Anyone has arachnophobia? Damn, I am not afraid of spiders but it is still sending shivers up my spine.

Since orcas are a threat to their calves, maybe they’re trying to starve them to death or at least make them hunt somewhere away from where the whales roam. Might sound too complex a concept than they’re capable of, but animal intelligence keeps surprising me.

Aurora borealis is supposed to be spectacular tonight, I wish I wasn’t in the city. Still hoping to catch a glimpse, snow squalls right now but clearing later.

Abstract
With over a century since the last major rupture affecting the wider Los Angeles region, tectonic stress has steadily built along the southern San Andreas and San Jacinto fault systems, raising concerns of an imminent large earthquake. Cajon Pass, located at the junction of these faults, represents a critical site for potential through-going ruptures in Southern California. We constructed new 4D earthquake cycle simulations using a 1000-year paleoseismic rupture history of the San Andreas Fault System (SAFS) to assess spatial and temporal variations in stress. A semi-analytic Fourier transform model was used to compute stress from 3D dislocations in an elastic plate overlying a Maxwell viscoelastic half-space, assuming a complete coseismic reset of resolved shear stress on ruptured elements. Results show highest stress accumulation north of Cajon Pass (∼1.8 MPa/100 years) due to greater slip rates, and lower rates south of Cajon Pass (∼1.0–1.5 MPa/100 years). By 2025, Coulomb stress is estimated at 2.8 MPa on the Mojave South (MOS) segment, 1.8 MPa on the North San Bernardino (NSB1) segment and 3.6 MPa on the San Jacinto Bernardino (SJB) segment. Segments accumulate stresses with characteristic ranges of pre-event stress interpreted as failure thresholds: 1.2–2.7 MPa for MOS, 0.4–1.6 MPa for NSB1, and 1.2–2.9 MPa for SJB. When the stress disparity between segments SJB and MOS narrows, the faults appear to rupture jointly, suggesting that stress levels may control how Cajon Pass acts as an earthquake gate. These results may inform seismic hazard assessments by linking stress evolution to fault interactions.

Plain Language Summary
Southern California’s San Andreas and San Jacinto faults have not produced a major earthquake near Los Angeles in over a century. During that time, tectonic stress has continued to build along these faults, increasing the likelihood of a large future rupture. One key area of concern is Cajon Pass, where the two fault systems meet and could potentially rupture together. To investigate this, we used computer simulations of the last 1000 years of large earthquake activity to estimate how stress builds up on fault segments and affects neighboring segments over time. The model shows that stress has now reached high levels across the region and that the two fault systems may interact when their stress levels become similar. This suggests that Cajon Pass could act as an “earthquake gate” which sometimes blocks and other times allows large ruptures to propagate between faults. These results improve our understanding of earthquake interactions in Southern California and help refine regional hazard assessments.
