These data are a summary of modeled exposure of various lifeline infrastructure linear features and facilities (transportation, water supply and wastewater, oil and gas, electric power, and telecommunications) to potential hazards resulting from the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. Existing hazard data (surface offset, ground shaking (mainshock and aftershocks), landslide, liquefaction, and fire following earthquake) were looked at alone and in combination with each other relative to the lifeline infrastructure linear features and facilities to provide estimates of potential exposure to various...

These data are a geospatial representation of potential moderate or high ground shaking intensity for seven M5 or greater aftershocks resulting from the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data take existing ground shaking data for the HayWired mainshock and seven aftershocks (M6.21 Palo Alto, M5.69 Palo Alto, M5.22 Palo Alto, M5.26 Palo Alto, M5.98 Mountain View, M6.40 Cupertino, and M5.35 Sunnyvale) and combine them into a single ground shaking intensity surface intended for estimating possible repeat exposure to moderate or high intensity ground shaking. This vector .SHP dataset was developed...

The dryland ecosystems of the western United States have been invaded by exotic annual grasses, such as cheatgrass (Bromus tectorum L.), that has promoted increased fire activity and reduced biodiversity detrimental to socio-environmental systems. The use of remote sensing tools to monitor exotic annual grass cover and dynamics over large areas can support early detection and rapid response initiatives. This dataset was generated using in situ observations from Bureau of Land Management's (BLM) Assessment, Inventory, and Monitoring data (AIM) plots, weekly composites of harmonized Landsat and Sentinel-2 (HLS) data, relevant environmental, vegetation, remotely sensed, and geophysical factors and machine learning...

This report summarizes the age-dating results from two alluvial fan surfaces (map units Qyf2 and Qyf3) that are broken by strands of the Cucamonga Fault, in southern California, at Day Canyon and Etiwanda Canyon. Within this report are detailed the methodology used to collect samples of rock and sediment, determine concentrations of cosmogenic beryllium-10 in purified quartz isolated from the samples, and use those nuclide concentrations to calculate surface exposure ages. This report should be used as the supplementary materials for any publication(s) that uses the nuclide concentrations and/or ages reported herein. This version supersedes all previous age estimates and reports.

These data are an expanded geospatial representation of liquefaction probability for the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data supplement the liquefaction probability analysis completed by Jones and others (2017) for the earthquake hazards volume of the HayWired earthquake scenario, which was the product of an analysis that created a detailed liquefaction probability map covering the northern Santa Clara County and western Alameda County areas. This expanded liquefaction probability dataset makes use of FEMA's Hazus-MH 2.1 loss-estimation software and liquefaction susceptibility data by Knudsen...

These data are a compilation of potential collocations between various lifeline infrastructure systems (transportation, water supply and wastewater, oil and gas, electric power, and telecommunications) components and their potential multi-hazard exposure resulting from the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. Existing hazard data (surface offset, ground shaking, landslide, liquefaction, and fire following earthquake) were combined into a single multi-hazard intensity surface developed for this purpose. Several combinations of potential collocations between various lifeline infrastructure systems components--all...
