Fast and full characterization of large earthquakes from prompt elastogravity signals
Autor: Kévin Juhel, Quentin Bletery, Andrea Licciardi, Martin Vallée, Céline Hourcade, Théodore Michel
Publikováno v: Communications Earth & Environment, Vol 5, Iss 1, Pp 1-8 (2024)
Abstract Prompt ElastoGravity Signals are light-speed gravity-induced signals recorded before the arrival of seismic waves. They have raised interest for early warning applications but their weak amplitudes close to the background seismic noise have

Publikováno v: Earth, Planets and Space, Vol 71, Iss 1, Pp 1-6 (2019)
Abstract A recent work by Kimura et al. (Earth Planets Space 71:27, 2019. https://doi.org/10.1186/s40623-019-1006-x) (hereafter referred to as K19) claims to provide the first observational constraints on the prompt elastogravity signals (PEGS) induc

Rapid source characterization of the Maule earthquake using Prompt Elasto-Gravity Signals
Autor: Gabriela Arias Mendez, Quentin Bletery, Andrea Licciardi, Kévin Juhel, Jean-Paul Ampuero, Bertrand Rouet-Leduc
The recently identified Prompt Elasto-Gravity Signals (PEGS), generated by large earthquakes, propagate at the speed of light and are sensitive to the earthquake magnitude and focal mechanism. These characteristics make PEGS potentially very advantag

Prompt gravity signal induced by the 2011 Tohoku-Oki earthquake
Autor: Jean-Paul Montagner, Kévin Juhel, Matteo Barsuglia, Jean Paul Ampuero, Eric Chassande-Mottin, Jan Harms, Bernard Whiting, Pascal Bernard, Eric Clévédé, Philippe Lognonné
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-7 (2016)
Earthquakes have been theorised to produce gravity signals that may arrive before seismic waves, but until now they had not been detected. Montagneret al. have detected prompt gravity signals from the 2011 Tohoku-Oki earthquake thus allowing an early

Early earthquake detection capabilities of different types of future-generation gravity gradiometers
Autor: Jean-Paul Montagner, Kévin Juhel, Jean-Paul Ampuero, T. Shimoda, M. Barsuglia
Publikováno v: Geophysical Journal International
Geophysical Journal International, 2021, 224 (1), pp.533-542. ⟨10.1093/gji/ggaa486⟩
SUMMARY Since gravity changes propagate at the speed of light, gravity perturbations induced by earthquake deformation have the potential to enable faster alerts than the current earthquake early warning systems based on seismic waves. Additionally,

Timeliness of earthquake magnitude estimation from the prompt elasto-gravity signal using Deep Learning
Autor: Jean-Paul Ampuero, Quentin Bletery, Andrea Licciardi, Bertrand Rouet-Leduc, Kévin Juhel
Mass redistribution during large earthquakes produces a prompt elasto-gravity signal (PEGS) that travels at the speed of light and can be observed on seismograms before the arrival of P-waves. PEGS carries information about earthquake magnitude and t

International audience; As soon as an earthquake starts, the rupture and the propagation of seismic waves redistribute masses within the Earth. This mass redistribution generates in turn a long-range perturbation of the Earth gravitational field, whi
