King (Eds.), The Interdisciplinary Earth: A Volume in Honor of Don L. Anderson (105-121). The Geological Society of America / AGU. https://doi.org/10.1130/2015.2514%2808%29

Several workers have suggested that the locations of melting anomalies (hotspots) and the original locations of large igneous provinces (LIPs) and kimberlite pipes lie preferentially above the margins of two large low-shear-velocity provinces, or LLS... Read More about Hotspots in Hindsight.

The Yellowstone “hot spot” track results from migrating basin-range extension (2015)
Book Chapter
Foulger, G., Christiansen, R., & Anderson, D. (2015). The Yellowstone “hot spot” track results from migrating basin-range extension. In G. Foulger, M. Lustrino, & S. King (Eds.), The interdisciplinary earth : a volume in honor of Don L. Anderson (215-238). Geological Society of America. https://doi.org/10.1130/2015.2514%2814%29%26%238203%3B

Whether the volcanism of the Columbia River Plateau, eastern Snake River Plain, and Yellowstone (western U.S.) is related to a mantle plume or to plate tectonic processes is a long-standing controversy. There are many geological mismatches with the b... Read More about The Yellowstone “hot spot” track results from migrating basin-range extension.

Anthropogenic earthquakes in the UK: A national baseline prior to shale exploitation (2015)
Journal Article
Wilson, M., Davies, R., Foulger, G., Julian, B., Styles, P., & Gluyas, J. (2015). Anthropogenic earthquakes in the UK: A national baseline prior to shale exploitation. Marine and Petroleum Geology, 68(Part A), 1-17. https://doi.org/10.1016/j.marpetgeo.2015.08.023

We review the distribution, timing and probable causes of ∼8000 onshore UK seismic events between the years 1970–2012. Of 1769 onshore seismic events with local magnitudes (ML) ≥ 1.5, we estimate at least ∼21% of these have an anthropogenic origin, a...

Non-Double-Couple Earthquakes (2015)
Book Chapter
Foulger, G., & Julian, B. (2015). Non-Double-Couple Earthquakes. In M. Beer, I. Kougioumtzoglou, E. Patelli, & I. Au (Eds.), Encyclopedia of earthquake engineering (1-31). Springer Verlag. https://doi.org/10.1007/978-3-642-36197-5_290-1

Non-double-couple (“non-DC”) earthquake mechanisms differ from what is expected for pure shear faulting in a homogeneous, isotropic, elastic medium. Until the mid-1980s, the DC assumption underlay nearly all seismological analysis, and was highly suc... Read More about Non-Double-Couple Earthquakes.
