Effect of Mainshock Selection, Earthquake Catalog and Definition on Foreshock Rate Estimates in Southern California Open
Estimates of the percentage of moderate to large crustal earthquakes (mainshocks) that have foreshocks (the foreshock rate) vary widely: Recent estimates in Southern California using an enhanced catalog range between 19% and 72%. Enhanced …

Cleaving the Halqeh-ye-nur diamonds: a dynamic fracture analysis Open
The degree of surface roughness and clarity with which a surface in a brittle material can be formed via fracture is known to be related to the speed of the propagating crack. Cracks traversing a brittle material at low speed produce very …
