## Reception

Mackenzie, Muschalik & Broesche (2021) provided comments on the 2018 report in three separately authored sections. Broesche believes that Yellowstone should be ranked higher due to the size of the volcano and the popularity of Yellowstone National Park, and Muschalik considers Mount Rainier to be just as dangerous as Kilauea due to its proximity to large population centers in Washington. Mackenzie considers Yellowstone to be just as hazardous as Kilauea.
