Postdoc Appreciation Week continues with Dr. Elhanan Harel, a new postdoc who recently joined Marisa Palucis's group. His research focuses on rivers and flow systems. See his last paper here: (doi.org/10.1073/pnas...)

This is the second video when the first one was just last year. Such videos will become more and more common with future earthquakes, and I wonder which country will be the first to deploy a dedicated network of CCTV cameras along active fault lines.

Hard to believe I’m even writing this. Meteorological summer hasn’t even begun, yet Paris, France has already logged more days above 32°C than its annual average.

A thread on this paper! 🧪⚒️ The Tintina fault is a major right-lateral fault, stretching ~1000 km across the Yukon, and having slipped a total of ~430 km in its lifetime. It's generally thought to have been inactive since the Eocene.

Regional topographic map showing the location of the Tintina fault in the Yukon. Black dots show earthquake epicentres and blue arrows show GPS velocities recording crustal deformation. Blue, yellow and pink polygons show the extent of ice in three past glaciations. White box encompasses the study area in northern Yukon near Dawson City

The tragic landslide in Blatten gives me the excuse to tell you the story of how we found out Ice Ages existed. It's a cool story and the most important bit is rather similar to what's happening now.

#MSH45 | The Blast Let's back up for a moment. 3.3 billion cubic yards of rock and ice crashing downslope, the landslide buries the North Fork Toutle Valley in debris up to 600 feet deep. Behind it, A turbulent cloud of ash, pumice, superheated gas, and pulverized rock.

Photograph by Keith Ronnholm showing the initial blast of Mount St. Helens on May 18, 1980. A dense, dark gray ash plume erupts from the volcano’s north flank, billowing upward and outward. The foreground is lined with evergreen trees and a flat ridgeline, with a clear view of the mountain’s collapse and early lateral explosion.

Second photo by Keith Ronnholm capturing the growing eruption plume. A massive, light-gray ash cloud has expanded across the sky, dwarfing the volcano and the surrounding forest. The plume appears to boil and churn, filled with texture and force. Trees in the foreground remain undisturbed—for now.

Close-up photo of the advancing pyroclastic surge taken by Keith Ronnholm. Dense lobes of ash, rock, and superheated gas cascade down the slopes of Mount St. Helens, filling the valley with towering, cauliflower-shaped clouds. A large fir tree frames the left side of the image, underscoring how close the blast is.

Photograph by Keith Ronnholm capturing the ash cloud as it overtakes the landscape. The bottom of the frame is filled with bulbous, gray pyroclastic material; above it, a dark, turbulent sky swirls with ash and debris. Tree tops in the foreground appear small against the immensity of the blast.

Two features that clearly demonstrate the on-fault displacement field surrounding rupture propagation are the plant next to the wall on the left and the gate itself. Since rarely do seismic stations located so close to the fault (meters away!), these features offer unprecedented observations: 🧵⚒️🧪

Notice anything? 🧐 One tree-ring stands out here, with very pale latewood! 🤍 It's the famous year 536 CE, one of the coldest of the Common Era! 🥶 Early that year, a volcanic eruption caused a veil of aerosols that reduced solar radiation and cooled temperature 🌋 Subfossil larch, Aletsch Gl., CH

Close up picture of tree rings from a subfossil larch retrieved from glacial sediments at Aletsch Glacier. It shows nicely-defined annual rings, one of which has a peculiar colour due to a volcanic eruption in 536 CE that caused one of the coldest year of the last millennia. The ring the tree produced that year has thinner cell walls and lower density than a normal ring

#FridayFold (Probably) Cretaceous carbonates tightly folded to a recumbent fold. Honestly I have no idea of what created this fold, aside from that being is an area of left-right extension and normal faulting. Really puzzling. On the Nuweiba-Taba road, Sinai peninsula

The middle building is moving a lot more than the shorter & taller ones either side. It’s a real world example of the BOSS model simulation - how an earthquake can resonate with buildings that have matching natural frequencies, and seemingly leave others unaffected. www.LinkedIn.com/posts/mehrta...
