A rock compound slide (Hungr et al., 2014) occurred in Tepehan village near Altınözü (Hatay) and triggered by the February 6, 2023 Türkiye earthquake sequence. This is an example of translational landslide with an area of ~68000 m2. The landslide formed deep cracks along the undulating slope and the lithologies involved are marl and clay-rich limestone.

Exciting paper from Shubham Agrawal out now in PEPI (open access): https://lnkd.in/e2p-s_cR We produce a new intra-plate earthquake catalogue for the Kati Thanda-Lake Eyre region in South Australia using data from the recently deployed Lake Eyre Basin Seismic Array (https://lnkd.in/e9nYiV6W). The localised band of seismicity appears to define the eastern edge of Gawler Craton, and also matches the location of groundwater springs at the surface linked to the Great Artesian Basin. Helium ratios of the fluids from the springs suggest interaction with a mantle derived source, and therefore that the fault producing these earthquakes cuts through the entire crust.

Ptolemaic Kingdom of #Egypt - Ptolemy I Soter This splendid gold type was minted on #Cyprus around the time when the island was annexed to the Ptolemaic kingdom,as described by Plutarch [Demetrios, 35.5], providing a source of materials scarce in #Egypt, like timber and copper. https://lnkd.in/d97yFPVu

Just In: May be “explosive events” February 14, 2024 an earthquake activity has been detected as far away as Las Vegas Nevada raising concerns could Lake Mead Henderson Nevada be the “epicenter’ that breaks in half “HOOVER DAM on the Colorado River? This could be the “OMEN” that fulfills the Mexico U.S. “Treaty” WATER ACT of 1933 to deliver 1.5 million acre feet to Mexicali Valley farmers Juarez Act that was signed but never delivered each year. This is 2024 that is 1933 of “empty promises” what’s new? That is almost 91 years to date. So you do the math and that is 1.5X93=

👉 What you can expect from a poorly designed and detailed shear wall in the event of an earthquake? (Saw this in concepcion, Chile) 👉 Poorly confined boundary elements are destined to fail badly when subject to seismic loads. 🫠 We have a lot of walls like this on North America. The only reason we don’t see this failure is perhaps low seismic activity in many parts.

Fossil seabed from the Upper Muschelkalk with numerous crinoids (sea lilies) Triassic, Muschelkalk, Ladinium, approx. 237 million years old Bodenwerder, district of Holzminden, Lower Saxony, Germany Depositional history: (1) Storm waves led to the deposition of a shell-shell bank and the formation of large ripples; (2) additional clays and clay marls were deposited over the schill limestone; (3) during subsequent storm events, deeper layers that had already solidified were exposed by erosion and were later colonized as solid and hard grounds by sea lilies, among others; (4) further storm events with storm waves tore off the crinoids, which then remained in the ripple valleys and were quickly sedimented.

Continental USA Elevation Map. The tallest summit in the contiguous lower 48 states, Mount Whitney stands at 14,494 feet and is located in the Sierra Nevada Mountains. The lowest point on land in the United States can be found in Death Valley in California. Badwater Basin is an endorheic basin with a depth of 282 ft (86 m) below sea level.

How to apply the geodetic measurements of the 2020 Petrinja (Croatia) earthquake to understanding the regional plate tectonic movement character and its influence on regional security issues? Our paper with the Croatian colleagues is about this:
