Article
Northwest directed slip from the southern San Andreas Fault is transferred to the Mission Creek, Banning, and Garnet Hill fault strands in the northwestern Coachella Valley. How slip is partitioned between these three faults is critical to southern California seismic hazard estimates, but is poorly understood. In this paper, we report the first sli...

The 4 April 2010 moment magnitude (M_w) 7.2 El Mayor–Cucapah earthquake revealed the existence of a previously unidentified fault system in Mexico that extends ∼120 km from the northern tip of the Gulf of California to the U.S.–Mexico border. The system strikes northwest and is composed of at least seven major faults linked by numerous smaller faul...

This fieldtrip will explore the 4D architecture of an oblique rift margin, set within the Big Bend domain of the San Andreas fault system. We will visit and explore the surface ruptures from the 2010 El Mayor-Cucapah and 1892 Laguna Salada earthquakes, along with their interactions, to see spectacular field relations that show how fault systems wor...
Article
As an alternative to grid-based approaches, point-based computing offers access to the full information stored in unstructured point clouds derived from lidar scans of terrain. By employing appropriate hierarchical data structures and algorithms for out-of-core processing and view-dependent rendering, it is feasible to visualize and analyze three-d...
Article
Three-dimensional (3D) slip vectors recorded by displaced landforms are difficult to constrain across complex fault zones and the uncertainties associated with such measurements become increasingly challenging to assess as landforms degrade over time. We approach this problem from a remote sensing perspective by using terrestrial laser scanning (TL...
Article
Full-text available
Large [moment magnitude (Mw) ≥ 7] continental earthquakes often generate complex, multifault ruptures linked by enigmatic zones of distributed deformation. Here, we report the collection and results of a high-resolution (≥nine returns per square meter) airborne light detection and ranging (LIDAR) topographic survey of the 2010 Mw 7.2 El Mayor–Cucap...
Conference Paper
Full-text available
The Mw 7.2 El Mayor-Cucapah earthquake revealed the existence of a previously unidentified plate-margin fault system that extends 120 km from the northern tip of the Gulf of California to the international border. The system is composed of at least 6 major faults linked by numerous smaller faults. We observed that localized kinematics on individual...
Article
We analyze the modification of fault scarps formed by the 4 April 2010 M 7.2 El Mayor-Cucapah earthquake through comparison of terrestrial LiDAR scans acquired within two weeks of the event to repeat scans one year later. From this comparison of annual scans we assess the mechanisms and rates of scarp modification in different substrates, and attem...
Article
We assess the slip distribution at four sites along the 4 April 2010 El Mayor-Cucapah (EMC) earthquake surface rupture in northern Baja-California with cm-resolution terrestrial lidar (TLS). Slip distributions based on field measurements typically show abrupt variation (0.5-2 m) over short along-strike distances (10 to 100 m), implying large along-...
Article
Virtual globes are becoming ubiquitous in the visualization of planetary bodies and Earth specifically. While many of the current virtual globes have proven to be quite useful for remote geologic investigation, they were never designed for the purpose of serving as virtual geologic instruments. Their shortcomings have become more obvious as earth s...
Article
We report newly available data sets and preliminary analysis of ground- and airborne-lidar surveys of the 4 April 2010 El Mayor-Cucapah earthquake rupture. The hyperarid setting and varied surficial geology of this complex rupture zone presents an ideal setting to advance the use of lidar in post-earthquake scientific response. Terrestrial lidar su...
Article
High-resolution terrestrial LiDAR (t-LiDAR) datasets collected 12-18 days after the 4 April 2010, Mw7.2 El Mayor-Cucapah earthquake in northern Mexico demonstrate the capability of t-LiDAR to rapidly quantify and preserve details of coseismic surface deformation at high resolution. Though the quantity of equipment required even for highly portable...
Article
Virtual globes are becoming ubiquitous for visualizing the Earth and other planets. However, as earth scientists pursue methods to visually explore and interpret earth surface processes using sub-meter pixel resolution digital elevation models (DEM) and imagery data spanning large areas, limitations of the commonly used virtual globes have emerged....
Article
Measurements derived from high-resolution terrestrial LiDAR (t-Lidar) surveys of landforms displaced during the 16 December 1954 Mw 6.8 Dixie Valley earthquake in central Nevada confirm the absence of historical strike slip north of latitude 39.5°N. This conclusion has implications for the effect of stress changes on the spatial and temporal evolut...
Article
Ground-based LiDAR (Light Detection and Ranging) survey techniques are enabling remote visualization and quantitative analysis of geologic features at unprecedented levels of detail. For example, digital terrain models computed from LiDAR data have been used to measure displaced landforms along active faults and to quantify fault-surface roughness....
Article
High resolution topographic measurements form the basis for slip-rate studies along active fault systems. However, meter-scale features such as fault scarps or offset terrace risers are insufficiently resolved on available remotely-sensed digital elevation models (e.g., 10 m NED), rendering it necessary to make field- based topographic measurements...
Article
As terrestrial LiDAR scanning systems become increasingly available, strategies for executing efficient field surveys in settings without access to the power grid are increasingly needed. To evaluate scan methods and develop an off-grid power system, we used a tripod-mounted laser scanner to create high resolution (≤40 mm point spacing) topographic...
