SEJSMICZNOŚĆ, TRZĘSIENIA ZIEMI I LINGWISTYKA [PDF]
Przegląd Geofizyczny, 2023 The general mechanism of earthquakes has been known for over a hundred years. The stresses accumulated over the years around the fault – the effect of tectonic plates movement relative to each other and deforming – must be released from time to time by ...

Very Low Frequency Earthquakes in Between the Seismogenic and Tremor Zones in Cascadia?
AGU Advances, 2022 Megathrust earthquakes and their associated tsunamis cause some of the worst natural disasters. In addition to earthquakes, a wide range of slip behaviors are present at subduction zones, including slow earthquakes that span multiple orders of spatial ...

Integrated rupture mechanics for slow slip events and earthquakes
Nature Communications, 2022 A new model elucidates the connections between silent earthquakes ("slow slip events") and regular ones by accounting for their finite rupture depth. It reconciles debated features of slow slip events and explains how they might lead to earthquakes.

Geophysical Research Letters, 2023 The discovery of slow earthquakes illuminates the existence of a strange depth dependence of seismogenesis, which contradicts the common understanding of smooth brittle/seismic‐ductile/aseismic transition as going deeper into the earth's surface layers ...

Slow earthquakes and low frequency tremor along the Apennines, Italy
Annals of Geophysics, 2008 This paper reviews the main observations on slow earthquakes and low frequency tremor made along the Apennines, the main seismic active zone of Italy. These observations have been made using a geodetic interferometer system operating since 1994

Ocean-bottom and surface seismometers reveal continuous glacial tremor and slip
Nature Communications, 2021 Anomalously slow earthquakes play a critical role in the earthquake cycle and fault sliding. Here, the authors detect continuous seismic radiation from a glacier sliding over its bed and show persistent coastal shaking to represent an addition to the ...

Bridging the gap between low-frequency and very-low-frequency earthquakes
Earth, Planets and Space, 2020 Slow earthquakes that are observed in the > 1 Hz frequency band are called tectonic tremor or low-frequency earthquakes (LFEs) and those in the 0.01–0.10 Hz band are called very-low-frequency earthquakes (VLFEs).

Frictional Mechanics of Slow Earthquakes [PDF]
Journal of Geophysical Research: Solid Earth, 2018 AbstractTectonic faults slip in a wide range of modes that span from slow slip events to dynamic rupture. A growing body of observations document this spectrum of failure modes in many geologic settings. However, the physical mechanisms that dictate slow slip are not understood.

Slow deformation event between large intraslab earthquakes at the Tonga Trench
Scientific Reports, 2021 Slow deformations associated with a subducting slab can affect quasi-static displacements and seismicity over a wide range of depths. Here, we analyse the seismotectonic activities in the Tonga subduction zone, which is the world’s most active area with ...

The slow self-arresting nature of low-frequency earthquakes
Nature Communications, 2021 Low-frequency earthquakes are a series of small earthquakes with lower dominant frequencies than ordinary earthquakes. By comparing the simulated earthquakes with the real data, we find that low-frequency earthquakes represent an earthquake rupture ...
