The Pedestrian Evacuation Analyst is an ArcGIS Pro toolbox that estimates how long it would take for someone to travel on foot out of a hazardous area that was threatened by a sudden event such as a tsunami, flash flood, or volcanic lahar. It takes into account the elevation changes and the different types of landcover that a person would encounter along the way.

The spheroid90gp software package computes surface displacements and cavity compressibility due to pressure or volume changes in buried vertical spheroidal elastic cavities. The software uses supervised machine learning techniques based on parallel partial Gaussian process emulators. The technique yields the accuracy of a numerical model at a computational cost comparable to that of some analytica

This ShinyApp provides users the ability to subset animal diel activity results by species, country, or project.

This repository contains software files, codes, and data asociated with a publication on caldera collapse earthquake cycles.

This document serves as an open code book detailing application of a multi-scale occupancy model to bat acoustic data collected according to the North American Bat Monitoring Program (NABat) sampling design. In this document, we detail a complete analysis of acoustic data collected on Hoary bats in Montana between 2020 and 2022, including: examples of data cleaning and preparation for analysis, mo

Python library and associate web services implementation that allows users to compute collapse risk-targeted design ground motions in accordance with the minimum design requirements of two commonly-used U.S. seismic provisions: the American Society of Civil Engineers "Minimum Design Loads and Associated Criteria for Buildings and Other Structures" (ASCE7) and American Association of State Highway

The CO2assessment package provides R functions and a Shiny application for CO2 storage resource assessment using 2013 USGS National Assessment of Geologic Carbon Dioxide Storage Resources methodology. Tools to facilitate estimation of CO2 storage resources in geologic formations include volumetric and thermodynamic equations and Monte Carlo simulation. The set of input parameters define probabilit

This pyQGIS script and adjoining QGIS layout templates and style specification generate maps from satellite imagery and any derived geospatial outline data that are inventoried and cross-referenced in a tabular inventory file. The maps are intended for mangers, decision makers, and researchers to support real-time decision making and to provide a graphical record that may be publicly shared.

This repository contains code to fit Multi-scale Occupancy Models to survey data for Temblor legless lizards (Anniella alexanderae) This repository specifically contains code to reproduce analyses in: Rose, J.P., Camp, S.M., Sheikh, Z.N., Johnson, C.B., Lei, S.H., Napolitano, G.R., Schoenig, E.J., Macias, D.A., Jordan, A.C., and Halstead, B.J. 2024. Multi-scale occupancy surveys reveal temperatur

RegionGrow3D (RG3D) is a software for computing slope stability on a regional scale within a three-dimensional (3D), limit-equilibrium framework. RG3D efficiently computes discrete, 3D landslide geometries throughout a digital landscape. Potential landslide source areas are identified and grown downhill until force equilibrium is achieved.

This repository contains study materials for python programming for hydrologic applications and a focus on groundwater modeling with flopy. The materials are used in an in-person curriculum at the USGS and provided here for reference for the larger hydrologic community.
