The horizontal displacements accompanying the 1906 San Francisco earthquake and the 1989 Loma Prieta earthquake are computed from geodetic survey measurements. The 1906 earthquake displacement field is entirely consistent with right-lateral strike slip on the San Andreas fault. In contrast, the 1989 Loma Prieta earthquake exhibited subequal components of strike slip and reverse faulting. This result, together with other seismic and geologic data, may indicate that the two earthquakes occurred… 
Coseismic sediment deformation during the 1989 Loma Prieta earthquake
[1] Inelastic horizontal sediment deformation from the MS 7.1, 17 October 1989 Loma Prieta earthquake has been estimated to be on the order of 20 cm at a site in Gilroy, California, about 32 km east
Earthquake travel time tomography of the southern Santa Cruz Mountains: Control of fault rupture by lithological heterogeneity of the San Andreas Fault Zone
The 1989 Loma Prieta earthquake occurred along the stretch of the San Andreas fault zone within the southern Santa Cruz Mountains that last failed as a major earthquake in 1906. The southeastern end
Forecasts of the 1989 Loma Prieta, California, earthquake
Abstract The magnitude ( M w ) 6.9 Loma Prieta earthquake struck the San Francisco Bay area of central California at 5:04 p.m. local time on 17 October 1989, killing 62 people and generating billions
Re-evaluation of 1906 surface faulting, geomorphic expression, and seismic hazard along the San Andres fault in the Southern Santa Cruz mountains
The lack of through-going, right-lateral surface rupture accompanying the Loma Prieta earthquake has raised questions about the behavior of the San Andreas fault in the southern Santa Cruz Mountains.
Long-term uplift of the Santa Cruz coastline in response to repeated earthquakes along the San Andreas fault
Abstract The 18 October 1989 Loma Prieta earthquake ( M S 7.1) provides unprecedented insights into geomorphological processes of the Santa Cruz Mountains region of central California. In particular,
Horizontal deformation associated with the Loma Prieta earthquake
Co-seismic horizontal displacements for the 1989 Loma Prieta earthquake were derived from preseismic triangulation/trilateration observations and post-seismic GPS observations. As part of this
Coseismic deformation of the Wrights tunnel during the 1906 San Francisco earthquake: A key to understanding 1906 fault slip and 1989 surface ruptures in the southern Santa Cruz Mountains, California
The Wrights tunnel is an abandoned railroad tunnel that crosses the San Andreas fault in the southern Santa Cruz Mountains in the vicinity of the 1989 Loma Prieta earthquake. The tunnel was damaged
High tsunami frequency as a result of combined strike-slip faulting and coastal landslides
The 12 January 2010 Mw 7.0 Haiti earthquake exhibited primarily strike-slip motion but unusually generated a tsunami. An extensive field survey reveals that coastal strike-slip fault systems produce
Slip in the 1868 Hayward earthquake from the analysis of historical triangulation data
Despite the importance of the Hayward fault for earthquake hazards in the San Francisco Bay area, neither the rupture length nor the average coseismic slip in the most recent major earthquake, which
Source study of the 1906 San Francisco earthquake
All quality teleseismic recordings of the great 1906 San Francisco earthquake archived in the 1908 Carnegie Report by the State Earthquake Investigation Commission were scanned and digitized. First


Geodetic estimate of coseismic slip during the 1989 Loma Prieta, California, Earthquake
Offsets in the relative positions of geodetic stations resulting from the Loma Prieta earthquake can be explained with a dislocation model that includes buried oblique slip on a rupture surface
Evolution of the Northern Santa Cruz Mountains by Advection of Crust Past a San Andreas Fault Bend
The late Quaternary marine terraces near Santa Cruz, California, reflect uplift associated with the nearby restraining bend on the San Andreas fault, which can account for the general topography of the northern Santa Cruz Mountains.
Teleseismic and near-field analysis of the Nahanni earthquakes in the northwest territories, Canada
The analysis of the Nahanni earthquakes of October 5, 1985 ( MS 6.6), and December 23, 1985 ( MS 6.9), will have important implications for the assessment of seismic hazards in intraplate
An analysis of the 1985 Nahanni earthquakes
Abstract Two large magnitude earthquakes occurred in 1985 near the North Nahanni River in the northeast Cordillera, Northwest Territories, Canada, on 5 October ( M S 6.6) and 23 December ( M S 6.9).
Geodetic measurement of deformation in the Loma Prieta, California Earthquake with very long baseline interferometry
Following the Loma Prieta earthquake, two mobile Very Long Baseline Interferometry (VLBI) systems operated by the NASA Crustal Dynamics Project and the NOAA National Geodetic Survey were deployed at
Holocene activity of the San Andreas fault at Wallace Creek
Wallace Creek is an ephemeral stream in central California, the present channel of which displays an offset of 128 m along the San Andreas fault. Geological investigations have elucidated the
Form, genesis, and deformation of central California wave-cut platforms
Modern and ancient wave-cut platforms on Ben Lomond Mountain in central California are broadly similar in shape. They have a seaward slope composed of two segments: a steeper, slightly concave
Modification of wave-cut and faulting-controlled landforms
From a casual observation that the form of degraded fault scarps resembles the error function, this investigation proceeds through an elementary diffusion equation representation of landform
Eruption of basalt and andesite lava degasses 222Rn and 210Po
Activities of 222Rn and 210Po were measured in a September, 1983, basic andesite lava from Arenal and a November, 1983, basalt from Kilauea, starting 3 and 1 days after eruption, respectively. In
