Last year, scientists discovered tens of thousands of previously unrecorded earthquakes which could be hinting that Yellowstone's supervolcano is building up to an eruption.

That’s a head-scratcher for me. How do you discover something that wasn’t recorded. Were their reams of seismographic printouts or such collecting in a basement that were left uncatalogued or whatever?

…Sounds convenient for ginning up a skeer.

The really big one in Missouri was felt in Boston-1805.
