Irregular Recurrence of Large Earthquakes Along the San Andreas Fault: Evidence from Trees

  author={Gordon C. Jacoby and Paul R. Sheppard and Kerry Sieh},
  pages={196 - 199}
Old trees growing along the San Andreas fault near Wrightwood, California, record in their annual ring-width patterns the effects of a major earthquake in the fall or winter of 1812 to 1813. Paleoseismic data and historical information indicate that this event was the "San Juan Capistrano" earthquake of 8 December 1812, with a magnitude of 7.5. The discovery that at least 12 kilometers of the Mojave segment of the San Andreas fault ruptured in 1812, only 44 years before the great January 1857… 

A 100-Year Average Recurrence Interval for the San Andreas Fault at Wrightwood, California

Evidence for five large earthquakes during the past five centuries along the San Andreas fault zone 70 kilometers northeast of Los Angeles, California, indicates that the average recurrence interval

Paleoearthquakes at Frazier Mountain, California delimit extent and frequency of past San Andreas Fault ruptures along 1857 trace

Large earthquakes are infrequent along a single fault, and therefore historic, well‐characterized earthquakes exert a strong influence on fault behavior models. This is true of the 1857 Fort Tejon

Triggering of 1812 Santa Barbara Earthquake by a Great San Andreas Shock: Implications for future seismic hazards in southern California

We study the evolution of the stress field over the last 200 years in southern California using the stress buildup associated with major faults and stress drops associated with great earthquakes. In

Behavior of the southernmost San Andreas Fault during the past 300 years

Surficial creep occurs at low rates along the Coachella Valley segment of the San Andreas fault, which has not produced a large earthquake during the period of historical record. Geodetic data

Evidence for Large Earthquakes on the San Andreas Fault at the Wrightwood, California, Paleoseismic Site: a.d. 500 to Present

We present structural and stratigraphic evidence from a paleoseismic site near Wrightwood, California, for 14 large earthquakes that occurred on the southern San Andreas fault during the past 1500

A case for historic joint rupture of the San Andreas and San Jacinto faults

This work uses dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to suggest that this has likely occurred in the historic past.

San Andreas Fault Zone, California: M ≥5.5 Earthquake History

The San Andreas fault zone has been a very significant source of major California earthquakes. From 1812 to 1906 it generated four major earthquakes of M ∼7 or larger in two pairs on two major

Change in Failure Stress on the Southern San Andreas Fault System Caused by the 1992 Magnitude = 7.4 Landers Earthquake

The 28 June Landers earthquake brought the San Andreas fault significantly closer to failure near San Bernardino, a site that has not sustained a large shock since 1812, and stress on theSan Andreas north of Los Angeles dropped, potentially delaying the next great earthquake there by 2 to 10 years.

A Maximum Rupture Model for the Southern San Andreas and San Jacinto Faults, California, Derived From Paleoseismic Earthquake Ages: Observations and Limitations

Paleoseismic rupture histories provide spatiotemporal models of earthquake moment release needed to test numerical models and lengthen the instrumental catalog. We develop a model of the fewest and

Ages of Late Holocene earthquakes on the central Garlock fault near El Paso Peaks, California

A trench across the central Garlock fault within a small playa adjacent to El Paso Mountains revealed buried fissures and fault scarps that provide strong evidence for five surface rupturing



Holocene rate of slip and tentative recurrence interval for large earthquakes on the San Andreas fault, Cajon Pass, southern California

Abstract Detailed mapping of the San Andreas fault zone where it crosses Cajon Creek, southern California, has revealed a number of late Quaternary deposits and geomorphological features offset by

Surface faulting associated with major earthquakes commonly kills, damages, or otherwise disturbs the growth of trees along the fault trace. Because severe disturbances are reflected in the annual

Seasonal Course of Photosynthesis, Respiration, and Distribution of C in Young Pinus resinosa Trees as Related to Wood Formation.

The results indicate that the production of thick-walled xylem tracheids normally associated with latewood is physiologically correlated with maturation of the current season's needles, and a sharply increased amount of photosynthate becomes available for wall synthesis by cambial derivatives.

Isolation and characterization of a novel protein (X-ORF product) from SIV and HIV-2.

The X-ORF is proven to be a new retroviral gene that contains a substantial quantity of a viral protein that is not a product of the gag, pro, pol, or env genes and will distinguish between HIV-1 and HIV-2.
