UTTERLY SURREAL LOW ANGLE GLACIER SLIDE!! 😮😱

On Saturday at 11:00 am, a 2 km-long, 25 m-high, and 150-200 m in width section detached off the Ismoil Somoni Glacier (Tajikistan) and slid down the gorge! 🧊🌊

Published in #GJI Geophysical Journal International: "Fault creep in the fluid-rich Kura Basin, Azerbaijan, imaged with InSAR", Johnson et al. This is Fig. 11: read the paper at academic.oup.com/gji/article/... @oxfordacademic.bsky.social @royalastrosoc.bsky.social

Perspective view showing merged topography and bathymetry for the South Caspian Basin and its surroundings, with the coastlines shown as thin black lines. Faults are mapped with solid lines for higher confidence and dashed lines for lower confidence. NE-SW trending folds in the deeper parts of the basin are shown using dashed lines with diamond decorations. Large submarine landslides visible in the bathymetry are highlighted with translucent polygons. GNSS data from Kadirov et al. (2014) shows the convergence of the Kura Basin with Eurasia taken up by the KFTB and the Caucasus. The triangular region bounded by the Alat Fault and the Sumquayit Fault is moving eastward relative to the Kura Basin, and appears to extrude into the SCB, possibly contributing the folding of offshore sediments. The South Caspian Basin (SCB) velocity vector located offshore is from Dodds et al. (2022) who used the rates of the basin-bounding faults to infer the velocity of the basin.

Section 👇 from Shnizai & Walker in Tektonika 2024 @wearetektonika.bsky.social shows structure of Jalalabad basin, E #Afghanistan.
It's not right across the recent #earthquake but more to the W. The earthquake may have occurred on a thrust fault equivalent to the one to the left of the section. 1/2 ⚒️

Geological cross section across the Jalalabad basin shows several thrust faults dipping to the north-west

"It might never happen..." Remembering forgotten earthquakes in Central Asia

Where in the world do earthquakes pose the greatest risk? Japan, perhaps...or California? When devastating earthquakes hit the news headlines, they implant themselves in our memory, and we create a long-lasting association between the location and the event. But what about the earthquakes that lie outside of living memory? Are the locations of these events perceived to hold the same degree of risk? In this film, Professor Richard Walker and Dr Neill Marshall from Oxford's Department of Earth Sciences share their work on the forgotten earthquakes of Central Asia, and explain the societal implications of natural disasters that have faded into the past.

The magnitude of destruction after the 3:24 pm collapse of Birch Glacier is immense! 😱

All the forest has been razed and the ice/wood/debris dammed the Lonza river 🌊

Some buildings of Blatten are buried 🏠

These deep water sources are likely to be increasingly important, but we know so little of their global distribution due to lack of data and study. Repurposed industrial data may hold the key!

Two paleoseismic trenches near Goychay and Agsu, Azerbaijan provide evidence of at least three surface rupturing events Events occurred 334–118 BC, AD 1713–1895, and AD 1872–2003. The latter two ...

My first post on here. A view of folded basin sediments viewed across the waters of the Toktogul reservoir, #Kyrgyzstan. I am going to start putting on news, field photos, updates relating to #earthquake research with a central Asia focus.
