Observations of stress relaxation before earthquakes [PDF]

open access: yes, 2004
Theory and observations suggest that seismic shear wave splitting, caused by fluid-saturated stress-aligned microcracks, directly monitors low-level deformation before fracturing, faulting and earthquakes occur.

The scatter of time-delays in shear-wave splitting above small earthquakes [PDF]

open access: yes, 2004
Measurements of time-delays in seismic shear-wave splitting above small earthquakes typically display a scatter of often as much as ±80 per cent about the mean. Changes in the average time-delay appear to be related to changes of stress, but applications

The Relationship of Small Earthquakes to Strain Accumulation Along Major Faults in Southern California [PDF]

open access: yes, 1983
Fault-plane solutions for recent small (ML ≤ 4.6) earthquakes in the central Transverse Ranges, California, were determined using an azimuthally-varying crustal model.

Palaeolimnology of Lake Sapanca and identification of historic earthquake signals, Northern Anatolian Fault Zone (Turkey) [PDF]

open access: yes, 2009
Lake Sapanca is located on a strand of the Northern Anatolian Fault Zone (NAFZ, Turkey), where a series of strong earthquakes (Ms >6.0) have occurred over the past hundred years. Identifying prehistoric earthquakes in and around Lake Sapanca is key to a

Coseismic changes in subsurface structure associated with the 2018 Hokkaido Eastern Iburi Earthquake detected using autocorrelation analysis of ambient seismic noise

open access: yesEarth, Planets and Space, 2019
Autocorrelation analysis using ambient noise is a useful method to detect temporal changes in wave velocity and scattering property. In this study, we investigated the temporal changes in seismic wave velocity and scattering property in the focal region ...
