our neighborhood and park have been littered with hundreds of small, rugged orange boxes that say DO NOT TOUCH on them. It turns out they’re seismic microphones, and they’re going to be artificially inducing small earthquakes in the park to measure the local ground response.

Despite the signs, I do wonder how many of them are expected to go missing during the course of the monitoring.
@Maker_of_Things they’re chained to light poles etc where possible, though many of the ones in the park are “chained” to a tent peg, so I’m sure a nonzero number of them will be lifted…
