Several months ago, over a period of ~22 hours, I wrote down some thoughts that have been banging around in my head for the past few years. @geomorphica.bsky.social have just published those thoughts. #GeospatialRevolution 🧪⚒️❄️ journals.psu.edu/geomorphica/...

A perspective view of a river valley, with the lower elevation parts represented by a lidar hillshade (from open access BC Lidar portal) and the remainder from the ESRI satellite basemap. Various features, including a landslide and ancient meanders on the river terraces are visible in the lidar but not easily interpreted from the satellite imagery.

Just watched @aramfathian.bsky.social on Australian ABC talking about climate change, retreating glaciers, steep mountainsides, and mega, and I mean MEGA, tsunamis. youtu.be/KSBtsXGiu1Y I know @michaelemann.bsky.social had some interest in this.

Initital estimates of the landslide mass came from the seismic data, but then @aramfathian.bsky.social @ucalgaryscience.bsky.social built very high-resolution pre- and post-landslide digital elevation models using @planet.com and Vantor/Maxar imagery.

HERE IT IS! In August 2025, a massive landslide brought a big chunk of mountainside into the Tracy Arm fjord in Alaska, causing the second-largest tsunami ever recorded. My latest for @eos.org is the story of the forensic investigation, and why the culprit is climate change: 🧪

eos.org

The Forensics of a Skyscraper-Sized Tsunami - Eos

A landslide in Tracy Arm Fjord in Alaska created the second-largest tsunami on record. A new analysis links this abrupt event to the retreat of a glacier and, ultimately, to climate change.

One of the neat things was that the seiche (sloshing back and forth of water within the fjord) continued for over a day and we could record the seismic signal that was generated, using seismometers all around the world.

A vanished Holocene lake once covered Central Iran, a region now defined by deserts. Lake level fell not in one collapse, but through climate-driven pulses of expansion and contraction. Alexander the Great’s route skirts its margins. 🔗 journals.sagepub.com/doi/10.1177/...

Map of Iran showing reconstructed paleoshorelines of a large Holocene lake in the Central Plateau. Blue and brown contours outline the former lake extent. Alexander the Great’s march route is shown as a black line that follows the basin margins rather than crossing the reconstructed lake.

This is a highly useful thread outlining practical tips and unwritten rules in academic applications. Details that are often overlooked but are genuinely critical for navigating each stage of the process. If you are applying, read carefully and keep this in mind as you prepare your materials. 📌📄

Large landslides on the southwest side of Mt King George. The main debris lobe on the right is approximately 1000 m wide. The elevation difference between the peak and glacier is approximately 1900 m.

Landslides on the west side of Mt King George. The central debris lobe is 500 m wide.

Large landslide on the southwest side of Mt King George. The main debris lobe is 1800 m wide, and material traveled approximately 6 km from the source area.

🧪⚒️ A M5.6 earthquake struck southern Iran earlier today, causing dozens of injuries and damaging hundreds of homes. This was an unusual earthquake: it occurred on a nearly horizontal fault. But while earthquakes like this are rare, this hazardous fault is well known to geologists!

Bluesky debut—let’s shake things up (pun intended)! 🌍💥 Today’s M5.6 EQ in SW Iran highlights hazards of sub-horizontal detachment faults, introduced in studies like Barnhart et al. (2018). Fathian et al. (2021) show EQs along both mid-crustal décollement and upper crustal detachment in Zagros.
