Abstract One of the most seismically active regions in United States, located hundreds kilometers inland from nearest plate boundary, is Intermountain Seismic Belt (ISB). The 6 July 2017 M 5.8 earthquake occurred 11 km southeast Lincoln, Montana, within ISB. This was largest to rupture state Montana since 1959 7.3 Hebgen Lake earthquake. We use continuous seismic data University Network, Region...

This article presents equations for the estimation of horizontal strong ground motions caused by shallow crustal earthquakes with magnitudes Mw ≥ 5 and distance to the surface projection of the fault less than 100 km. These equations were derived by weighted regression analysis, used to remove observed magnitude-dependent variance, on a set of 595 strong-motion records recorded in Europe and th...
