Deposit simulation output Larry Mastin, Hans Schwaiger, Mike Randall USGS

In the video on how to set up model simulations, we started two simulations for Glacier Peak. In this video we’re going to look at the output for the deposit.

• At the end of the simulations, the Ash 3 d job page looks like this • We see results available for both the airborne and deposit runs. • For the deposit run, we click on the “Results” link and it will take us to. . .

. . . A page showing • Summary information and source parameters, and • An image of deposit thickness in inches and millimeters, • With source parameters and the wind file used, • And rankings of “Trace”, “Minor”, “Substantial”, etc. • Scroll down, and we see. .

. . . A list of airports impacted, with • The date and time of arrival of the deposit • The arrival time in hours after the eruption start • The duration, i. e. how many hours the deposit will be falling • The final thickness in mm, • And the thickness ranking, “Trace”, “Minor”, “Substantial”, etc. • Scroll back up. .

Click on this link And you will download a zip file with additional output It includes

Isopach map in millimeters

Isopach map in inches & NWS rankings

A text file of deposit arrival times at airports

The input file used by Ash 3 d

isopachs A shapefile with isopachs that can be opened by Arc. Map

And kmz files that can be opened in Google Earth, with. . . Deposit thickness in mm

Deposit thickness in inches and NWS rank

Deposit arrival times

. . . And deposit arrival times at airports

. . . And a readme document that explains how to use these files.

Some of the kmz files need more explanation, Which is provided in a separate video
