Ah, yes a rock from the Middle-Absurdian Period on Mars...

🥳🥳🥳 Thrilled to be part of this new effort to connect flood hazards to health risks through community-engaged research linking hydrology, microbiology, anthropology and data science. We’re seeking PhD students + postdocs eager to dive in to this convergent research!

In the news at IU: Dr. Brian Yanites (@geomorphyuggs.bsky.social) is a principal investigator in the new Center for Land Surface Hazards, sponsored by NSF. Press release and more details: news.iu.edu/live/news/46...

Big news today! Super excited to be a part of this new initiative. Lots to come, so stay tuned! And follow @clashgeohazards.bsky.social !!!

Can forests damp earthquake waves and thus limit co-seismic landslides? What does this mean for Critical Zone development? Postdoctoral position with Will Struble and a multi-disciplinary team (including me🌲🌲🌊🌳🪾). Position is open until filled. willstruble.com #CZScience #Postdoc

That tsunamigenic landslide is impressive.

Can we now stop saying that once suspended sediment returns to pre-event levels, then the system response is over? Great paper here with relevance to cascading hazards and landscape evolution.

shamelessly made a bluesky account so I could plug my first first-author paper (!) on postfire erosion in steep rocky catchments -- go check her out! www.science.org/doi/10.1126/...

Out Now: August Issue of #GSAToday! Lead article: Multi-agency effort forecasts & mitigates postfire debris flows in Glenwood Canyon, CO—26 in 2021, 3 in 2023, no major injuries. Plus: GSA Connects 2025 updates, GSA news & Wonders of Geology. Read now: geosociety.co/4oqnjlV

This landslide has its own entry on the USGS earthquake site: earthquake.usgs.gov/earthquakes/...

On 21 July 2025, an extremely large rock avalanche occurred in the mountains in Wanrong Township in Hualien County, Taiwan. Initial measurements suggest that this ran out for about 6 kilometres. Image by @planet.com on the Google Earth DEM. An initial description is here:- eos.org/thelandslide...

And maybe we'll trigger an evening of cascading fun with a post-session Hurricane.

OpenTopography is excited to announce a major expansion to its international data catalog with the addition of the High Resolution Digital Elevation Model from Natural Resources Canada. This 1-meter resolution dataset is ideal for a wide range of applications. opentopography.org/news/opentop...

📣 New paper: Quantifying river bed roughness. 💧Multiple metrics are required to fully describe river bed roughness. 💧River beds with differing features can be distinguished using roughness data. 💧Potential implications on flow resistance and sediment transport. 📖 doi.org/10.1029/2024...

I’d add NSF to that list. There is still some basic research needed on flash flooding hydrology and mechanics (eg rheology of the debris fronts) and that is needed to improve forecasts.

Texas Hill Country is scenic – and deadly during storms. Its steep hills and fast-moving water make it one of the most dangerous places in the U.S. for flash floods. A flood on July 4 killed at least 27 people. A hydrologist explains why this keeps happening: theconversation.com/why-texas-hi...

July 2025 marks the 80th anniversary of the "Endless Frontier" report, which led to the establishment of NSF and transformed the US from a science backwater to a global research powerhouse. Will today's congress sustain or abandon that incredible success story? earthcastings.ghost.io/the-endless-...

Storm in the Outer Banks #obxwx

Natural hazards such as earthquakes, fires, and floods can dramatically affect human life and infrastructure. In a new #ScienceReview, researchers argue the need for a unified, interdisciplinary approach to studying cascading land surface hazards. scim.ag/4kbWn60

Just because the storm ends doesn’t mean the danger’s over. Hurricanes, earthquakes and wildfires reshape the land, setting up the next disaster. Scientists call it cascading hazards, and it’s getting worse. By @geomorphyuggs.bsky.social: buff.ly/gUJNZTH #science 🧪

Happy to have provided a climate and atmospheric science perspective to this review in @science.org w/ @geomorphyuggs.bsky.social et al. Climate change-driven alteration of hydrological processes is fundamentally changing how we need to think about hazards and their long tailed consequences.

We're in @science.org! Prof. @geomorphyuggs.bsky.social and colleagues with a review paper on the processes that influence sequences of "cascading" natural hazards (such as debris flows and flooding after a fire), which compound the risk to life and property. www.science.org/doi/10.1126/...

New in @science.org: Natural hazards aren’t “one and done.” They alter the landscape, changing the likelihood of follow-on events. We argue there’s an urgent opportunity for geomorphologists—working with other disciplines—to better understand and forecast cascading hazards.

Just like a kid in the yard. Gotta make ‘em light up.

Scientists race against time in Kentucky, collecting flood data amid funding cuts. The stakes? The future of southern Appalachia. Trump’s budget guts FEMA, NSF & NWS—crippling agencies meant to forecast floods & save lives. Scientists scramble as federal support vanishes. zurl.co/HdX01

Hells Canyon dramatically divides Oregon and Idaho. A study finds that North America’s deepest river gorge was rapidly incised 2.1 million years ago when the Snake River was captured by a tributary of the Columbia River. In PNAS: www.pnas.org/doi/10.1073/...

Seeing Blatten buried again and again, from every angle... Properly staggering! 😮😱

On this Mount St Helens anniversary, let us be reminded that the US Army Corps is only planning on managing the sediment retention structure through 2035. There's still a LOT of sediment moving through that system. Long-tail cascading hazard indeed! www.nwp.usace.army.mil/mount-st-hel...

🎉Thank you National Science Foundation, for all the #NSFfunded #seismological science you support, including the SAGE and GAGE facilities operated by @earthscope.org. Our current understanding of #earthquakes, #volcanoes and #geodesy research would not be possible without you. ⚒️ 🧪

This seems to be the antithesis of ‘efficiency’

And this unit of a trout was just hanging out in the pool upstream of the dam.

Coast Range debris flows are no joke. Great day exploring source to deposit of ~ 1yr old event. W/ @geo-sdo.bsky.social

Move over G.I. Joe

Freshman year field trip to the Mojave. Hiked up Kelso Dunes and decided to become a geomorphologist.
