Observations of stress relaxation before earthquakes [PDF]

, 2004
Theory and observations suggest that seismic shear wave splitting, caused by fluid-saturated stress-aligned microcracks, directly monitors low-level deformation before fracturing, faulting and earthquakes occur.

Earthquake swarms on transform faults [PDF]

Geophysical Journal International, 2009
SUMMARY Swarm-like earthquake sequences are commonly observed in a diverse range of geological settings including volcanic and geothermal regions as well as along transform plate boundaries. They typically lack a clear mainshock, cover an unusually large spatial area relative to their total seismic moment release, and fail to decay in time according to

Time variations in the chemical and isotopic composition of fumarolic gases at Hakone volcano, Honshu Island, Japan, over the earthquake swarm and eruption in 2015, interpreted by magma sealing model

Earth, Planets and Space, 2019
Definite increases in the components ratios of CO2/H2O, CO2/H2S, CO2/CH4 and He/CH4 were observed at the fumarolic gases from Owakudani geothermal area located at the center of Hakone volcanic caldera (Honshu Island, Japan), synchronized with the ...

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

Communications Earth & Environment, 2022
The volume of slab-derived fluid which resulted in the earthquake swarm associated with the 2011 Mw 9.1 Tohoku earthquake is quantified by comparison of injection-induced seismicity with geological proxies.

The 2010 MW 6.8 Yushu (Qinghai, China) earthquake: constraints provided by InSAR and body wave seismology [PDF]

, 2011
By combining observations from satellite radar, body wave seismology and optical imagery, we have determined the fault segmentation and sequence of ruptures for the 2010 Mw 6.8 Yushu (China) earthquake. We have mapped the fault trace using displacements

Hydrogeochemical characteristics and genesis of Hongshuilantang Hot Spring and its water temperature anomalies during the Rushan earthquake swarm in Eastern China

Frontiers in Earth Science, 2023
Water temperatures of hot springs close to tectonic fault zones often show some variations before earthquakes, and analyses of earthquake precursors in hot springs have significant referential meaning for earthquake monitoring and forecasting. This study

Storytelling, language, and the earthquake swarm of May 2018: Insights into Shimaore and Kibushi from narrative analysis

Comptes Rendus. Géoscience, 2022
The earthquake swarm that struck Mayotte in 2018 incited panic and various reactions among the local population. Because earthquakes are rare on the island, people were beside themselves, with many leaving their homes to wait out the night under the open

Swarm Satellite Magnetic Field Data Analysis Prior to 2019 Mw = 7.1 Ridgecrest (California, USA) Earthquake

Geosciences, 2020
This work presents an analysis of the ESA Swarm satellite magnetic data preceding the Mw = 7.1 California Ridgecrest earthquake that occurred on 6 July 2019. In detail, we show the main results of a procedure that investigates the track-by-track residual
