Satellite thermal infrared anomalies associatedwith strong earthquakes in the Vrancea area ofRomania

Open Geosciences, 2015
Thermal anomalies which are known to be significantprecursors of strong earthquakes can be evidencedby spectral thermal infrared (TIR) bands recordedby sensors on board of NOAA-AVHRR and Terra/Aqua-MODIS satellite.

Magnitude dependence of radiated energy spectra: Far‐field expressions of slip pulses in earthquake models [PDF]

Journal of Geophysical Research: Solid Earth, 2003
We examine the radiated waves emitted by events on a model fault. The model deterministically produces a complex sequence of events, with a wide range of sizes, from a uniform frictional instability. The spontaneous rupture events emit a rich spectrum of radiated waves as they nucleate, propagate, and decelerate within the complex stress field left by ...

Geometric barriers impacted rupture processes and stress releases of the 2023 Kahramanmaraş, Türkiye, earthquake doublet

Communications Earth & Environment
The 2023 Türkiye earthquake doublet, which includes two M W > 7.5 events, was the most devastating earthquake sequence globally over the past decade. Here we investigate the fault segmentations, rupture processes, radiated energy and stress releases of ...

Frictional Heating Processes and Energy Budget During Laboratory Earthquakes

, 2018
International audienceDuring an earthquake, part of the released elastic strain energy is dissipated within the slip zone by frictional and fracturing processes, the rest being radiated away via elastic waves. While frictional heating plays a key role in

“Lab‐Quakes”: Quantifying the Complete Energy Budget of High‐Pressure Laboratory Failure

AGU Advances
Understanding the interplay of various energy sinks during seismic fault slip is essential for advancing earthquake physics and improving hazard assessment. However, quantifying the energy consumed by major dissipative processes remains a challenge.

A method for mapping apparent stress and energy radiation applied to the 1994 Northridge Earthquake Fault Zone

Geophysical Research Letters, 2000
Using the Northridge earthquake as an example, we demonstrate a new technique able to resolve apparent stress within subfaults of a larger fault plane. From the model of Wald et al.

Seismic evidence for thermal runaway during intermediate-depth earthquake rupture [PDF]

, 2013
Intermediate-depth earthquakes occur at depths where temperatures and pressures exceed those at which brittle failure is expected. There are two leading candidates for the physical mechanism behind these earthquakes: dehydration embrittlement and self ...

Chiral Ratio of the Compressional and Shear Velocity for the Determination of Strong Earthquake Magnitudes through High-Frequency Energy Radiation

, 2015
In this short paper, we define and determine the connection between an electromagnetic chiral theory and the Hara’s relation (high-frequency energy radiation from the arrival time of a P-wave) under a chiral approach, considering the possibility that ...

Fracture mechanics of volcanic eruptions [PDF]

, 2009
Seismology is a key tool in the forecasting of volcanic eruptions. The onset of an eruption is often preceded and accompanied by an increase in local seismic activity, driven by fracturing within the edifice.
