Hey HN,
This started as a personal curiosity and Claude helped me build it out.
The Quiet Map reads 98 broadband seismometers from around the world every hour. Ground vibration in the 4–14 Hz band is usually done by human activity - traffic, trains, footsteps etc. Each station is compared against its own history at the same hour of day, and the map names the place currently furthest below its own normal: the quietest place on Earth right now.
Hope you enjoy it and would love your feedback!
