Seasonal rain and snow trigger small quakes on California faults（图）
Seasonal rain snow small quakes California faults
2017/7/21
California’s winter rains and snow depress the Sierra Nevada and Coast Ranges, which then rebound during the summer, changing the stress on the state’s earthquake faults and causing seasonal upticks i...
This paper presents an overview of the advancement in our knowledge of California's earthquake history since
~ 1800, and especially during the last 30 years. We first review the basic statewide resea...
Re-Thinking Southern California Earthquake Scenarios in Coachella Valley Segment of San Andreas Fault
Southern California Earthquake Scenarios Coachella Valley Segment San Andreas Fault
2014/12/30
AMHERST, Mass. – New three-dimensional (3D) numerical modeling that captures far more geometric complexity of an active fault segment in southern California than any other, suggests that the overall e...
Analysis of teleseismicPwaves with a 5200-station array in Long Beach, California: Evidence for an abrupt boundary to Inner Borderland rifting
Analysis of teleseismic waves in Long Beach, California Evidence an abrupt boundary Inner Borderland rifting
2014/4/10
We analyze teleseismicPwaves from four Mw≥6.5 earthquakes recorded by a petroleum industry survey in Long Beach, California. The survey used a 2-D array with up to 5200 seismometers, 120 m mean spacin...
Evidence of upper-mantle processes related to continental rifting versus oceanic crust in the Gulf of California
Mantle processes Phase transitions North America
2014/4/10
Receiver functions from teleseismic events, recorded by stations around the Gulf of California, are used to map the upper-mantle seismic discontinuities. We observe a mean transition zone thickness co...
High-resolution 3D shallow crustal structure in Long Beach, California: Application of ambient noise tomography on a dense seismic array
High-resolution 3D shallow crustal structure in Long Beach California ambient noise tomography on a dense seismic array
2014/4/10
Ambient noise tomography has proven to be effective in resolving shallow earth structure. We applied ambient noise tomography on a dense seismic array in Long Beach, California. The array was composed...
Sedimentary structure of large sand dunes: examples from Dumont and Eureka dunes, California
Ground penetrating radar Geomorphology Wave propagation
2014/4/10
The current research presents ground penetrating radar images up to 30 m in depth of two large desert dunes in California, USA— a barchanoid ridge in the Dumont field and a linear dune in the Eureka e...
The Relationship Between Upper Mantle Anisotropic Structures Beneath California, Transpression, and Absolute Plate Motions
The Relationship Between Upper Mantle Anisotropic Structures California Transpression Absolute Plate Motions
2014/4/10
We calculated SKS splitting parameters for the California Integrated Seismic Network. In southern California, we also estimated splitting in the upper 100 km using azimuthal anisotropy determined fr...
Superficial simplicity of the 2010 El Mayor–Cucapah earthquake of Baja California in Mexico
Superficial simplicity El Mayor–Cucapah earthquake Baja California in Mexico
2014/4/9
The geometry of faults is usually thought to be more complicated at the surface than at depth and to control the initiation, propagation and arrest of seismic ruptures 1–6. The fault system that runs ...
Travelling ionospheric disturbance over California mid 2000
Travelling ionospheric disturbance California mid 2000

In this paper, the GPS data collected by more than 130 permanent GPS stations that belong to the Southern California Integrated GPS Network (SCIGN) around the launch of a Minuteman-II missile on 8 Jul...
Small world in a seismic network:the California case
Small world seismic network California case
2009/10/30
Recent work has shown that disparate systems can be described as complex networks i.e. assemblies of nodes and links with nontrivial topological properties. Examples include technological, biological ...
Loading rates in California inferred from aftershocks
Loading rates California aftershocks
2009/10/30
We estimate the loading rate in southern California and the change in stress induced by a transient slip event across the San Andreas fault (SAF) system in central California, using a model of static ...
Evidence for superelevation, channel incision, and formation of cyclic steps by turbidity currents in Eel Canyon, California
Evidence for superelevation channel incision formation of cyclic steps turbidity currents Eel Canyon California
2014/4/8
We performed a multibeam survey of Eel Canyon, offshore northern California. The survey revealed a signifi cant bend in the canyon that appears to be due to the oblique compressional tectonics of the ...
Crustal thickness variations in the margins of the Gulf of California from receiver functions
Moho depth receiver functions lower crustal flow
2014/4/10
Receiver functions (RFs) from teleseismic events recorded by the NARS-Baja array were used to map crustal thickness in the continental margins of the Gulf of California, a newly forming ocean basin. A...
