Laboratory Hydrofractures as Analogs to Tectonic Tremors
AGU AdvancesThe fracture of Earth materials occurs over a wide range of time and length scales. Physical conditions, particularly the stress field and Earth material properties, may condition rupture in a specific fracture regime.

Chemical origin of tectonic tremor [PDF]
Nature Geoscience, 2019 Tectonic tremor may ultimately be caused by in situ fluid overpressure generated by chemical reactions between a subducting slab and the mantle, according to field and microstructural observations of a shear zone.

The Role of Metamorphic Fluid in Tectonic Tremor Along the Alpine Fault, New Zealand
Geophysical Research Letters, 2021 Abstract The production of H 2 O during metamorphism along active plate boundaries is inferred to contribute to low‐frequency tectonic tremor. This study combines predictions from phase equilibria and mechanical modeling of coincident volume changes to investigate links of ...

Tidal Sensitivity of Tectonic Tremors in Nankai and Cascadia Subduction Zones [PDF]
Journal of Geophysical Research: Solid Earth, 2015 Abstract Tectonic tremors in subduction zones, which result from slip at the deep plate interface, are known to exhibit a 12.4 h periodicity in their activity, due to tidal influence. Because tidal stress can be calculated quantitatively, the response of the plate interface can yield quantitative information about

Role of plate convergence rate in shaping earthquake recurrence in subduction zones [PDF]
Scientific ReportsUnderstanding the complex interplay of subduction zone processes is key to unravelling the timing and distribution of great earthquake cycles within the framework of the plate tectonics paradigm.

Event Size Distribution of Shallow Tectonic Tremor in the Nankai Trough [PDF]
Geophysical Research Letters, 2019 AbstractSlow earthquake size distributions have been found to follow either a power law or an exponential law, depending on the data set. We investigated the size distribution of shallow tectonic tremor events along the Nankai trough, southwestern Japan, observed in 2009, 2015, 2016, and 2018 and estimated the seismic energy radiated during the events ...

Using Tectonic Tremor to Constrain Seismic Wave Attenuation in Cascadia [PDF]
Geophysical Research Letters, 2018 AbstractTectonic tremor can be used to constrain seismic wave attenuation for use in ground motion prediction equations in regions where moderately sized earthquakes occur infrequently. Here we quantify seismic wave attenuation by inverting tremor ground motion amplitudes in different frequency bands of interest, to determine frequency dependence of ...

Crustal Anisotropy From Tectonic Tremor in Guerrero, Mexico
Geochemistry, Geophysics, Geosystems, 2016 AbstractWe present new shear wave anisotropy measurements in the continental crust in northern Guerrero obtained from tectonic tremor. Measurements of crustal anisotropy had not been performed in this area due to the lack of seismicity. However, tectonic tremor activity is abundant and offers an opportunity to determine anisotropy parameters ...
