Seismic moment assessment of earthquakes in stable continental regions?I. Instrumental seismicity
TL;DR: In this paper, the seismic moment and moment magnitude of all earthquakes of stable continental regions (SCR) for which instrumental or intensity data exist were determined using polynomial regression analysis.
Recurrence rates and probability estimates for the New Madrid Seismic Zone
Arch C. Johnston,Susan J. Nava +1 more
TL;DR: In this article, an updated frequency-magnitude relation for the New Madrid seismic zone is used to derive conditional probabilities for future, large New Madrid earthquakes, which are contingent on many factors, a number of which remain assumptions because of the lack of a geological or paleoseismological chronology of past New Madrid activity.

The Effect of Large Ice Sheets on Earthquake Genesis
Arch C. Johnston
- 01 Jan 1989
TL;DR: In this paper, it is shown that with a few reasonable assumptions, ice sheets will indeed inhibit earthquakes by stabilizing potentially seismogenic faults in the underlying brittle crust, which may also explain the intense late-glacial faulting in Fennoscandia reported elsewhere in this volume.

A seismotectonic model for the 300-kilometer-long eastern Tennessee seismic zone
Christine A. Powell,G. A. Bollinger,Martin C. Chapman,M. S. Sibol,Arch C. Johnston,Russell L. Wheeler +5 more
TL;DR: Ten years of monitoring microearthquakes with a regional seismic network has revealed the presence of a well-defined, linear zone of seismic activity in eastern Tennessee that produced the second highest release of seismic strain energy during the last decade.

Seismotectonics of the southern Appalachians
TL;DR: More than 100 new or relocated hypocenters obtained from the initial 2 1 2 yr of operation of the Southern Appalachian Regional Seismic Network (SARSN), a 16-station, four-state telemetered network of short-period vertical instruments.
