Did deglaciation trigger intraplate seismicity in the New Madrid seismic zone

  title={Did deglaciation trigger intraplate seismicity in the New Madrid seismic zone},
  author={Balz Grollimund and Mark D. Zoback},
We have investigated the interaction between large-scale plate driving forces, lithospheric structure, and the stresses induced by bending of the lithosphere as a result of glacial loading and unloading in the New Madrid seismic zone, eastern-central United States. The modeling shows that the removal of the Laurentide ice sheet that covered large parts of the northern United States until ca. 20 ka changed the stress field in the vicinity of New Madrid and caused seismic strain rates to increase… Expand

Impact of deglaciation on present-day intraplate seismicity in eastern North America and western Europe
The retreat of major ice sheets in North America and northern Europe caused a large-scale isostatic desequilibrium of the lithosphere–asthenosphere system. As a result, formerly glaciated areasExpand
Triggering of New Madrid seismicity by late-Pleistocene erosion
It is argued that the concentration of magnitude-7 or larger earthquakes in the New Madrid seismic zone of the central United States since the end of the last ice age results from the recent, climate-controlled, erosional history of the northern Mississippi embayment. Expand
Stress development in heterogenetic lithosphere: Insights into earthquake processes in the New Madrid Seismic Zone
Abstract The New Madrid Seismic Zone (NMSZ) in the Midwestern United States was the site of several major M 6.8–8 earthquakes in 1811–1812, and remains seismically active. Although this region hasExpand
Geodetic Observations of Active Intraplate Crustal Deformation in the Wabash Valley Seismic Zone and the Southern Illinois Basin
Seismically active intraplate continental settings are characterized by relatively low strain rates, but they nonetheless display evidence of active faulting and seismicity. Examples of theseExpand
Processes and deformation rates generating seismicity in metropolitan France and conterminous Western Europe
Most of metropolitan France and conterminous Western Europe is currently located within the Eurasia intraplate domain, far from major plate boundaries (the Atlantic ridge and Nubia – EurasiaExpand
Is earthquake activity along the French Atlantic margin favoured by local rheological contrasts
Abstract The seismological study of recent seismic crises near Oleron Island confirms the coexistence of an extensional deformation and a transtensive regime in the Atlantic margin of France, whichExpand
The effect of earth rheology and ice-sheet size on fault slip and magnitude of postglacial earthquakes
Abstract Moderate past and present-day seismicity is observed in formerly deglaciated regions of North America and Europe. An understanding of the occurrence of these earthquakes is important forExpand
Reactivation of basement faults: interplay of ice-sheet advance, glacial lake formation and sediment loading
The Emme Delta is a small glacilacustrine delta, which developed on the southern flank of the Wesergebirge Mountains in NW Germany. Shallow shear-wave seismic surveys allow a detailed assessment ofExpand
Space geodetic evidence for rapid strain rates in the New Madrid seismic zone of central USA
Direct evidence for rapid strain rates in the area determined from a continuously operated global positioning system (GPS) network are shown, comparable in magnitude to those across active plate boundaries, and are consistent with known active faults within the region. Expand
A Parametric Analysis of Fault Reactivation in the New Madrid Seismic Zone: The Role of Pore Fluid Overpressure
Earthquakes in Stable Continental Regions (SCR), where localized present‐day tectonic loading is negligible, remain difficult to explain. The New Madrid Seismic Zone (NMSZ) is a type‐locale for suchExpand


Can deglaciation trigger earthquakes in N. America
A spherical, self-gravitating viscoelastic earth model is used to calculate the spatial and temporal evolution of the glacially induced lithospheric stress and fault stability in North America. TheExpand
Tectonic stress within the New Madrid seismic zone

A mechanical model for intraplate earthquakes: application to the new madrid seismic zone
Simulations predict large (5 to 10 meters) slip events with recurrence intervals of 250 to 4000 years and cumulative offsets of about 100 meters, depending on material parameters and far-field stress magnitude. Expand
Slow deformation and lower seismic hazard at the new madrid seismic zone
Global Positioning System measurements across the New Madrid seismic zone (NMSZ) in the central United States show little, if any, motion, and frequency-magnitude relation for seismicity implies that the hazard posed by great earthquakes in the NMSZ appears to be overestimated. Expand
Lithospheric strength and intraplate seismicity in the New Madrid seismic zone
A simple hypothesis is proposed to explain the occurrence of localized zones of tectonic deformation and seismicity within intraplate regions subjected to relatively uniform far-field tectonicExpand
Recurrent Intraplate Tectonism in the New Madrid Seismic Zone
For the first time, New Madrid seismicity can be linked to specific structural features that have been reactivated through geologic time and with structural deformation apparently caused by repeated episodes of igneous activity. Expand
Reconciling Short Recurrence Intervals with Minor Deformation in the New Madrid Seismic Zone
P Paleoseismological data indicate that earthquakes large enough to cause soil liquefaction have occurred several times in the past 5000 years, but pervasive crustal deformation expected from such a high frequency of large earthquakes is not observed. Expand
How faulting keeps the crust strong
Deep drilling and induced seismicity experiments at several locations worldwide indicate that, in general, the brittle crust in intraplate regions is critically stressed, pore pressures are close toExpand
