The Theory of Earthquakes in Signalling Severe Political Events [PDF]

open access: yes
This research seeks to conceptualise the use of an earthquake forecasting theory to signal severe political risks such as wars, coups d’état, demonstrations and revolutions.

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

Southern Cascadia episodic slow earthquakes [PDF]

open access: yes, 2004
Continuous GPS and seismic data from northern California show that slow earthquakes periodically rupture the Gorda‐North America plate interface within southern Cascadia. On average, these creep events have occurred every 10.9 ± 1.2 months since at least

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.

Temporal gravity anomalies observed in the Tokai area and a possible relationship with slow slips

open access: yesEarth, Planets and Space, 2018
The water in Earth’s mantle is closely related with plate subduction and volcanism. Recent studies revealed that the mantle wedge corner at approximately 30 km depth holds high-pressure water, where many slow earthquakes occur. To quantify how such water

Data from: Contained Laboratory Earthquakes Ranging From Slow To Fast

open access: yes, 2019
Loading a 3-meter granite slab containing a saw-cut simulated fault, we generated slip events that spontaneously nucleate, propagate, and arrest before reaching the ends of the sample. This work shows that slow (0.07 mm/s slip speeds) and fast (100 mm/s)

The influence of the brittle-ductile transition zone on aftershock and foreshock occurrence

open access: yesNature Communications, 2020
Earth surface continues to slip after large earthquakes at a slow velocity for a period of a year or more. In this study, the authors show how such slow slip before and after large earthquakes relates to the interaction of the brittle zone of the fault ...

Breaking up the hanging wall of a rift-border fault: The 2009 Karonga earthquakes, Malawi [PDF]

open access: yes
The southern East African Rift has an unusually large seismogenic thickness (35–40 km), which is responsible for wide tilted basins and extremely long faults with the potential for M7-8 normal-faulting earthquakes.

Effects of episodic slow slip on seismicity and stress near a subduction-zone megathrust

open access: yesNature Communications, 2021
Large slow slip earthquakes and tremor occur in subduction zones near the locked megathrust. Combined analysis of changes in slab seismicity and stress field near the times of such slow slip events highlights the role of fluid in promoting slow slip.

Defining the Relationship between Seismicity and Deformation at Regional and Local Scales [PDF]

open access: yes, 2013
In this thesis, I use source inversion methods to improve understanding of crustal deformation along the Nyainquentanglha (NQTL) Detachment in Southern Tibet and the Piceance Basin in northwestern Colorado.
