An updated geospatial liquefaction model for global application
Jing Zhu, Laurie G. Baise, Eric M. Thompson
2017, Bulletin of the Seismological Society of America (107) 1365-1385
We present an updated geospatial approach to estimation of earthquake-induced liquefaction from globally available geospatial proxies. Our previous iteration of the geospatial liquefaction model was based on mapped liquefaction surface effects from four earthquakes in Christchurch, New Zealand, and Kobe, Japan, paired with geospatial explanatory variables including slope-derived VS30, compound...

Spatio-temporal mapping of plate boundary faults in California using geodetic imaging
Andrea Donnellan, Ramon Arrowsmith, Stephen B. DeLong
2017, Geosciences (7) 1-26
The Pacific–North American plate boundary in California is composed of a 400-km-wide network of faults and zones of distributed deformation. Earthquakes, even large ones, can occur along individual or combinations of faults within the larger plate boundary system. While research often focuses on the primary and secondary faults, holistic study...

Michael P. Finn, E. Lynn Usery, Laura N. Woodard, Kristina H. Yamamoto
2017, Book chapter, Choosing a Map Projection
There are undeniable practical consequences to consider when choosing an appropriate map projection for a specific region. The surface of a globe covered by global, continental, and regional maps are so singular that each type distinctively affects the amount of distortion incurred during a projection transformation because of the an...

Prediction and visualization of redox conditions in the groundwater of Central Valley, California
Celia Z. Rosecrans, Bernard T. Nolan, JoAnn M. Gronberg
2017, Journal of Hydrology (546) 341-356
Regional-scale, three-dimensional continuous probability models, were constructed for aspects of redox conditions in the groundwater system of the Central Valley, California. These models yield grids depicting the probability that groundwater in a particular location will have dissolved oxygen (DO) concentrations less than selected threshold values representing anoxic groundwater conditions,...
Computer modelling for ecosystem service assessment
Robert Dunford, Paula Harrison, Kenneth J. Bagstad
2017, Book chapter, Mapping ecosystem services
Computer models are simplified representations of the environment that allow biophysical, ecological, and/or socio-economic characteristics to be quantified and explored. Modelling approaches differ from mapping approaches (Chapter 5) as (i) they are not forcibly spatial (although many models do produce spatial outputs); (ii) they focus on understanding and quantifying the...

2017, Report, A sourcebook of methods and procedures for monitoring essential biodiversity variables in tropical forests with remote sensing
One of the candidate essential biodiversity variable (EBV) groups described in the seminal paper by Pereira et al. (2014) concerns Ecosystem Structure. This EBV group is distinguished from another EBV group which encompasses aspects of Ecosystem Function. While the Ecosystem Function EBV treats ecosystem processes like nutrient cycling, primary production,...

2016, Special Paper of the Geological Society of America (520) 159-170
Groundwater is the source of drinking water for ∼1.4 million people in the Coastal Plain Province of Maryland (USA). In addition, groundwater is essential for commercial, industrial, and agricultural uses. Approximately 0.757 × 109 L d–1 (200 million gallons/d) were withdrawn in 2010. As a result of decades of withdrawals...
