Technical documentation for the products that the operational aftershock forecasting (OAF) system transmits to PDL. The "oaf" product contains the aftershock forecast, and the "event-sequence" product contains the earthquake sequence definition.

Desktop GUI software used by analysts for operational aftershock forecasting (OAF). Can load data from Comcat and other sources, fit aftershock model parameters, generate aftershock forecasts, and display plots of the results. An analyst can adjust model parameters, select forecasting options, send commands to the OAF servers, and send forecasts to PDL.

hydroloom is a collection of functions to work with hydrologic geospatial fabrics. hydroloom is designed to provide general hydrologic network functionality for any hydrographic or hydrologic data. The package is intended for developers of workflows and other packages that require low level network and network data manipulation utilities. v1.2 adds downstream accumulation functionality...

The software release combines USGS streamgage data and NOAA precipitaion and storm track data to highlight where floods occurred, how long they lasted, and how storm intensity evolved. This kind of integrated data is critical for emergency response, risk communication, and long term planning.

A Python package to locate emergent seismicity using network of seismic stations. enveloc uses envelope cross correlation of seismic traces on a fixed time window and performs a 3D grid search to maximize signal coherency. The location process can be performed interactively with on single short time window, or more automatically on longer data sets by internally cutting data and...

A New Perspective on Eruption Triggering (ANPOET). Python code in support of publication: Prejean, Gomberg, Bodin, Pesicek, Taveras, A New Perspective on Eruption Triggering, Nature Communications, in revision. This python Notebook runs the same analyses documented in this paper by Prejean et al. (2026), or you may run it with your own earthquake catalog and volcano. The code should to...

Repository to investigate CWD spread using the first time of detection by county and comparing those results to what would be predicted based on deer movement distributions.

This software estimates the current and projected distribution of Arizona Toad (Anaxyrus microscaphus) based on environmental conditions and perceived threats. It fits an integrated species distribution model to quantify relationships between covariates and relative abundance of Arizona Toad using species data from a variety of sources.

ipensive is a tool for processing infrasound array data. It was developed for volcano monitoring for operational use at the Alaska Volcano Observatory and has been slightly generalized for broader use. The code processes infrasound and hydroacoustic array data in 10-minute increments, generating images and a webpage for displaying/navigating those images. Much of the package is a wrapper...

This document describes the peer-review and reconciliation process for version 1.0.0 of the kinematic-wave-model software package. The repository containing the referenced review items is located at: https://code.usgs.gov/ghsc/lhp/reference/kflow

CoastSeg is an interactive browser-based program that aims to broaden the adoption of satellite-derived shoreline (SDS) detection and coastal landcover mapping workflows among coastal scientists and coastal resource management practitioners. SDS is a sub-field of coastal sciences that aims to detect and post-process a time-series of shoreline locations from publicly available satellite...

This doi is for the supporting code for the following manuscript "Constraining sources of mid-Pleistocene to present explosive volcanism in the Gulf of Alaska using machine learning and compositional data analysis" by Jordan Lubbers, Matthew Loewen, and Kristi Wallace — in review G cubed
