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.

Hillshaded elevation map of the northern Central Iranian Plateau showing the reconstructed extent of Lake Saveh (blue shading). Orange outlines mark additional paleolake basins. Triangles indicate Paleolithic to Iron Age archaeological sites. A black line traces Alexander the Great’s route along the basin margins rather than across the former lake.

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.

Congrats! Well deserved!

Onshore-offshore evidence for active tectonics and the propagation of the Zagros deformation front into the Persian Gulf The Zagros Mountains in southwest Iran are a young orogen displaying the geodynamic evolution in an active continental collision zone. We combine the …

Folds and faults mapped on land connect directly with growing structures offshore, revealing a deformation front that is still advancing seaward.

Our recent piece captures this transition clearly: an evolving, progressive orogen spanning land and sea, actively shaping the modern morphology.

The Zagros orogen does not end at the shoreline.

Our study shows that active deformation continues offshore, beneath the shallow waters of the Persian Gulf.

Still trying to calculate the conversion rate for 8K at 60fps.

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. 📌📄

Strongly recommend this opportunity with the waterSHED Lab. An excellent place to do graduate or postdoc research. 🌊🏔️

Landslides on the arete between Mt Vancouver and Mt Logan. Elevation difference between the central peak and the glacier is 500 m.

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.

On FB, Yukon Geological Survey posted some spectacular photos of landslides & snow avalanches triggered by the magnitude 7.0 earthquake on Dec 6 in the St Elias Mountains. Here are some of my favs. @geocron.bsky.social @theronfinley.bsky.social @davepetley.bsky.social @ksvenenvig.bsky.social 🧪⚒️

Sidekick status happily accepted.

New paper today in @science.org focused on unraveling the chain of events that led to the 2023 Teesta disaster, which resulted in about 130 people either dead or missing in Sikkim, India. Short thread to follow. 🧪⚒️ doi.org/10.1126/scie...

Glad to share our paper published in the journal “Science” titled “The Sikkim flood of October 2023: Drivers, causes and impacts of a multihazard cascade.” www.science.org/doi/10.1126/...

Hard to tell. Have to remove the topographic phase first

M5.6 earthquake strikes the Zagros mountains of Iran An unusual low-angle thrust event

🧪⚒️

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.
