Estimated origin - interesting, not definitive
The red marker is our best guess at the source; the blue dots are where people were. Estimated from how strong it felt across the area - loudest closest to the source. There aren't enough direction arrows yet, so this leans on the loudness pattern alone. A few people reporting which way it came from would sharpen it a lot.
