graphic - The cover of the special issue of AAPG Bulletin containing the seven Permian Basin studies led by researchers at the Bureau of Economic Geology at The University of Texas at Austin. The diagram illustrates the geologic complexity of Paleozoic strata used for wastewater disposal and the relationship to underlying seismogenic basement in the central Midland Basin of west Texas.

map - Generalized map of the Permian Basin showing earthquakes as merged with duplicates removed from the US Geological Survey for the period 2000–2023, Gan and Frohlich (2013) for 2009–2010, the Texas Seismological Network Earthquake Catalog for 2017–2023, and the New Mexico Tech Seismological Observatory for southeast New Mexico for 2019–2023.

photo - August 14th 2023 - "Streets and cars in Bardonecchia, a city near Turin in the Val di Susa mountain valley, were coated in thick, grey sludge following the violent mudslides late on Sunday."

map - A total of 78 catchments having recorded SGF/SFF historical events with assigned ID number.

photo and schematics - (a) Boulder-train deposit for catchment belonging to group CCBR (example from Rio Secco—ID 69). Note low-angle imbricated clasts and absence of matrix. (b) Schematization of cross section, longitudinal section and plan view of levee deposit. (c) Schematization of clasts’ orientation and size distribution in longitudinal section view. (d) Statistical distribution of clasts’ (>20 cm) intermediate axis (b) orientation from up to down slope.

Beautiful capture of network-like patterns known as "force chains"
