospheric disturbance created by North Korea's ICBM launch and recorded by the GPS network. This open source missile launch detection tool was created by @tylerni7 and @michaelnute, members of the impossibly awesome @ACWPodcast Slack community.

America’s teachers do enormously important and difficult work. It’s time we paid them like it. Join me LIVE from the U.S. Capitol for a town hall on the teacher pay crisis in America. twitter.com/i/broadcasts/1…

Happy to report another release of mapboard-gis.app, version 3.3.0, which, among other improvements, allows drawing maps in 3D! Surprisingly, (and owing to the great work at @Mapbox), this really was trivial to add, even with the editing overlay. 🎉

How can aftershocks help scientists better understand fault systems? Relocation + tomography! In this new #SRL paper, scientists from @INGVvulcani dive into fluids and complex faults related to the 2012 Emilia Seismic Sequence in Northern Italy. doi.org/10.1785/022022…

Geoscientists at Caltech have used micro-seismicity to chart out the structure of sills at depths of 36-43 km that channel magma laterally and upward to recharge the magma chambers of Kilauea and Mauna Loa, demonstrating that they link the volcanoes: caltech.edu/about/news/haw…

Two earthquakes hit Liechtenstein just as lawmakers in the tiny Alpine principality were debating the pros and cons of quake insurance. Police said no injuries or damage were reported. apne.ws/IBYK3cZ

@Juliamorphology @GeoLatinas @tamyaranguiz !!!

@SeismoSue this is SO COOL!!

The Amarillo Zoo captured a strange image outside the zoo in the dark and early morning hours of May 21 (around 1:25 a.m.). Is it a person with a strange hat who likes to walk at night? A chupacabra? Do you have any ideas of what this UAO- Unidentified Amarillo Object could be?
