Claim 11: “the volcano’s forecast lahar path traverses Washington’s Pierce County, a hub of 150,000 people that’s located just around 60 miles from Seattle.”

MISLEADING

While the lahar path does traverse Pierce County and the mountain is ~60 miles from Seattle, the claim states Pierce County is a 'hub of 150,000 people'. Wikipedia evidence shows the population of Pierce County is actually over 921,000 (2020 census), making the 150,000 figure significantly inaccurate/understated for the county as a whole.
