These quakes happen all the time in Mammoth.
It’s on a volcano. It’s on the caldera.
Sometimes there can be tragic consequences. Maybe ten years ago one of the daily quakes shook loose a chunk of ice from the roof of a school and fell on a little girl.
That is very true. Mammoth Lakes is an active yet dormant super volcano like Yellowstone. These earthquakes are perfectly normal and means that an eruption could occur sometime within the next year or 10,000 years from now. The same could be said for Yellowstone.
