Radiation energy measured at earthquake source [PDF]
Geophysical Research Letters, 2005 We propose a new radiation energy, which is defined as an energy radiation measured close to the source. This energy enables us to rigorously handle the energy emitted not only from an earthquake but also from asperities of an earthquake. Therefore we can discuss a spatial variation of the radiation energy on the fault and compare it with the fracture ...

Nonlinear Radiation Damping: A New Method for Dissipating Energy in Dynamic Earthquake Rupture Simulations [PDF]
The Seismic Record, 2023 Dynamic earthquake rupture simulations are used to understand earthquake mechanics and the ground shaking that earthquakes produce. These simulations can help diagnose past earthquake behavior and are also used to generate scenarios of possible future ...

Dynamics, Radiation, and Overall Energy Budget of Earthquake Rupture With Coseismic Off‐Fault Damage [PDF]
Journal of Geophysical Research: Solid Earth, 2019 AbstractEarthquake ruptures dynamically activate coseismic off‐fault damage around fault cores. Systematic field observation efforts have shown the distribution of off‐fault damage around main faults, while numerical modeling using elastic‐plastic off‐fault material models have demonstrated the evolution of coseismic off‐fault damage during earthquake ...

Toy model of accumulation and radiation of strain energy driven by big data of earthquakes [PDF]
Journal of Physics Communications, 2021 AbstractWe propose the pointwise toy-model, which demonstrates the accumulation and radiation of the (seismic) strain-energy. The calculated absorbed-seismic-energy is mapped to the accumulated strain-energy to balance the radiated strain-energy, because the accumulation of the strain-energy is caused by the subduction of one plate below another plate ...

Energy radiation from intermediate‐ to large‐magnitude earthquakes: Implications for dynamic fault weakening [PDF]
Journal of Geophysical Research: Solid Earth, 2010 The amount of energy radiated from an earthquake can be measured using recent methods based on earthquake coda signals and spectral ratios. Such methods are not altered by either site or directivity effects, with the advantage of a greatly improved accuracy.

Statistical Analysis of High–Energy Particle Perturbations in the Radiation Belts Related to Strong Earthquakes Based on the CSES Observations [PDF]
Remote Sensing, 2023 Earthquakes (EQs) are a significant natural threat to humanity. In recent years, with advancements in space observation technology, it has been put forward that the electromagnetic effects of earthquakes can propagate into space in various ways, causing ...

Off-fault damage controls near-surface rupture behaviour in soft sediments [PDF]
Nature CommunicationsSurface-rupturing faults represent some of the most devastating examples of earthquake-related hazards. Near surface rupture behaviour is poorly understood, due to limited information concerning the amount of off-fault energy dissipated in a volume ...

The 2021 Mw8.1 Kermadec Megathrust Earthquake: An Event Rupturing the Slab‐Mantle Interface With Up‐Dip High‐Frequency Seismic Energy Radiation [PDF]
Geophysical Research LettersMegathrust earthquakes often break the slab‐crust interface and radiate high‐frequency seismic waves from the down dip of their coseismic slip. In contrast, we show that the 2021 Mw8.1 Kermadec earthquake deviates from this mode. We resolve the kinematic
