Large shallow earthquakes can induce changes in the fluid pore pressure that are comparable to stress drops on faults. The subsequent redistribution of pore pressure as a result of fluid flow slowly decreases the strength of rock and may result in delayed fracture. The agreement between computed rates of decay and observed rates of aftershock activity suggests that this is an attractive mechanism for aftershockss. 

Spatiotemporal characteristics of aftershock sequences in the South Iceland Seismic Zone: interpretation in terms of pore pressure diffusion and poroelasticity

In seismology numerous observations indicate a relationship between pore pressure in the Earth's crust and the occurrence of earthquakes. In this paper we study aftershock sequences in the South Ic

The pre-earthquake dilatancy, postulated to explain certain premonitory seismic velocity changes, may provide a preferred direction of groundwater flow persisting after the occurrence of a shallow

Premonitory Changes in Seismic Velocities and Prediction of Earthquakes

Large premonitory changes in ratio of seismic P and S velocities correlate with time of occurrence and size of earthquakes at Blue Mountain Lake, New York. These changes may be related to the opening

Regularity and complexity of aftershock occurrence due to mechanical interactions between fault slip and fluid flow

SUMMARY A sequence of aftershocks is modelled assuming fluid migration in a narrow, porous fault zone formed along a vertical strike-slip fault in a semi-infinite elastic medium. The principle of the

Aftershocks and Pore Fluid Diffusion Following the 1992 Landers Earthquake

[1] We model the evolution of regional stress following the 1992 Landers earthquake in order to test the importance of pore fluid flow in producing aftershocks. Rising fluid pressure due to pore

Aftershocks resulting from creeping sections in a heterogeneous fault

We show that realistic aftershock sequences with space‐time characteristics compatible with observations are generated by a model consisting of brittle fault segments separated by creeping zones. The

Mechanical Interactions between Fluid Flow and Fault Slip

It is now widely believed that fluids exert significant effects on earthquake faulting. Recently, considerable attention has been directed to the effects of fluid migration on the spatio-temporal

Physics of Aftershocks in the South Iceland Seismic Zone Insights into the earthquake process from statistics and numerical modelling of aftershock sequences

In seismology, an important goal is to attain a better understanding of the earthquake process. In this study of the physics of aftershock generation, I couple statistical analysis with modelling o

Loading rates in California inferred from aftershocks

We estimate the loading rate in southern California and the change in stress induced by a transient slip event across the San Andreas fault (SAF) system in central California, using a model of static

Control of pore fluid pressure diffusion on fault failure mode: Insights from the 2009 L'Aquila seismic sequence

[1] The MW 6.13 L'Aquila earthquake ruptured the Paganica fault on 2009/04/06 at 01:32 UTC, and started a strong sequence of aftershocks. For the first four days, the region north of the hypocenter



Stick-Slip as a Mechanism for Earthquakes

Stick-slip often accompanies frictional sliding in laboratory experi ments with geologic materials and may represent stick slip during sliding along old or newly formed faults in the earth.

High-Pressure Mechanical Instability in Rocks

At a confining pressure of a few kilobars, deformation of many sedimentary rocks, altered mafic rocks, porous volcanic rocks, and sand is ductile, in that instabilities leading to audible elastic

Model and theoretical seismicity

abstract A laboratory and a numerical model have been constructed to explore the role of friction along a fault as a factor in the earthquake mechanism. The laboratory model demonstrates that small


Promise of resolving the paradox of overthrust faulting arises from a consideration of the influence of the pressure of interstitial fluids upon the effective stresses in rocks. If, in a porous rock

General Theory of Three‐Dimensional Consolidation

The settlement of soils under load is caused by a phenomenon called consolidation, whose mechanism is known to be in many cases identical with the process of squeezing water out of an elasticporous
