Revealing the spatiotemporal complexity of the magnitude distribution and b-value during an earthquake sequence

M Herrmann, E Piegari, W Marzocchi - Nature Communications, 2022 - nature.com
Abstract The Magnitude–Frequency-Distribution (MFD) of earthquakes is typically modeled
with the (tapered) Gutenberg–Richter relation. The main parameter of this relation, the b …

Data-driven spatiotemporal assessment of the event-size distribution of the Groningen extraction-induced seismicity catalogue

AG Muntendam-Bos, N Grobbe - Scientific Reports, 2022 - nature.com
For induced seismicity, the non-stationary, heterogeneous character of subsurface stress
perturbations can be a source of spatiotemporal variations in the scaling of event sizes; one …

Cascadia subduction zone fault heterogeneities from newly detected small magnitude earthquakes

EA Morton, SL Bilek, CA Rowe - Journal of Geophysical …, 2023 - Wiley Online Library
The Cascadia subduction zone (CSZ) is known to host M9 megathrust ruptures; however, no
such event has occurred in historical observation. The distribution and characteristics of …

Physics-informed deep learning to forecast M^ max during hydraulic fracturing

Z Li, DW Eaton, J Davidsen - Scientific Reports, 2023 - nature.com
Short-term forecasting of estimated maximum magnitude (M^ max) is crucial to mitigate risks
of induced seismicity during fluid stimulation. Most previous methods require real-time …

Anomalies and transient variations of b-value in Italy during the major earthquake sequences: what truth is there to this?

AM Lombardi - Geophysical Journal International, 2023 - academic.oup.com
SUMMARY The Gutenberg–Richter b-value is thought to be a proxy of stress conditions in
the crust and therefore able to locate asperities as zones of stress concentration responsible …
