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.
geologic cross-section - West-to-east profile of the Permian Basin with all relevant operational information projected in from the north and south in depth from surface.
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.

[broadly, a 'seismic' listening technique could help researchers map water movement, moisture levels in soil, with these researchers at Caltech have figured out a way to use vibrations from passing cars to see how much water sits directly beneath the ground’s surface…]

[the adverts on the page make for a LOT of ‘clutter’, but there is some good info here]
“In the realm of geology and engineering geology, seismic reflection is a crucial method for understanding the Earth’s subsurface, unlocking a treasure trove of geological information. This comprehensive guide will take you on a journey through the world of seismic reflection, explaining what it is, how it’s performed, its various applications, and the science behind it…”

“The map could help the agency decide where the first astronauts to the Red Planet should land. The more available water, the less missions will need to bring.
Buried ice will be a vital resource for the first people to set foot on Mars, serving as drinking water and a key ingredient for rocket fuel. But it would also be a major scientific target: Astronauts or robots could one day drill ice cores much as scientists do on Earth, uncovering the climate history of Mars and exploring potential habitats (past or present) for microbial life.…”
