Prevalence of aseismic slip linking fluid injection to natural and anthropogenic seismic swarms

P Danré, L De Barros, F Cappa… - Journal of Geophysical …, 2022 - Wiley Online Library
Anthropogenic fluid injections at depth induce seismicity which is generally organized as
swarms, clustered in time and space, with moderate magnitudes. Earthquake swarms also …

Updip Fluid Flow in the Crust of the Northeastern Noto Peninsula, Japan, Triggered the 2023 Mw 6.2 Suzu Earthquake During Swarm Activity

K Yoshida, N Uchida, Y Matsumoto… - Geophysical …, 2023 - Wiley Online Library
An Mw 6.2 earthquake occurred in Suzu, northeastern Noto Peninsula, Japan, on 5 May

Dual seismic migration velocities in seismic swarms

P Dublanchet, L De Barros - Geophysical Research Letters, 2021 - Wiley Online Library
Fluid‐induced earthquake sequences generally appear as expanding swarms activating a
particular fault. The recent analysis of a swarm in the Corinth rift has revealed a dual …

Hypocenter migration and seismicity pattern change in the Yamagata‐Fukushima border, NE Japan, caused by fluid movement and pore pressure variation

K Yoshida, A Hasegawa - Journal of Geophysical Research …, 2018 - Wiley Online Library

were investigated in details for events in the Yamagata‐Fukushima border earthquake …

Slab-derived fluid storage in the crust elucidated by earthquake swarm

Y Mukuhira, M Uno, K Yoshida - Communications Earth & Environment, 2022 - nature.com
Slab-derived fluids control crustal dynamics in the subduction zone. However, the slab-
derived fluid budget has never been quantified beyond a geophysical and geological …

The growth of earthquake clusters

T Fischer, S Hainzl - Frontiers in Earth Science, 2021 - frontiersin.org
Migration of hypocenters is a common attribute of induced injection seismicity and of
earthquake swarms, which distinguishes them from aftershock sequences. Spreading of the …
