An Intense Quantum of Deformation in the Deep Crust as Seen from Geomechanical Modeling in Southern California
AbstractA rapidly develo** high-amplitude shear deformation anomaly in the upper crustal interval (at depths of up to 10 km), the so-called...

Strain localization instabilities and the genesis of multiple axes of seafloor spreading in the Carmen basin, southern Gulf of California
We present new insight into the tectonic evolution of the Carmen basin (CB) in the southern Gulf of California (GC) from high-resolution bathymetry...

Occurrence Apparent Velocities for Identification and Quantification of Space–Time Clustering Precursory to a Large Earthquake. Application to Large (M > 7.0) Earthquakes in Southern California and Northern Baja California
Space–time seismic clusters, localized bursts of seismic activity, are a feature of background seismicity before the occurrence of large earthquakes,...

Estimation of the desert dust balance and its relationship with environmental factors in the southern Baja California Peninsula
The emission, transport, and deposition of desert dust are influenced by environmental factors evaluated mainly as a function of precipitation, air...

The 2019 Ridgecrest Large Earthquake in Southern California: Studying the Source Formation Based on Geomechanical Modelling
AbstractHere we present a simulation of the crust’s stress–strain state in the period prior to the 2019 Ridgecrest (M = 7.1) earthquake in Southern...

Little Ice Age flood events recorded in sag pond sediments in the Carrizo Plains National Monument, California
In California, severe precipitation events (SPEs) are often associated with winter season atmospheric rivers. These SPEs can generate hurricane-scale...

Lower crustal assimilation revealed by sulfur isotope systematics of the Bear Valley Intrusive Suite, southern Sierra Nevada Batholith, California, USA
The origin of the wide range of sulfur isotope compositions (i.e., δ 34 S) measured in arc rocks remains debated. While the observed δ 34 S variability...

Fusion of GNSS and InSAR time series using the improved STRE model: applications to the San Francisco Bay Area and Southern California
The spatio-temporal random effects (STRE) model is a classic dynamic filtering model, which can be used to fuse GNSS and InSAR deformation data. The...
