Tools and Resources

Tools

Several tools are currently in various stages of development and testing. They will be published here when available.

They include:

• An automated method for identifying the source of tephras from Alaska based on their geochemistry

• A web-app used for training your own classification models

• A tool for estimating volcanic erupted volume from isopach (thickness) data using several methods and including confidence intervals for estimations

Code & Scripts

This is where I'll share stand-alone R scripts, models, and packages I develop.

Classification models (R objects) and used for making predictions based on major oxide glass geochemistry for a suite of volcanic sources in Alaska and a supplementary R script are available at the publication webpage: Machine learning classifiers for attributing tephra to source volcanoes: an evaluation of methods for Alaska tephras (supporting information)

Mount St. Helens' Ash in Canada

Did you experience the fallout from the May 18th 1980 eruption of Mount St. Helens? Our research group is interested in collecting and collating the experiences of Canadians following that event, including observations of ashfall. An article in the Edmonton Journal about a recently conducted survey can be found here. Dr Jensen also wrote an interesting blog article about evidence and impacts of volcanic activity in Alberta.

The survey has now been completed. A presentation at the American Geophysical Union: AGU Fall meeting 2019 and a subsequent peer reviewed paper are in the works. Check back soon for updates on this project.
