And again it’s almost the start of a weekend! I collected some nice links for you, I hope you like them. Today is Friday and here are your links!
Over 3600 earthquakes have been recorded in Oklahoma since 2009. A recent study finds out that preexisting faults are being reactivated and are capable of generating magnitude 5 to 6 earthquakes in the future. Two fault systems have been identified analyzing the seismicity records: the over 200 km long Wilzetta fault system and the Nemaha fault system. (ht)
Then there was this new paper by Papathanassiou et al. where they evaluate liquefaction potential in the epicentral area of the 2012 Emilia earthquake They correlate the ground deformations with values of LPI (Liquefaction Potential Index) and LSN (Liquefaction Severity Number), based on post-EQ reports and geotechnical data.
I’m pretty sure you all have heard of the Racetrack Playa sliding stones before. (Un)surprisingly, they can also be found at other places like for example at Bonnie Claire Playa. This post provides you with a circular riddle. Go and solve!
The New York Times have produced a cardboard documentary on Alfred Wegener’s findings and scientific struggle, calling it op-doc – an opinionated documentary. I think it’s quite pretty!
I think I linked this 3D visualization of this trench earlier, but the article on paleoseismological trenching toured the internets (on various Facebook walls including ours) this week, so I’m happy to further spread this multi-part article (select – collect – process) on our everyday work. And by everyday work I rather mean sometimes (select), a bit more often (collect), and really every day (process).
Have a nice weekend!
