🐘 ICYMI: In the pitch-black chambers of #MountElgon's #Kitum Cave, African #savannah #elephants use their tusks to scrape volcanic rock for #sodium, #calcium, and #magnesium.

Generations of herds have hollowed out these deep mineral chambers, passing down an unusual #mining tradition found nowhere else on #Earth.

“A few days of rain does not change the low groundwater levels after a long drought. To better determine how groundwater systems recover after a drought and which groundwater reserves are most vulnerable, [a] hydrologist… developed a method to classify groundwater systems based on their ability to recover from long drought. With a very high resolution global groundwater model (1 kilometre) it was possible to determine and analyse how a groundwater system responds during a drought and how quickly it can recover. This provides policymakers with the means to better respond to or prevent severe groundwater problems in the future…”

“[The author] investigated the various factors that make the groundwater recover or not after a period of drought by looking at a large range of groundwater drought events around the globe. Climate plays a major role, but at the local level the geology and landscape are additional important factors for drought recovery. Looking at these different drivers, [they were] able to make a classification in groundwater systems. It turned out that the majority of locations has resilient groundwater systems (57%), exhibiting rapid and robust recovery following droughts. Vulnerable (15%) and stable locations are shaped by geophysical constraints and heightened climate variability, whereas unstable regions (26%) are characterised by frequent, successive drought events leading to a reduced drought recovery capacity and strong impacts on the groundwater system…”

“The 2017 Mw8.2 Tehuantepec earthquake is the largest instrumentally recorded normal faulting earthquake in Mexico. It occurred offshore on a reactivated outer rise fault within the Tehuantepec megathrust seismic gap that is within the undefined intersection of the North American & Caribbean & Cocos plates. [The authors] analyze[d] a relocated machine learning generated aftershock catalog that used data from temporary and permanent seismic stations around the Gulf of Tehuantepec to further interpret the rupture process of this earthquake. Similar to other results, [they found] that the earthquake initiated 100 km offshore, running northwest 90 km into the intersection. [Their] findings then show that the rupture jumped 10 km inland as it crossed the trench-perpendicular Tehuantepec Ridge and continued another 60 km before stopping. [They] used finite fault inversions to distinguish between different possibilities for how the fault ruptured. A two-plane normal fault model offset at ridge, best represents the slip. Moment tensors reveal that the first section before the Ridge was highly complex with a large mix of moment tensors. After the jump across the Ridge, the earthquakes are solely thrust mechanism for 60 km. This indicates that the normal slip on the second half of the fault rupture probably over-slipped and the aftershocks represent the stress accommodation. There was a separate N-S trending divergent region at the location where the Tehuantepec earthquake stopped. [They] interpret this to be a break between the remaining sliver of the Caribbean plate and the North American plate…”

China's Zhangye Danxia looks like a painted desert — hills banded in rust-red, gold, green and teal. The stripes are ancient river and lake sediments tinted by iron minerals, laid down over millions of years, then folded and tilted as the Tibetan Plateau rose. Wind and rain sculpted the rest into today's "rainbow mountains."

I'm having a neurodivergent distress moment

Publisher pushed my book of mineral & gemstone legends because marketing doubts it would interest people

And now out of three storytelling gigs in a row the only one groups didn't sign up for is my gemstone legends performance

Did no one tell me that I am the only on who thinks mineral and gemstone legends are interesting? Is this something everyone else thinks is weird to be excited about?

🐘 WATCH: In the pitch-black chambers of #MountElgon's #Kitum Cave, African #savannah #elephants use their tusks to scrape volcanic rock for #sodium, #calcium, and #magnesium.

Generations of herds have hollowed out these deep mineral chambers, passing down an unusual #mining tradition found nowhere else on #Earth.
