Well, Congress passed a law about it after the last marathon shutdown, but laws seem to be pretty optional these days so 🤷♀️

There's a great paper by Dave Hill (former USGS seismologist) about the Mammoth crisis at link.springer.com/chapter/10.1...) He spent much of his career running the Long Valley Observatory (now CalVO) and working to repair trust in the USGS in Mammoth.
Volcanic Unrest and Hazard Communication in Long Valley Volcanic Region, California
The onset of volcanic unrest in Long Valley Caldera, California, in 1980 and the subsequent fluctuations in unrest levels through May 2016 illustrate: (1) the evolving relations between scientists mon...

Making hazard maps is HARD, too. So many questions to answer before drawing lines! Do you show where hazards have been or where they might go in the future? Will the volcano behave the same way it did in the past or throw you a curveball? Do you show the worst case or the most likely scenario?

I should point out that the USGS is not the agency that makes decisions about exclusion zones. Recommendations, yes, which do err on the conservative side, but it is the emergency managers' call where to draw the lines.

You can also get different plume colors depending on how the light is scattered by sulfate aerosols! www.usgs.gov/observatorie...
Volcano Watch — Colorful plumes – can we see volcanic gases?
When volcanic gases are released into the atmosphere, resulting plumes sometimes appear to have a faint color. Is this color indicative of a certain gas present? Answering this question requires descr...
