Seismic velocity changes and nonvolcanic tremor activity in the Parkfield area in California reveal that large earthquakes induce long-term perturbations of crustal properties in the San Andreas fault zone. The 2003 San Simeon and 2004 Parkfield earthquakes both reduced seismic velocities that were measured from correlations of the ambient seismic noise and induced an increased nonvolcanic tremor activity along the San Andreas fault. After the Parkfield earthquake, velocity reduction and…

Seismic evidence of fluid migration in northeastern Japan after the 2011 Tohoku-Oki earthquake
Detecting remotely triggered temporal changes around the Parkfield section of the San Andreas fault
Detecting temporal changes in fault zone properties at seismogenic depth have been a long-sought goal in the seismological community for many decades. Recent studies based on waveform analysis of…
Nonvolcanic Tremor Evolution and the San Simeon and Parkfield, California, Earthquakes
TLDR
Monitoring of the San Andreas Fault in the Parkfield, California, region revealed that after two strong earthquakes, tremor activity increased in a nearly dormant tremor zone, increased and became periodic in a previously active zone, and has remained elevated and periodic for over 4 years.
Tremor-tide correlations and near-lithostatic pore pressure on the deep San Andreas fault
TLDR
A robust correlation is identified between extremely small, tidally induced shear stress parallel to the San Andreas fault and non-volcanic tremor activity near Parkfield, California, suggesting that this tremor represents shear failure on a critically stressed fault in the presence of near-lithostatic pore pressure.
Fact or friction: Inferring rheology from nonvolcanic tremor and low-frequency earthquakes on the deep San Andreas fault
Here I present results from a collection of three papers that document the response of deep non-volcanic tremor and constituent low-frequency earthquakes to stress perturbations from the Earth tides.…
Seismic velocity decrease and recovery related to earthquake swarms in a geothermal area

Investigation of coseismic and postseismic processes using in situ measurements of seismic velocity variations in an underground mine
The in situ mechanical response of a rock mass to a sudden dynamic and static stress change is still poorly known. To tackle this question, we conducted an experiment in an underground mine to…
Coseismic Velocity Change in the Rupture Zone of the 2008 Mw 7.9 Wenchuan Earthquake Observed from Ambient Seismic Noise

Spatial and temporal seismic velocity changes on Kyushu Island during the 2016 Kumamoto earthquake
TLDR
The largest seismic velocity reduction observed at Aso volcano during the earthquake was likely caused by pressurized volcanic fluids, and the large increase in seismic velocity at the volcano’s magma body observed ~3 months after the earthquake may have been a response to depressurization caused by the eruption.

Preseismic velocity changes observed from active source monitoring at the Parkfield SAFOD drill site
TLDR
It is shown that stress changes are indeed measurable using this technique, and an excellent anti-correlation between changes in the time required for a shear wave to travel through the rock along a fixed pathway and variations in barometric pressure is observed.

TLDR
Nonvolcanic tremor activity is discovered within a transform plate boundary zone along the San Andreas Fault near Cholame, California, the inferred epicentral region of the 1857 Fort Tejon earthquake.
